usb>mhl>hdmi>hd tv issues. - HTC Amaze 4G

Picked up the mhl converter at a T-Mobile shop, grabbed 6' of hdmi cable, hooked up the phone to my newest tv, and "no signal" bounced all over the screen.
Mocking me.
Hdmi 1
Hdmi 2
Hdmi 3
Nope, zippo.
Dead USB? No, the USB>TV worked for pictures and file browsing.
Faulty MHL adapter? No way of knowing.
Dead HDMI TV inputs? All 3 on a 2 week old tv? Possible.
I called technical, and they were stumped as well.
I have 2 units, and neither worked.
Am I missing something?
Operator error is not unfamiliar to me.
Thank you.

Plug the mhl to power and tv first. Plug the phone last

Tried it, no luck.

I tested mine out to see if I could re-create a no signal and the olny way I did was when I set the signal to HDMI on the tv first, then plugged in the mhl. I guess it needs to have that signal there first to pick it up. Anything else I tried, different configurations of plugging in worked.
Does your mhl have a micro usb plug to charge as well as the hdmi plug? I have a generic one off ebay that has the short micro usb pigtail for plugging in your wall charger into the mhl and also a short pigtail for the hdmi plug. I have read a couple people were having problems with the one that's hdmi out only

Well, I solved the first problem.
Thank you everyone that assisted.
Now my only problem is that I paid real money for the kit.
I do not advise purchasing.
The output is horrendous.
I tried my vids/pics, youtube...no netflix yet...everything was pixelrama.
It should have raised flags that not only tmo tech, but 3 stores in the area are completely unfamiliar due to nobody buying them or trying them personally.

[Q] HDMI Adapter in Box?

Did anyone receive the HDMI adapter in the box for the AT&T Galaxy S II ? I read that it should be included but did not receive it.
Nope. Not in the AT&T box
10 char xxxx
Nope. It doesn't come with AT&T version. AT&T version, all you get is the phone, battery, ac charger, usb cable, $25 media hub (tv shows only), manuals.
The infuse comes with one. The galaxy doesn't included one.

curoius, do most newer tv's have MHL built in? or probably not?
all i can find when i type my tv's model number and MHL into google is.. my tv with some hockey info (NHL) hehe..
google is too smart for its own good sometimes.
Based upon what I've seen, you need a MHL adapter for the phone. Its just a little box that plugs into USB, and had a USB port on it for power input and an HDMI port. There's cheap out there, like this one.
I have an MHL adapter and it does work but you need to plug the power into the thing in order for it to do anything. My receiver has usb and hdmi on the front so that works for me. It would be nice to have 1 cable, but this works.
Unfortunately I believe that's the case with any MHL device. There's a chip inside that box that transcribes the MHL signal (coming over the 5 pin USB connector) to a full HDMI signal, and it requires power. It's not all that bad though, as you would probably want to be charging your phone while playing a video anyways.
Exactly it is nice it does have power. Unlike the ipad to vga dongle lol.
Eventually most of the high end TVs will have the MHL. You will still need the adapter but you will not need to power it. The TV will not only power your phone but charge it.
I pocketed the HDMI MHL adapter from my infuse when I returned it under the 30 day ATT trial... The screen was pixelated in my infuse in the top left hand corner so they were more concerned with my device being defective than me just not liking it and only asked me if the charger was in the box.

[Q] 11 Pin MHL + USB OTG

Hey there, i have tried gathering information about this subject and it seems all threads always lead to this announcement:
http://www.gottabemobile.com/2012/06/29/galaxy-s-iii-new-mhl-connector-also-enables-usb-on-go/
Short: Samsung have changed to an 11 Pin-out to enable USB OTG and MHL Hdmi out at the same time. I purchased an original HDTV Adapter (EPL-3FHUBEGSTD) which as far as i can reliably count indeed has about 11 connectors inside the USB connector that goes into the phone.
Now, i can get HDMI out just fine, but ONLY when i also connect the MHL adapter to a power source (a PC USB Port will do fine), however i have also read, that the phone is able to power the MHL adapter itself but obviously would not be charged then (no surprises there). This does not work however.
Further, connecting a USB OTG cable to the micro usb port on the MHL adapter does nothing. No notification and no devices connecting. No power either, since the LED on my USB Hub does not light up as it should. Connecting any devices to the hub does nothing to change that situation. If i leave out the MHL adapter and connect the USB OTG cable directly to the phone, everything works perfectly. I have tried this with 2 different OTG cables so they are not the problem.
This is an original genuine HDTV Adapter for our phones, which according to that post should be working fine with USB OTG.
AFAIK, this topic --does-- come up more frequently now as i can find a few more discussions about it, albeit none really helpful:
http://android.stackexchange.com/qu...-of-11-pin-mhl-connector-in-samsung-galaxy-s3
http://forum.xda-developers.com/showthread.php?t=1743128

http://en.wikipedia.org/wiki/Mobile_High-Definition_Link#11-pin_MHL-USB_Connector
http://forum.xda-developers.com/showthread.php?t=1811435
That wiki entry is the most interesting link as it definitely states that using MHL and USB OTG simultaneously is possible and is also the reason why the 5 pin layout was changed to an 11 Pin layout.
Looking forward to reading your replies!
the ability to use MHL and OTG simultaneously would give the S3 so much more purpose. It is powerful enough to replace a desktop computer used only for light stuff like browsing and watching videos, and even simple gaming. If samsung made a dock like the one for the motorola atrix I'm convinced they will broaden their target group. The atrix got everything right with this but is inferior hardware wise. I love the idea of a one device for everything concept. Unfortunately it doesn't rhyme very well with the growth society.
Love the MHL and the OTG is even better only after I got the correct cables as the cables changed on S3 to the S2 version, unlimited space for watching films on my phone is now awesome and even better connecting it to to the TV just need a good dock,
is there perhaps any expert advise on this? According to multiple sources it should work but really doesnt. Did i buy the wrong mhl adapter?
I think they will only both work together when being used with an MHL enabled tv. That way the power comes from the tv and the usb on the adapter can be used for the usb-otg cable.

But if i connected the MHL with the s3. Would sound come out of my phone AND my TV or just my TV. If it justs comes out of my TV, then can i hook up my bluetooth headphones and listen to my video or it would not allow me?
Thanks

Ah ok sorry! Afaik you should be able to choose your headphones as primary audio source in the bluetooth settings. I know I can choose what I want to be output to my bluetooth headset, but I don't own an MHL adapter so I don't know about that. Someone with one should be able to try it, and if they don't own a bluetooth headset/pair of headphones they could try with wired ones and see what happens.

I have recently received an MHL connector (5 pin type) and the samsung 11 to 5 pin adapter for it. I can confirm that if I plug my OTG cable into it, and then into my powered USB hub, I can get the MHL to work just fine, both video and audio. The OTG cable powers it just fine, but does NOT allow me to use other devices attached to the USB hub.
I am still researching. I suspect you need to bring all 11 pins off the phone with a splitter of some sort, or possibly wire data lines through the MHL. Probably not with the 5 pin MHL connector and 11 to 5 pin adapter, but with the full 11 pin MHL adapter. I am not up to that level of hardware hacking. I suspect whoever does it first can sell a BUNCH of them!
Oh, and I have a Moto Lapdock for my Raspberry Pi, and would love to hook my S3 to it too!

Why do I need charger power for Samsung MHL Adaptor?

I was under the impression that Note 3 supported MHL 2.0 but when I plug in the official HDTV adapter from Samsung (model number ET-H10FAUWEGWW) I still need to also use a USB charger to get it to show through the HDMI input on my TV?
If I don't I get a continual on-screen message on the phone "HDMI cable connected/disconnected" flashing/cycling until I plug-in the Micro USB charger cable on the side of the HDTV adapter.
Any thoughts appreciated
Your TV would have to have the MHL adapter which would mean you would have had to buy it most likely this year. If you are just plugging it into a regular HDMI slot there is not power available this is why you need to hook up the adapter.

I believe you may have ended up getting a copycat adapter (A 1.0 instead of a 2.0), not official. I recently purchased a MHL 2.0 off amazon for $10 and it works just plugging in the tv hdmi without power. The one I got isn't a samsung one, but it is compatible with samsungs (11-pin I believe). The tv I'm plugging into is an OLD tv (got it when hdmi was just coming out) and it works without using an external source- also working fine on my newer tvs. I believe the power for MHL 2.0 is suppose to come from your phone so the tv shouldn't be the problem.

You definitely do not need an MHL input when using this adapter. The whole point of the adapter is to go from MHL (the Note 3 output) to HDMI (the TV input). If you have an MHL input on your TV or receiver all you need is a cable (basically what's in the white box is built into your TV already).
I second the opinion that you got a knock-off. I have both adapters from Samsung and neither of them need external power to operate with a Note 3.
The only restriction with the MHL 2.0 adapter is that it requires that you plug it into a TV and not a receiver, and it will tell you in no uncertain terms if you don't plug it in correctly.
The only reason to plug in power is that it stops your battery draining so fast, the charger provides about 700mA charging current to the N3.

Here's the link: http://www.amazon.com/VicTsing-Micr...e=UTF8&qid=1384305065&sr=8-4&keywords=mhl+2.0
Fair warning though; this adapter is not perfect by any means, you can read my review on amazon (the one that tested it out on the note 3). As noted in my review, I am still waiting on a replacement one (since the original one I got functioned but didn't charge when I hooked up my power adapter), and I'll let you guys know if it's better once I receive it. Even though it doesn't function perfectly, for $10 dollars it does the trick.
Edit: They are sending me an extra without having to return the original, so even if the second one doesn't charge, at $5 a pop I'm happy.

Thanks for alerting me to the counterfeit reasoning that shows this part must be a copycat, I contacted the supplier of this part to us for a partial refund as I will use this as a backup and try and buy an original and prices drop from the £39 or take advice of the other replies in this thread and find a genuine 2.0 MHL non-Samsung version. I'll report back if I have any trouble with the supplier claiming that it is a genuine part and see how far eBay support me.

I've read that you need to plug into a TV but haven't had problems. But I am using a samsung mhl 1.0 with 11pin adapter. Didn't need power also. Waiting for Samsung to get on the ball so I can buy a genuine mhl 2 from them.

I bought the Samsung one before it went out of stock and it works in any HDMI input also without the need to plug it to the power outlet, but I'm sure a full HD movie will drain the battery fast..

I think for the price of the official one your better off just getting a wireless dongle, unless you plan to game with it.
Hi guys, here's the response from the eBay seller, "These items were purchased From Kondor Ltd who are one of the major UK Distributors of Samsung Accessories. I would be extremely surprised if they sold fake stock and risked losing there multi-million contract with Samsung over some cheap fake stock. I can only assume the item received has a manufacturing fault of some sort as this is the first problem we have encountered for this product sorry.", so as you can imagine I'm beginning to think there my be a fault with my phone if this message is to be believed, what do you guys think?

The MHL 1.0 adapter doesn't care what it's plugged into, only the MHL 2.0 adapter has that issue.
I just bought a mhl cable through amazon. It has the USB connector for the phone on one side, and a HDMI connector on the other. Directly attached to the HDMI connector is a regular USB plug which I plugged into my power source for my phone (as this is how I understood it should work).
I don't get any messages on my phone that indicate that it is connected to my TV/Monitor and my phone also doesn't indicate that it's charging.
What I read from the product description was, that connecting this cable to my power source would also charge the phone. So could it be my phone is charging, even if the battery indicator doesn't say so? Like it would be charging just so much as that my phone doesn't drain? Or should it clearly indicate that the battery gets charged. Befor knowing this, I'm hestitant to send the cable back as defective.
Can any one advise?
Thanks

You're welcome.
I love using MHL, but I really wish there weren't several varieties of MHL cables (5-pin, 11-pin, 1.0 and 2.0) and also such a large number of fakes and very low quality ones out there. Makes buying difficult, as all these threads about MHL demonstrate.
Does anyone know if you can physical see whether you have a 5 pin or 11 pin MHL 2.0?

HDMI Cable

I purchased the Amazon Basics micro HDMI cable (http://www.amazon.com/AmazonBasics-High-Speed-Mini-HDMI-Cable-Ethernet/dp/B003ES5ZR8/ref=sr_1_1?ie=UTF8&qid=1419968500&sr=8-1&keywords=mini+hdmi) and I've been having issues with poor or no connection. The first time I connected the tablet everything was great. I played about an hour of Portal with no issue. I had to reboot the tablet, and after that I couldn't get a signal. I tried the HDMI cable in my Canon 70d and had no signal. I assumed that the cord was bad, but last night I tried again and got a good signal for about ten minutes. I had to change the source on the TV and when I went back to the original input, my signal was gone. Has anyone else experienced this with the Amazon HDMI cable or any other HDMI cable? What are some good low-cost HDMI cables that others have had success with?
Ive used this adapter a few times without issue. http://www.amazon.com/gp/product/B00IZYIYX8/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 .. If the cable is giving you an issue with multiple devices can it be the TV?

I plugged the cable into all of the HDMI ports on the TV and one on my Sony receiver. It seems to react the same way with both devices. But that adapted you linked looks pretty slick.
Sounds more like a bad cable than anything else. If you replace the cable and it continues then the shield would be the next more likely culprit. I haven't heard of this happening to anyone else, though.

Galaxy S8 HDMI not working

I bought the ADAM elements CASA H01 USB Type-C to HDMI Adapter Gold, I tried connecting HDMI to my S8, S8 says HDMI connected but the TV has no response. I am sure the TV works with HDMI as I tested my XBOX on it. Is there anyway to make it work? Or is my adapter broken?
you can try things like switching the tv off/on and the phone off/on whilst its connected. sometimes, not often, that will help
it sounds like hdmi handshake issues. basically a compatibility problem between the phone and the tv.
Thank you for the suggestion, I tried but still doesn't work. If it's a problem between the phone and tv, should I try the adapter on other tv?
I used Choetech USB C to HDMI 60HZ cable to my S8. Everything worked well. https://www.amazon.com/CHOETECH-Thunderbolt-Compatible-MacBook-ChromeBook/dp/B06XP9NV4G/ref=sr_1_5?ie=UTF8&qid=1495422430&sr=8-5&keywords=choetech+HDMI
I had some HDCP issues when I tried connecting my S8 to a capture device, but that was due to a poor quality cable.
Make sure your device can read the HDMI signal coming from the phone too. It appears to send 1080p or higher, so if your device only understands 720p (some smaller TVs are like this) it might not be able to see the signal from your phone.
I'm having same issue hubbies works mine won't same cord and tv???
Any idea what's going on I just factory reset my phone and still doesn't work
I just got an hdmi to USB c adapter today as well and I first connected it it did not recognize my phone either. The thing that seamed to do the trick was attaching the adapter to my phone first without the hdmi or power cord, then powercord then connecting the hdmi cord and all works well
still not repaired
4 repair invoices 3 months and still not repaired currently on hold with Samsung .... i'm not impressed as this feature was a huge decision for buying the S8+
i use baseus usb-c to hdmi cable - all work good (but no dex)
I have tried two different usb-c to HDMI cable adapters and can't get neither of them to work. Any ideas thanks
Broken and need help
I have a Ugreen Adapter for usb-c to HDMI cable, it worked very well
On several tvs, it WAS working here in Mexico on my ATVIO tv, then I did some phone cleanup and it STOPPED, is there a special application or setting that I've uninstalled????, I'm lost without YouTube on my tv LOL , cant find info anywhere and I swear I installed something on my phone to get it working like 7 months ago in Dallas LOL
biggest thing iv found with EVERY usb type C connectivity issue, POCKET LINT. its as simple as using a sewing needle or safety pin to CAREFULLY take the pocket lint out of the type C port on your device, there are 30 individual pins in there, and they ALL need to make a good connection to your adapter. brand does not matter, if it works with phone A phone B will figure it out (unless your phone simply doesnt support mhl adapters)
Same problem - Galaxy S8+ with Choetech USB-C to HDMI adapter. Worked a couple of months ago not working now. Wife's phone (exactly the same) work a with adapter and HDMI cable. Cleaned, powered on/off, reset phone, nothing works. So frustrating. Any ideas?
I was using my S8+ with my TV. After a couple updates ( prior to Pie) no longer worked. Please don't suggest turning things on / off or factory reset.... The cord is fine. My phone just now updated to Pie, I thought great, maybe it will work again..... nope... I've contacted Samsung, same BS runaround. Samsung - must be a compatibility issue, Me - it was working, Samsung - must be the cord, buy a new one, Me - already did, tried two different brands, Samsung - was one of them Samsung, Me - ......., Samsung - try factory reset, Me -....... by this time I know I'm screwed. There WAS something to do with an update. (And yes prior to the Pie update I did a factory re-set with no results). From the comments on this post appears no one has a solution....
