[Q] galaxy tab 10.1 not booting up - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

Today, when I turned my tablet on, I immediately noticed two things. One, the battery was critically low. Two, my homepage looked strange. Everything was not only fuzzy, but it also had a "thermal camera" effect, where everything was either bright yellow, red, green, or blue.
I had to board a plane at the time so I was like, "Fudge. I'll deal with this later" and shoved it back in my purse.
When I got to my hotel, after having charged the tablet for several hours, I tried to boot it up but it wouldn't work.
I restarted the device but that didn't fix the problem either. Now it just stays on a lit up blank black screen. Occasionally static horizontal lines will flicker across the screen but mainly it remains as the lit up blank black screen of death.
Please help! I am not computer or tech savvy. I also did try holding down the power and volume keys simultaneously as others suggested but that didn't work either. Please help. Thanks guys.
This may be important info: I felt my tablet get really hot two days ago.

I'm not really sure but this sounds like a busted digitizer. And that's hardware. If your computer can still read from your tab while it's booted up and connected now would be a really good time to save all your data. You could take it to a repair shop. If it's not too expensive to fix do it otherwise I would be looking at a new tab.

Press briefly on Power button while it's charging. If you don't see the battery charging icon I'm afraid it's a hardware issue.

[Q] Please help blank white screen huawei U8120

While I was opening the camera app yesterday the screen just turned white, tried using the power button to switch it off and it didn't respond so I had to pull the battery out, when it booted it just stayed white.
Tried recovery mode same result the screen stayed white.
I connected it to the pc using MyPhonExplorer and took a screen shot it showed the normal home screen, so used I it to navigate through the phone by refreshing the screen shots and did a hard rerest that didn't help it stayed white.
The same white screen thing happen 3 weeks ago while I was playing music, that time I just pull the battery out and everything worked again. I'm not sure if its a software or hardware problem and how to fix it.
The phone has a custom rom and I have been using it for the last 4 months with no problems.
sorry to hear. not sure what the problem is but seems to be a problem with the display itself or its connectors. only other way to make sure its not software would be to flash a new rom i suppose

[Q] Dead Razr - Weird Overheat Death! Anyone?

Hello,
I was at a concert last night, and took a few pics and videos on my phone..when I put it back in my pocket it became overheated - then the screen went blank. I could feel the heat almost burn my leg. From this the LED flashed a full variety of colours (greens,purple & white) and when pressing the power button nothing happened. It eventually started flashing red as I drove home but refused to come back on. I put it on charge when I got home where it was a very faint white colour LED. I did the manual reset (power&volume down)..nothing.
It's been on charge all night and it was just dead - no light - nothing this morning. I've charged it this morning at work, and there's a white light, sometimes faint, but trying to start it is impossible.
I'm now left phoneless as my spare phone doesn't take the Micro Sim card. I have insurance, but they want a £50 excess - I've contacted Motorola as this seems to be an internal electrical fault, but I was wondering if anyone has any hints or tips as it could be weeks before I have a phone again.
Anyone experienced / managed to sort this themselves?
Laura
Hi Laura, welcome! (I hope BRFC doesn't stand for Bristol Rovers!?)
Are you able to actually turn the phone on at all, ie get any screen to show?
I would imagine that the phone is newish, it's still covered under warranty so it may be worth contacting motorola directly to see if they are able to do anything.
When you plug it into your pc/mac and try and turn it on, does the pc pick up the phone at all?

[Q] Help with strange Note problem

Hi, my Note has been running happily for months now, I was running the latest version of Super Nexus before the thread closed, and I was using a custom kernel, UBER I believe, its been so long since I've had to mess with it. For the record I have never overclocked, I refuse to.
Anyway, every two or three months my phone would start to get unstable, lots of apps installed etc etc, and my screen would start to flicker when I was on the home screen, sometimes the screen wouldn't wake up from the lock screen so I'd have to hit the button a few times, random reboots every couple of days, things like that.
My phone is so stable for the first couple months though, that I never bothered to change anything, I just wiped the phone clean, wipe all the cache etc etc, then I'd reinstall the ROM, and then reinstall the kernel, and bam, it was good as new again, fast and fresh.
I've done this a few times now since May 2013 when I first got it stable.
But now it has done something weird, scary even.
Its been getting buggy lately as usual, but I've been to busy to reinstall everything, so I just kept dealing with it, its been buggy for over a month now, and tonight it randomly rebooted, but didn't boot fully.
If I take the battery out and leave it out, then put it in, it automatically buzzes once, then the Samsung logo shows up, disappears, and if the room is dark you can see the screen light up black, flicker slightly, then turn off. Pushing the power button again does nothing, it stays off.
If I plug the charger in, the battery icon shows up with a spinning circle in the center, then the screen goes dark and the phone buzzes repeatedly every 3/4 of a second, buzz buzz buzz buzz etc, seemingly endlessly.
If I hold the two volume buttons and power button down, and release when the samsung logo shows up, so I can enter into TWRP, nothing special happens, the logo shows up, disappears, screen goes dark.
BUT, I did some searching and decided to try using ODIN to go back to full stock att. So I took the battery out, hold down the volume- button, put the battery in and voila! I get into download mode! I push the volume+ button and its starts waiting for the target (or whatever its called).
BUT, then the screen goes black and its dead. So I thought maybe just the screen is turning off, so I set up ODIN, started download mode, plugged in the USB, and the computer recognized it and made the appropriate sound, but as soon as the screen went dark the computer made the 'USB disconnected' sound and said device installation failed. So I am assuming its a bigger problem than just the screen, the entire thing turns off.
Its late now and I'm frustrated and don't know what to do, any help would be gladly appreciated. Hopefully there are still people using this phone.
Thanks again,
-Tom
Stuck power button.....flick the back of your phone a few times to jar it loose. It may sound and feel normal but try anyway
Or
Check for bad battery....... Does it appear or feel swollen? Very Commons need to replace after about a year. $8 on Amazon.

Thank you for your response, this makes sense. I have flicked and played with the button, it appears and sounds to be working properly, but I am going to take it apart tonight to be sure. I've had it apart before, I had to do the GPS fix, so I won'tbreak it, but thanks for the new direction to go in!
I will report back.
Also, I have 4 batteries I alternate with and they all have the same effect :/
Thanks again!

After some research on faulty power buttons specifically, I realize this this a fairly common problem, and as such I apologize for my not realizing this sooner.
But its fixed! I took it apart and got it to work by lightly tapping the button with a small screwdriver, I then did some research and learned you can sometimes clean it with rubbing alcohol. I didn't have any rubbing alcohol, but another quick search determined that vodka can be an acceptable substitute. So I poured a shot of grey goose and went to work lol. I put a small drop right on the button and clicked it lightly but repeatedly for a minute or so, then I blew it out, then dried it with 30sec or so in front of a space heater (its winter here, -19f, brr), put the battery in and voila!
Very happy now, if it acts up again I will try actual rubbing alcohol, but if that doesn't do it then their are guys on ebay who will replace the button for $15-40, so I guess thats better than nothing.
Thanks again!

[Q] galaxy S3 dark scrren

My galaxy S3 is showing a very weird problem. I was using the phone and before reaching home the battery when completely flat. When I arrived home and plugged the phone to the wall charger the screen remains dark, black. Now the battery is full charged (green light) but the screen remains to the same estate. When someone calls me the phone rings. When I plug it to the computer I can see the files inside the different drives. I reinstalled the OS that is 4.3 but still same problem. I didn't drop the phone and It didn't have any shock.
That is weird. I am thinking of a dead screen but before going for a chirgucal operation on my beloved phone I wanted to ask if that couldn't be a software problem.
Happy to hear from your experiences.
Boot into download mode, volume down + home then power button. If the screen is dead in download then it is hardware.

never heard this type of problem
try to go into recovery and check if it displays anything
If successful do factory reset
In download mode i can see nothing. That is really weird. I am letting the battery drain completely and i will check. Thank you for your replies
I wanted to upgrade so far what i am getting. The screen while dark, black is reacting to touch actions: for exemple when i lock the phone with the power button i can hear the lock sound;when i unlock with the lide action on the screen, I can hear the unlocking sound. I think that must be a weird system problem. If the screen was broken will it react to such touch actions?
Lide=slide. I can actually take a call with the slide action on the screen. When someone calls me i just have to slide my finder at the proper place on the screen to take the call. I need help please.
Most probably its the hardware. Your LED seems to be ditching you. And yes a bad led can still response to touch despite of being black all the way. Actually it's the digitizer that responds to the touch NOT the LED itself.
In your cas3 so far from your feedback I can say that you are having a bad LED everything else including the digitizer is working well.

Samsung Galaxy S2 i9100 Won't do absolutely nothing.

I have a certain problem with my Samsung Galaxy S2. It's a bit old now, It has about 4 years with me. A couple of days ago, I was charging my phone and it was a bit hot. And I recieved a call. I answered it, and the phone went black. I tried turning it on and, nothing. All it showed was a blue screen with a black circle on the top left corner. The phone hasn't gotten any bumps or has fallen out of my hands or anything of that nature. I decided to turn it off, take out the battery and not touch it for a day. I placed back the battery the next day and, this time, nothing shows up. Today, I decided to use it again, and connect it to my laptop, and the laptop detected it. I really don't know what to do. Is there a fix for this problem? I'd appreciate your help. Thanks.
is downloadmode working (when phone is off, do voldown+home button + power button)
