I have replaced a lcd display a some time ago. The replacement LCD was working fine, but after a few months the replacement lcd display is showing a strange and wrong color gradient. It looks like old 16bit colors...
My hardware related question, could this problem be cable or lcd or mainboard related?
Yikes. I'd suspect a physical issue with the display. What do you see when you connect to an external HDMI screen?

When the hdmi cable is plugged between tablet and my tv, there is nothing wrong with output.
Today i have replaced also the flex cable, that did not help either.
Could the problem on lcd dispay be fixed? :'(

I'm speculating on the damage being with the LCD. I'm an IT professional (20+ years), so I do have a bit of experience here. One thing that's concerning is how the screen is separated, vertically, into the four bands. LCD screens are ridiculously delicate. I know from experience, having broken mine when replacing the digitizer glass.
LCD screens are typically very difficult/impossible to repair. It's cheaper/easier to just replace. I know this sort of sucks. Perhaps you can buy a replacement from a vendor that has a decent return policy. I'd use rubber gloves to handle the replacment (no fingerprints). Temporarily connect it. Problem gone? Then it was your LCD. Problem persist? (unlikely). Repack and return the replacement screen.
Good luck.

OK I have ordered a new lcd display, lets hope this will solve my problem.
Thanks everyone for your reactions.

So, about 2 weeks ago, I got my HD2 off of Craigslist with a cracked screen. It worked perfectly fine with the exception of the hardly noticeable cracks. I knew I could get the replacement digitizer/screen for $40-80. I got my screen in the mail yesterday and, following the "YouTube" video tutorial found on this site, I......ugh.... replaced the screen....................I SCREWED UP BIG TIME!
First, I broke the ribbon cable for the Side "Volume Up/Down" buttons. Then, I broke the ribbon cable for the "soft keys." Ah, crap, but oh well. I figured I could use the touch screen for pretty much everything i needed to do. Well, while prying the cracked digitizer screen from the LCD, I went a bit too deep & peeled the tinted film off of the LCD. I thought nothing of it at the time. I'd already done enough damage. So the display would be a bit brighter than normal oh well.......WRONG! I put the phone back together and once I get it to power up, all I get is a white screen. I thought I missed something. So I disassemble & check 3 more times. Still a white screen.
Well, after all of this, the new digitizer/screen doesn't want to stay in place very well. So, being pissed off and curious, I pull it out and away and notice in the backside reflection of the digitizer that I can slightly make out the phone display. So, apparently the "Tinted Film" that I accidentally peeled off of the LCD makes images visible on the phone screen. I kind of damaged this film when peeling it off. Therefore, I am unable to put it back on. Does anyone know of a simple fix without replacing the LCD?
SORRY FOR THE "SHORT STORY LONG."
I was brainstorming and thought that maybe the film was polarized. So, I grabbed my sunglasses, which are polarized, and wearing them, I can faintly see the display. Anyone think maybe polarized window tint might fix my problem?
Hey man I have some electronic devices that need repair, can I send them to you to fix them?
SURE!
You can pay me in HD2 parts.
Sir i can only say 1 thing. search ebay and replace everything you damaged. only that way you will get your hd2 in perfect state.

I'd go one step further and say bin it and get a new one!
You sound just like me. That is why I never try things like that anymore. Hope it gets sorted but might be better looking for a used one.
I've got it functioning...
I found the film that I ripped off, put it over the screen and........I CAN SEE! However, the top half has lines through it. So, I must've damaged the LCD. The good news is that my phone is useable again. I just have to do everything via the touch screen and can't let the screen hibernate unless I have my charger close by. I'm just gonna keep my eye out for a cheap busted phone and eventually have a 100% phone again...
I sympathize with you. I broke HD2 while I was trying to check for loose WiFi card cable(cuz i was getting weak WiFi signals). The cable turned out to be fine but the external speaker stopped working. I opened it up again and adjusted some parts and it just got worse. the HD2 didn't power on at all. I tried fixing it but to no avail. I ended up sending the HD2 to a repair shop and was charged $170 for the repair. the repair guy said i messed up the power IC and the connector for the external speaker and he had to replace the power IC and resolder the connector.
I think I'm gonna stop trying to open up expensive phones. i was stupid thinking that since I have successfully replaced digitizer for my previous Palm T3, E2 and T5, opening up HD2 wouldn't be a problem. Should have known HD2 components are really fragile...

The best topic ever Thanks, dude!
My Folio 100 suffered an accident and the LCD got cracked. A big part of the LCD is not working.
Other than that, the tablet is working properly, the touchscreen works, the tablet boots and you can launch applications and use them to some degree.
Is it possible to replace the screen? Where can I find a replacement LCD for this tablet? Would it be possible to replace it with a better quality LCD?
Im not sure you can do it yourself. You have to find a lcd that matches the connector used in the folio and uses the same driver, has the same size and resolution. On top of that if you open the folio you void your warrenty. Speaking of that, cant you get it fixed where you bought it?

Hi, this is my first post but i follow you from years
My i9100 fall down and since this moment i have the black screen, but the phone works (call, TOUCH PANEL, and all the other things). I would change the display, but there is no signal about lcd broken: glass is perfect, touch panel is perfect and lcd don't look like a broken one, but it's expensive and i want to be sure that it is broken. Are there some program that allow me to see hardware issue from the pc with usb, or i must buy the mhl adapter and try it to the tv?
sorry for my bad english and thanks for helps
Cliffs Notes version:
Broke the glass on my Rezound but the digitizer and LCD were working fine. While replacing the glass I broke the LCD, so I bought a replacement from ebay.
Now the new LCD will turn on to show the initial HTC screen and then it goes blank...no backlight or anything else on display. I can boot into hboot and fastboot. When I try to boot into recovery I get the blank screen. Did I get a bad LCD, or is there more to it than that? I managed to find the broken LCD and it has similar behavior, so I'm worried I may have broken something else on the board while replacing components

make sure the rainbow cable isnt pinched anywhere and that it's plugged in 100 completely, ive had this happen to me when i first started to take apart phones with the Inc. even if it's a slight angle it will not make a good enough contact.
Hi!
I have a PX3 unit with MCU HA 3.40 (not a dasaita one, maybe a clone) and it has 6.2 screen with a 800x480 resolution. I "got tired" of this screen, it is small, I am getting older , and I would like to replace it with a bigger one , 7 inch or 9 or 10.1 and with better resolution of course, 1024x600. I can made mods, I am just asking for some advise and sourses of knowledge which is plenty in this forum and thanks in advance for it!
I removed the front panel of the HU. It is connected to the main board with a ribbon. The front panel has an electronic sircuit and the lcd and touch screen is connected to it. I found that the lcd panel is 60 pins and the touch screen is 6 pins. On the back of the front panel there an electronic panel with the circuits and chips of the physical buttons (not touch buttons) and there is also a 40 pin connector (empty) and the lcd screen has a 2 pin cable with red and black color.
I saw some youtube videos of disassembling some new cheap car units with 1024x600 resolution, one with a 7 inch 40 pins ribbon and one with a 10.1 inch 60 pins ribbon and the 2 pins cable. So am thinking either of buying one of them and replace all the front panel or buy only the lcd and the touch panel and make a new "cover" for my car unit .... I don't bother with the physical buttons, I 'll find a way or modding them... But I have some questions:
1. Are these lcd panels and touch screens of the new cheap car units combatible with my unit?
2. Is my 40 pin connector working on MY unit or only the 60 pins one?
3. Is the 6 pin touch screen a "universal" common interface for these car units?
4. What is this 2 pin red/black cable? power for what?
I attach some fotos of my unit. Every suggestion is welcome!

Reply with an update if you sent ahead with the screen swap. I'm also curious if they are cross compatible? I have a 9inch 8227L Demo and the gps antenna wasn't working so the seller sent me the same model headunit but with a 10inch screen and upon hooking up the 10inch, Amp chip wasn't connected right or it was faulty. Anyways my plan now was to swap the 9inch working headunits screen with the 10inch. All the connections look the same and if I can swap out the board from the 9 and put it in the ten I will. I just haven't found to much info about it I can or not... Another idea I had was maybe try to disconnect the amp chip from the 9inch and solder it into the 10inch? Do you have any ideas if either of those ideas would work ?
Thanks in advance!
Have you tried to re-solder the pins on the amp?

No I've yet to try that. The reason being is because it looks as if the one pin that wasn't touching the board (or soldered incorrectly to begin with...) Shorted out and that pin/leg looks a little burnt now. Also it looks as if maybe possibly there wasn't enough Thermal Conductive paste too?? Just a guess though. ?
