LCD and LCD Ribbons - MDA III, XDA III, PDA2k, 9090 General

are they separate? I brought my phone to the service center and they said that the LCD had to be replaced. The only problem with my phone is it turns white or the screen gets garbled when you slide the keyboard. Screen works perfectly, so if I'm not mistaken it is only the ribbon that is broken. If it is only the ribbon then are there available ribbons?

replaced screen, ribbon tore, now only vertical lines on screen

like the title says, i broke my screen, replaced it, it worked fine for a few days, then after pulling the face up and down so many times, the tape on the back of the screen created a little rip in the ribbon cable(stupid me!), so then there were vertical lines, i got my screen with a warranty, so i got another screen, the screen looks fine, ribbon cable is fine, but i still get vertical lines. think my video controller is messed up? i made sure the ribbon cable is firmly attached to the mobo and all, but still vertical lines.

[Q] G2 Screen Issue LCD Glass Digitizer

I bought a G2 with a broken glass Digitizer. I replaced the digitizer but the LCD screen was cracked as well. So i replace that too. After replacing the glass digitizer and lcd screen the phone would respond in certain areas. SOOO I took the phone apart once more and press the LCD against the Glass digitizer which help with some of the "dead spots" on the screen. But there are still some "dead" spots here and there. Is there anything i could do to have the Lcd screen stick to the digitizer so i don't have these issues. I love my G2 but its useless at points when the multi touch is not working properly.
You should have sent it back on warranty.
Removed "Void" sticker over one of the screws
I removed one of the stickers do you think they'll notice?
no, they'll send you another one as soon as they get the tracking no. from you.

[Q] LCD failure?? need help

Hi there,
for the past 2 days the screen on my evo will at random change colors to pink, purple, green, blue and if i press on the back of the phone it will change back to normal. basically If i put any pressure on the phone what so ever the screen will change to a different color. Does this sound like the LCD is failing?
I put a brand new LCD + Digitizer on it about 6 months ago as i bought the phone with a busted LCD.
edit* also i wanted to add that i just opened the phone up to inspect the ribbons and i do not see any kind of damage what so ever. and the motherboard is also only 6 months old as i replaced that due to the previous owner melting the board with a soldering iron.
Does this sound like the LCD is failing?
Click to expand...
Click to collapse
No, actually it sounds like it could be the lcd cable itself is loose. The only way to tell is to open it up, unplug the ribbon and plug it back in securely. If that fixes it, then it was the cable, if it doesnt, then its the lcd itself.
Thanks for the reply! I'll open the phone up again tonight and play with it and see what happens.

So I installed a brand new LCD + Digitizer and it seemed to be working for the first few moments and then went back to doing its weird color changing.
Even with the new screen if I squeeze on the phone or apply a gentle twisting motion to the phone I can eventually get the color looking normal, but once the pressure is off the phone the color goes back to being a dark pink / redish color. Also I do notice a new symptom, the 4 touch buttons at the bottom of the screen do not light up with this new digitizer.
What are the chances that the new lcd is junk? Or could this be a more serious issue like the logic board being damaged? Are their any methods that I can take to ruling out the board? I payed 259$ for a brand new board 6 months ago and if its bad this POS is retiring its life!

Desire disassemble now Display won't work

Hello,
I disassemble my Desire to replace the cover of it. The AMOLED display and the touch screen worked with no problems. I disassemble every part but had some problems by removing the touch screen so it was broken in one corner. I ignored it, replaced the cover, put all back together and attached connectors for display, keyboard and touchscreen. After that I start the phone but now I get only a black screen. I see nothing on the display but my phone starts because I feel the vibration and the lights of the buttons are glowing.
So, is there any option to fix that or is it now completly broken? I'm really sad because it worked with no problems a few hours ago and because of this cover replacement I have no video screen now.
On Ebay I can get a new AMOLED Display for 40$ (30-40€). Should I try this or is maybe the main PCB broken? The broken glass of the touch screen can not cause this problem, wouldn't it?
Greets,

just installed new motherboard, still need to glue screen, but display no workie

the touch screen does though, annoyingly so, I can myself making a phone call trying to get the screen to display. The contacts at the ribbon for the display are all good and intact, both sides, I know cuz I've ruined them accidentally twice on two motherboards so I'm very careful now, board was tested good before I bought it on ebay, connector fully seated and locked... are there other points on the motherboard that effect just the display? Any you guys in here get this deep in this phone? This is the worst phone to dismantle. How to troubleshoot touch screen good, but no display?
