[Q] Bad colors after screen replacement - Nexus 7 Q&A, Help & Troubleshooting

Hi there!
I've replaced the screen (LCD+DIGITIZER) of my N7 LTE with the video on youtube (cannot post link sorry)
After rebooting the N7 i've got bad colors the main color seems CYAN and the screen seems splitted in the areas one of the two being more dark and red-less.
The digitizer seems fine work with no problem, reopening the device and checking all cable connection as not solved my problem.
There is anyone with suggestion on what can be the problem?
Thanks Bye
Rob

Dropped my Wizard - White screen

Hi to everyone.
I dropped my wizard and lcd broke so I bought a new one and put it on. The problem is that although it takes phone calls and it syncs to pc, the screen is always white with nothing written..only a white screen. I do not know whether another problem occured besides the broken lcd. I tried to disassemble and reassemble it again but with no success. Any help please?
Hi, If my understanding is correct there are 2 versions of LCD for the Wizard. Are you sure that you have the right one? I'm sorry that I am unable to offer any further advice except to say that if the phone 'phones' and 'syncs' the basics must be working. Also the white screen means that the backlight is working - the problem is the LCD drive. Perhaps worth checking with your replacement supplier that they sent you the correct part?
Good luck!

my touch shows only white screen

hay from today morning my htc touch shows a white screen and a crack on the bottom corner of the screen.i am sure that it dint fell down.
then what may be the problem?
anyone knows pls tell me...
white screen?
When you turn on your phone, there is no smart mobility.
Crack?
Is that an LCD problem?
i have the same problem with the WHITE SCREEN. bought my ELF 3450 second hand over the net. i am from the Philippines by the way and HTC units are not yet very common here and also the parts/accessories. it worked fine for about 3 months with minor problems such as Auto-Restart/Auto Power On/OFf which was solved using the "plastic on the OMAP chip method" - tnx for the forum for the info by the way and charging problems which was also solved by buying me a aftermarket charger. but recently the problem of AUTO OFF occurred again until it did not work at all. so, i tried to check the Plastic over my chip but to no avail the fone was dead. so, i decided to head to one of our local cellphone repair shops and have my OMAP heated thinking that maybe there are just contact points inside who became loose. when we tried to power on it was good for a few minutes then i noticed the screen went darker and darker and then it was all WHITE. we restarted it but it's just WHITE. tried to send messages and call it but there is no response from the fone. i'm afraid i toast it bad or may be it's just the LCD who got toasted, i am clueless.
CAN SOMEBODY PLEASE HELP ME WITHMY PROBLEM. CAN I GIVE LIFE BACK TO MY ELF? WHAT'S THE CHEAPEST & BEST SOLUTION TO THIS? THANX ...
Generally white screen problem are caused by defects in flex connecting the LCD to the mainboard or the connector itself. Try to disconnect and reconnect the LCD, if doesn't work - replace the LCD.

You warmed the OMAP? Interesting....
This problem sounds really complicated.
And im quite surprised of your 'warming' method.
I've had the exact same problem combined with the fact that my touch was resetting constantly. I was about a minute away from throwing it out of the window when I tried the plastic-piece-on-omap processor-technique described in one of the threads here. It solved the rebooting problem, but not the white screen issue. After a very frustrating couple of days where the screen started to blink and shake and then eventually turned to white alltogether, I lowered my brightness to the second stop from start, and since then I haven't experienced the white screen anymore. I believe it is heatrelated.
Whilst not being a full solution to the problem, at least it renders the phone usable.
Hope this helps anyone.
Heating the device very seldomly solves anything, but causes more problems that you originally started with.
iam using htc touch (p 3450) for nearly 18 months . (bought & using it in india ) my hand set fell two times in water and about 15 times fell on the floor (from shirt pocket) . still its working fine .
and iam using "opera mini " for browsing the internet . for some sites iam using "opera mobile " . when iam on opera mini , continueously for long ours , suddenly it turns white . never come to normal screen unless restarted . but it happens sometimes , may be because of memory or heating up of some H/W .
Hi hotchamo,
my htc touch elf hat a similary issue, and my father just "wringed" it gently until the white screen disappeared. You should try it carefully, since it may help and it won't harm. Just take in in both hands and turn them in the opposite direction, so that the case gets slightly twisted.
If that doesn't help you should open it and check the LCD flat cable connector...
Best regards,
scheutak
Again - flex connector problem. 'Wringing' it gently will eventually result in your LCD cracking, by all means - go for it, it will solve your white screen problem. Permanently.

[Q] HTC Trophy LCD problems, please help!

Ok, I recently fell on my HTC Trophy(Verizon Version), cracking my screen. Before that happened I had a weird LCD problem that came out of nowhere. I replaced both the touch digitizer and LCD screen successfully and turned it on. It worked perfectly. No screen defects ect. Then I later turned it on and the same problem happened! Here are some pics to show you. Do I need A new LCD (oh god) or can I fix it? any answers will be much appreciated. Also, the auto thread search thing is wonderful, great idea!
EDIT:I can't see the spots when the LCD is off.
When I was doing a laptop LCD replacement screen, I had accidentally left a bubble and was so annoyed that it would not display where the bubbles were.
However after 2 weeks the bubbles just disappeared and the laptop's LCD screen was working correctly.
You might want to wait a little longer and see if the heat will evaporate it?
(Good luck)

Non-Rooted Screen Graphics Issue, Help?

Recently, my mom's tf developed a weird screen effect, everything turns this reddish orange color. Not all pixels, but some of them, like a shading. The only thing she said that changed was that her weather wall-paper updated, but the issue turns up on all screens. Help?
After looking around more, it appears as if it's mostly on picutres that the strange coloring appears.
Also, the TF is completely stock, with the latest update.
If you could post pictures that would be helpfull but most of these issues are caused by drops loosening the digitizer cable so you may have to send it in to get fixed
