Cracked screen (video was fully functional, digitizer didn't work) replaced. Upon boot the right half of the screen was full red and the left was black. The"Google" splash screen looked normal, The 4.4 swirling colored dots behaved normally with all colors showing in either half. After boot the screen displayed oddly on the right half, with some edges flickering red, some colors appeared nearly normal. I could go on but I think this is good description.
All other functions work well, including the digitizer.
I reseated the tiny video flex cable and the problem persists.
I ordered another video flex.
Has anyone encountered a similar problem? Did the video flex fix it?
Fixed!

my htc hermes (herm100) does the occasional white screen here and there, but i dropped it (like a foot away from the floor) and it almost always white screens, the phone will come on, the ATT logo (like the bios thing) will load up and everything, but as soon as its about to play the 3g animation, the screen fades to white, but everything works, the 3g sound plays, the screen responds to touch, etc. the screen also displays perfectly when i start to do a hard reset, the screen comes up to press r and all that, then space to boot, then the screen goes white again. i've taken the phone apart, checked everything out, made sure the ribbon cables and such were set properly, everything. If this helps, my camera had stopped working the night before...when i would click the camera button or started it from programs, it would say somethin along the lines of "the camera could not be started. initialization of camera failed" and i was actually gunna be asking about that right now til it uber white screened. Any help is appreciated.
White screen
Hi i'm also having the same problem with my hermes 300, Dropped off the back of the bed onto skirting board, about 1 1/2 feet. Started to white screen soon after this. Like you say when you format it the screen is fine until it gets past the first boot screen then slowly fades to white. Have heard stories about the ribbon cable to the navigation on the front. any help apreciated
Update: Took Hermes apart nad reseated the d-pad ribbon, everything seems ok. Thanks to Mike channon for the Disassembly manuals. Hope this helps other people.
So, I guess I screwed with something on my phone, but my display now shows "color bleeding" mostly when i open the phone up in horizontal mode. Would this be a problem with the flex cable? if so, just replacing that cable should fix the problem right?
I am able to disassemble the whole phone no problem.
I am experiencing the exact same issue, its bloody annoying.
I'm fairly certain it is the ribbon, but I wouldn't know where to get a new one, so havn't tried swapping it yet.
Did try disassembling and cleaning it out a bit though, no luck

Could you post a picture of what you're talking about?
Sadly enough, I do not have a camera other than the one on my dz... a screenshot wouldn't do anything since it just looks fine.. but it's something with the physical hardware part. I'll see if I can borrow a friend's camera when it happens again, but essentially the red and blue colors look like it's splotched in different parts and sometimes it even "pulsates"
it doesn't do it in vertical mode, but in horizontal mode.. it appears instantly.
Thanks to someone in another post that led me to the amazon link for the ribbon cable.. the phone now has no color bleed. Woohoo!

It works great and looks exactly like the original.
I'm experiencing a slight color disfiguration. I traded my girlfriend my phone for a few days and when i got it back, the bottom half has a yellowish tint. Is the flex ribbon the reason why it's like this?
is it the same tint whether or not you're in vertical or horizontal (keyboard open) mode?
if so it might be your flex cable or it might be the actual screen itself.
Yeah, the yellow (and now with blue) tint is in both modes. lower half of both sides (vertical and horizontal)
wait, does the tint change on the screen? as in does the tint stay in the bottom half of the vertical screen and stays in the right half in horizontal? or does it shift so that it goes to the bottom half in horizontal? if it stays in the same physical space in both modes, then it might be the screen itself, but if it shifts.. it's most probably the flex cable.
yeah, it shifts. but now the blue and yellow lines is throughout the screen. initially, i thought it was a ROM thing, so i changed it to see it in a different rom.
sounds like a flex cable problem. I can't guarantee it since it's one of those "replace it and see if it works" deal.
Had to buy a screen replacement for my Nexus 4.
After the replacement i can see one distinct vertical line to the left. It's purple on white background.
I can also see it in recovery mode, but when i take a screenshot it doesn't show on the picture.
Is this a malfunction of the new screen, or did i mess anything up?
The screen i ordered missed the frame so i had to buy a front frame seperately and glue the screen to this.
I used this guide:
http://www.youtube.com/watch?v=YSe1I0MlpLI
everything went well, except one thing; when i connected the flex cable to the frame (check @ 23:19) i removed the little blue transparent plastic sticker, i thought it was a protective sticker cause my screen was new.. (the guide also said i had to remove a sticker if it was new)
but i found out right after it was actually supposed to be there.. i sticked it back on, though i didnt take care to align it 100%,.
This was the only thing i did sloppy..
could this cause the vertical line? think i'm going to open it up again and try set it straight if the line annoys me too much, but does anyone know what the purpose of this little blue sticker is? it looks like plastic so i thought it weird that this should lie between a cable and the frame?
anyone know?
Not sure about the blue sticker but it's either a defective screen, or more likely a badly seated flex cable.
I haven't had to change a screen since my old Nokia n95. That had something similar. Though mine was a line of purple and the backlight would only come on if I squeezed the phone.
Taking the screen back off, removing and reseating the ribbon cable fixed this issue.
I'd say it's likely to be the cable because the colours are sent as rgb values.
In your case if your only getting red and blue to x row on the screen then that will appear as purple.
I'd be less likely to think that it's a screen problem because either the whole row would be black, or there would be specific pixels that would be missing an rgb and not the entire row

Hi everyone i have one problem.
I have zopo c2, chinese mtk6589 device with 5" full hd display. Few days ago i dropped it and it landed directly on front screen. Vertical white lines started to appear and everything was covered with ghosts as i was swiping or opening apps. Today i spotted there are no more vertical lines but my screen is still kinda of blurry. Should i replace LCD or is it possible that some cable disconnected or maybe something else? Any help is appreciated.
EDIT: Vertical lines and ghosting returned when i charged battery
I just replaced the lcd / digitizer and now only see colored lines.The screen has a vertical line down the middle, usually the left side is brighter and has blue and yellow horizontal lines usually going about halfway down, the right side has pink and yellow lines. After a few seconds the colors dim and the screen ends up grey/white on the left and dark on the right with a darker border around the whole thing. When booting up there is usually a larger patch of solid color that shifts a bit before fading. I can't open it back up until tomorrow or the weekend. Does it sound more like I damaged the flex connector or received a bad screen? By doing some blind touching I can tell via audio that the touch screen is working. Any advice would be appreciated.

just open the device again and check whether you have connected the display(the clamps) properly to the board... i had fixed a clamp loosely and i had the same issue (weird layers of color on screen). i opened the device again, fixed every flex cable perfectly to the board(found one fixed loose) and it worked....
I'm going to assume it was the little LCD flex cable. After removing it and plugging it back in, both the old and new screens are both completely blank.
The new cable fixed the screen issue.
