New Digitzer not calibrated - Miscellaneous Android Development

I am currently working on my friends kids Nabi 2. The little boy threw it against the wall and cracked the glass and damaged the digitizer. I went ahead and ordered a new LCD, and an assembly for the front panel/glass/and digitizer. It also came with the LCD but was sold as not working on eBay. I removed the bad LCD and replaced it with the new one I got. Everything worked great. EXCEPT THE TOUCH SCREEN CALIBRATION IS WAY OFF! I really can't do anything on it. I tried a factory restore (from bootup)and nothing. I tried re searing the cables twice. I also removed the LCD and re installed it again. Nothing. I've looked for a calibration online and no dice. Is there a way around it? Please help. They are moving to Michigan this Sunday!

What is the black stuff between lcd and digitizer

I was wondering what the black stuff between the lcd and digitizer is and where do I get it? My wife and son both broke their digitizers so I decided to replace them. The first phone I did was my wife's and I think I might have removed too much of the black adhesive because the digitizer keeps lifting up allowing dust to get trapped in between. I learned from my first attempt and myy son's went much better and is working perfectly.

Replacement Screen Problem

I cracked my screen a few months back, and right after it happened I bought a new digitizer to replace the cracked one. The install didnt go very well, since the tape used to adhere the digitizer to the LCD got mangled during removal of the original digitizer. Dust ended up getting between the LCD and Digitizer etc. One other problem I ran into was that the LED's that are supposed to illuminate the home/menu/back/find buttons were now shinning up into the screen and washing it out.
Anyways I got fed up with the dust and bought a new fully assembled screen/digitizer off ebay. I installed it last night and everything is great except that the lights are still shinning up through the glass and washing out the lower inch of the screen. I dont see why this would happen as there is really only one way to put it all back together.
Any insight as to how to get the lights to stop doing this?
Thanks!

[Q] Repairing a damaged screen

First, the story:
I dropped my phone and broke the screen. The screen is always black now, but from the sounds the phone makes, it sounds like it is still working.
This place has instructions for replacing the touch screen digitizer and the LCD; they also sell these replacement parts (for $40 and $35 respectively), (I had to obfuscate the URL to post this, so replace the underscores with periods):
www_repairsuniverse_com/htc-mytouch-4g-slide-screen-repair-take-apart_html
I'm not quite ready to move on to a new phone yet, so I am planning on trying to fix this myself. I guess my other option is to see how much it would cost for TMobile to fix it for me, but I am guessing that they want too much. My phone is rooted (s-off) and running a Bulletproof 1.1 image.
Now, my questions:
Has anyone here successfully been through this process? Any advice would be greatly appreciated.
I have not yet attempted to disassemble the device to futher assess the damage, so I do not know exactly what is broken, although the glass is certainly broken, is this what is referred to as the "touch screen digitizer"?
LCD is the actual display. Digitizer is the glass that sits on top of the screen (the part you touch)
If your LCD is broken, the picture will be messed up

Replaced the glass (digitizer) without issue. returned the phone to t-mo since prior to that it was having an issue with the hardware camera button being stuck always on. So long as you're patient, technical, and have a steady hand, do it, it's fine, just follow-the step-by-steps, and keep your screws and parts seperated at each step
I ordered a new LCD and digitizer, and will probably have some time to do the repair mid-late next week.
I went with the Sony version of the LCD based upon discussion in the following thread (in the 3rd post iynnoji says they tried a Hitachi LCD but it did not work):
http://forum.xda-developers.com/showthread.php?t=1526595
It would be nice to know if the Hitachi LCD is incompatible, or if iynnoji had a bad component or some other issue.
Anyway, thanks for the feedback gtmaster and eclipsed. I'll update this thread after I attempt the repair. I have to admit, I'm sort of glad I broke my phone, since learning to fix new things is such an enjoyable process. Hopefully I'm still happy about this process after I finish the repair and attempt to power the device on .
Yay! The repair was successful! Not having a cell phone really made me aware of how useful one is. Next time I upgrade I'll keep my old device around as a backup.
So some notes:
The screen assembly was really difficult to remove, due to the large amount of adhesive. When I took it off, the LCD split in two, with half attached to the screen assy and the other attached to the adhesive. Luckly I was intending on replacing the LCD anyway. Anyone else performing a screen or LCD repair should beware that this is a difficult step, and will take time and care.
The Sony LCD (P/N 60H00523) works fine with our device. As I previously mentioned, it would be nice to know if the Hitachi LCD (P/N 60H00512) works, as its $15 cheaper.
I wasn't careful enough when placing the LCD on the digitizer, and managed to a few dust particles sandwiched in there. Not a big deal, but if I were to do it again I'd check my work before assembling the rest of the phone.
I used the adhesive paper sold at repairs universe around the edges of the digitizer and put the phone in the oven @ 170 F for 5 minutes after assembly, then waited 10 minutes before using it. Everything seems solid.
Again, thanks all for the help.

[Q] Screen Replacement

I managed to break the screen on my Optimus 3d last night, not sure if it was dropped or ran over. I found it face down in my driveway this morning and to my horror when I flipped it over the screen was completely smashed, however the phone is still working fine, minus the never ending ghost call issue.
What make the situation worse is Rogers just sent me out a replacement phone yesterday and I have to send this one back, in the next couple days.
So I called a repair centre and they wanted $190 to repair the phone, and stated they would need to replace the LCD and the glass screen. I know there is nothing wrong with the LCD screen, phone functions and all colours are good, just has broken glass.
My question is, can I repair just the glass without replacing the LCD? I have found the screen for around $30 on ebay. Based on watching the how to on youtube it doesn't look like too difficult of a job.
me too i have broke my glass of my phone and they said like your prize to replace thre glass but in my country crunncy and the screen work perfectly I don't know why they want to change the screen too it's annoying

If your LCD is working you only need the digitizer replaced (phone front + touch screen) which costs you around 20/30$ http://www.ebay.com/itm/Replacement...080?pt=LH_DefaultDomain_0&hash=item1c2d78e968 .
My touchscreen was broken (randomly pressing things on the screen) and I think the 2nd hand shop I got it from only replaced the digitizer I think based on the small dust I see on my screen.
This only works if your LCD doesn't show blurry or (partially) black (damaged).

After screen replacement touchscreen is not working

I changed screen assembly to my boys Honor 8. All went well.
Not so nice job BTW.
I tried that the screen was working but didnt tested the touch. I reassembled it and noticed that the touch is not regonized.
Does somebody have any clue or is the assembly just broken? :crying:
Likely you didn't connect the digitizer, or the digitizer is broken. Touch won't work without digitizer. I don't know how to fix it, you may have to look it up, maybe Ifixit has a guide. You may need to buy another digitizer for Honor 8.
Problem solved. I detached screen again. In bottom of the screen there was digitizer connector. It looked OKAY but I disconnected it and but it back firmly. Touch started to work. Yeah baby ??
Nice. Was I of any help?
