Maybe the cable that connects touch to the mainboard or the touch-foil thing (that one with the grey lines) became torn (happened to me when I opened my phone not carefully and put force on the cable (i think it's called flatflex) by pulling out a piece that was under it without removing the cable first).

Did you changed to original one? After my screen broke I change touch three times. First two times touch didnt function properly (cheap chinese touch). Than I bought original touch with screen (from broken SP only with one small scracht for about 8 EUR) Work like a new.

I think i fooked my phone...

After replacing my touchscreen the phone wont boot, gets to the second splash and restarts. I have tried everythiong i can think of, MTTY, reflash, flash to 2k3 etc. anyone got any ideas?
Many thanks
(and yes i was using static band etc)
Yo bra
just curious did you try the old screen back in again of course as well and test?
i replaced it cause it's broken (i didnt replace the LCD, just the toucher digitiser thingy)
woohoo! it's stopped resetting, but the touchscreen still doesnt work (at least no crack this time )
Maybe touchscreen is not really compatible with the device?
There is also another posibility I don't want to share with U.... (bad one... rly bad)
the touchscreen is the right one (Sony not Toppolly), but i have no idea why it doesn't work. Tbh i'm just gonna give up and buy myself a G-smart.

Lower part of digitizer not working

Hi,
My friend gave me his broken G1(digitizer+screen).
I've bought new ones and replaced them.
Now i have a weird problem that the lower part of the digitizer is not responding, i cannot open the menu button or touch anything there.
but if i hold my finger for few seconds and then let go then it will open a "quick search".. like it is responding.
is it possible that i've messed something along the way or that the digitizer was not working from the factory?
Also was wondering if there is some program to calibrate?
Thanks
Anyone?
can't help you actually, but i hope this hint helps you:
the g1 has a capacitive touchscreen, it doesnt require a digitizer / calibrating...
but as i don't know how capacitive touchscreens work in detail i can't help you...
I have the same problem :S
I have seen posts about the lower part of the digitizer not working. I think your digitizer is defective. Try wiping and installing your rom again or If you can, see if you can disconnect the ribbon connecting the digitizer to the LCD and then connect it back to the LCD, restart your phone and If it still does not work then your digitizer is probably defective. Contact the seller and ask for a refund or replacement would be the best choice.
Ye I managed to fix it.
I opened and reconnected my phone probably 100 times :S
Oh well, I hope its fixed permanently and Iwon't have to open it again incase it drops out again :S
If you just recently bought the digitizer, i would suggest you ask for a replacement so that problem would not occur again.

[Q] Milestone touch screen problem???

Yesterday when i take my milestone out of my pocket I noticed that the Settings touch button(second from left) wasn't working, every other "bar" button was working fine, except that one. Then I noticed there's a vertical line, that goes from the Setting button to the top of the phone that doesn't work. It simply stopped working... Some1 Help me pliz. It' s a Software or Hardware problem, and if it's a Software problem this thing will solve my problem??

same with my phone, may be digitizer was broken
Are u using a custom Rom or the Original ? My touchscreen had a similar issue, and reflashing the ROM solved it. It took 2 flashes, but the issue is gone.
Dont know if yours is the same, but if the issue still remains, atleast it can confirmed that its a hardware issue and not a software one.

I have used CM6 on my phone, but when i got this issue, i made my phone back to 2.1. The problem is still standing.
uh oh. Looks like a Hardware issue then. U still might wanna take to the store and get it verified. Is it still under warranty ? Any possibility of an exchange ?

This may solve my problem??
Havent seen any such issues.. Thanks god..
it's similar to my problem, I had the back button through the top of the screen not working..
I have tried flashing, factory resets, and whatever I can do, but still no changed,, so I tried to ask the closest customer service and they said that it's the touchscreen panel must be thrown away to get the new one..
is it really true ?
please share this problem,,
thanks,,

Hi all!
I was having the same problem with the column of numbers 3, 6, 9 of dialpad. Looking for the solution in google, I have read that this problem is probably caused due to the moisture... so yesterday I turned of my milestone, removed the battery, SIM and SD cards and left it inside an enviromental chamber @ +70 celsius degress for 1 hour and guess what? Problem solved!
I hope that it works for anyone that are having the same problem!
Regards
Lucas

I have had good success with a combo of rice (inside a ziplock bag) to absorb humidity and/or a toaster over at the lowest bake setting.
Worked on MANY electronic devices over the years.
Sent from my Milestone using XDA Premium App
Same problem here. I've solved it by changing the digitizer (ebay 25 euros). Works fine now but in the mean time I change for a Desire HD... good by Milestone !
If you decide to change the digitizer, be patient, fixing th Milestone is not an user friendly task But if you take your time it's ok !
ive the same problem, and i believe that's because of moisture. because every time when its raining except the problem with right side of screen im not even able to use the phone touch screen doesn't work at all and the phone just does something by itself! this issue started with small vertical bar from right side of screen and it growing everyday now im not able to use right side of screen till home button.
i want to know do i have to replace touchscreen or i can fix it with something to absorb humidity?
thanks in advance

[Q] HTC One M7 Touchscreen Doesn't Work Partially On the NEW SCREEN

Hello guys! Saddly for me my touchscreen stopped working but the thing is that i bought a new screen assembly but i still have the same problem and the same spot doesnt work (on the digitzer, lcd works perfectly). I really dont know what to do i have tried to google my problem but people always solve there problem by replacing the screen and i did the samething and still nothing. I'm running the latest stock rom from at&t now but i have tried to flash viper rom and cleamrom, etc... but i have gotten the same result
i tought that it could be the digitzer connector on the motherboard but it looks new so i cant find the problem...
To be more specific the spot thats shown on the image does work but when i touch it, it shows that iam using 2 fingers when iam only using 1 its really anoying when i use the keyboard. When i touch that spot, the phone starts to select things arround the "dead" spot.
My apologies if i have made some dumb mistakes in the text, i'm from belgium so english isnt my mother laguage.
IF theres no liquid damage.
The phone was working just fine, then mysteriously stopped working in one spot. I would guess replace digitizer (aka glass) But if replacing glass has yielded the same result. Now it gets tricky. Now its either a board level issue or a problem with the Kernel interfacing with its hardware.
Since not a stock device and has been rooted with custom ROM its possible those software mods might have affected it.
My suggestion is do your best to go back to completely stock and hope for the best.

Thanks but iam already on stock i have used RUU to reset the phone, same result. And liqued damage is possible any idea what would help?
Or is it possible that the connector on the board is broken?
As you start to eliminate your possibilities the fixes become more difficult.
If your back on stock everything and still bad then its going back to board level stuff. Meaning the connector on the board or something along those lines.
If thats the case then the fix is near impossible.
Might want to get a good strong magnifying glass out and see what you can find.

Most likely a faulty digitizer, replace your lcd assy.

hi,
i don't think that can be repaired thru software. you need to replace the digitizer on that phone. and unfortunately, the lcd and digitizer is bonded, it's not easy to just replace the digitizer. you can look on ebay the replacement lcd complete with frame and back cover. the only problem you will encounter if you DIY it is the disassembly, you can watch youtube or check ifixit on how to disassemble the phone.

Most likely, but just in case remove the screen protector (if you use one) and test again.
