[Q] P500 touch screen problem when connected to USB - Optimus One, P500, V General

Hi
i have search many site but there seems to be no solution to my problem.
i just bought a LG P500. there was no problem on my touch screen if i use my travel adapter. but if i connect my phone to a computer, the screen seems to get messed up. like when I'm typing the keyboard just automatically types another letter. please help thank you

The problem is not in the phone and power in your computer is not filtered, you probably have a damaged capacitor.

htc touch plus digitizer problem

Touch Dual digitizer
Hi Saliml2
Not convinced it is a software issue. My digitizer on T-Mobile Touch Plus did the same thing. It stated behaving erratically and then stopped responding altogether. I replaced the digitizer (via eBay) and it work for a few days and then stopped again.
I have read around the internet and have tried several ROM updates etc (currently running a WM 6.5.5 found in other area of this forum) but this has not solved the problem.
It seem to be an alignment issue - i.e. screen alignment is outside the screen area, but there seems to be no way of getting it back. Could be a fault on the phone mainboard (?) but there doesn't seem to be any info around apart from sending it to HTC for repair (not viable as the phone value negates this)
My phone is still not working, I might try opening it up again and reseating the digitizer cable but have done this twice already.
Have you try change the flex cable?
I had one to, with the same problem, and after changing the flex everything was ok...
Good luck!
Hi Amokh Just to clarify, what is the flex cable? The digitizer has a cable already attached to it that plugs in to a zif connector on the mainboard - I assume that this controls the data flow for the digitizer.
Any help would be appreciated.

Flex cable, i was mean the cable between the mainboard and the lcd block, you can see it in the previous link, picture 20. Have you try it to change?
hello guys how did you manage to put the digitizer cable in place mine doesn t seem to get in place do i need something to hold the connector in place???

[Q] can i use my NT while usb is plugged in

Hi,
i have a NT , when i plug in the cable to my pc it shows he usual USB mode.
is there anyway to have it in usb mode but be able to use the tablet at the same time ? in other words get rid of the damn pop up and let me use it while its in usb and charging mode ?
thanks
you could try disabling automount... maybe the USB window is triggered when the SD is mounted for computer use.
That is absolutely correct. If you don't know where to find automount, it is accessible through the nt hidden settings app.
ive also been seeing a weird issue , ive done that in the past , but when my tablet is connected to power / computer usb cable to any power source my touch screen is funky , when im on the lock screen i can do stuff , i can pull the bar over to almost get it to unlock but when and if it does its funky , i just kicked it out off of auto mount and i have what i want except touch screen is not actually working , if i unplug it from the cable the screen works ,
any ideas ?
You could also try "ejecting" the device. That might put it in charge state and allow you to continue using the device.

I haven't noticed the "funky" screen on my NT, but have experienced it on smartphones in the past and it was associated with a noisy charger. Try using different chargers and see if the problem gets better or worse.
ah yes you have a valid point i have two NT's one for me and one for my gf hers blew a charger and we had to have B&N replace the usb port receptacle already , had it less than three weeks. I will try it with her usb cable and see what i get as they changed the whole assembly and if it does not occur with her new cable i will get them to exchange it before the 1st ..

[Q] Problem with my phone

Hey!
I have a strange problem. I can get my phone to start first by taking out the battery, hooking it up with pc or ac adapter and then it turns on. Even if I disconnect with the usb or ac its still working. Why cant I turn it on normally.
please do not post multiple threads. list all your problems in one thread. Do not open a new thread.
How old is the phone, it sounds like you may have hardware issues.

Bust Your Screen?

So I fell on the ground with the phone hanging on a neckband around my neck at the time of the fall; screen is busted... Let me remind you phone was NOT rooted yet (I bought it the night before, didn't get to it YET), with a trick found on YouTUBE connecting an OTG USB adapter to the phone and connecting any USB mouse to this OTG adapter, then this broken screen will have a little cursor/arrow light up;
Obviously, after that you can do whatever with a cursor coming up on this broken screen and with normal clicks you are all set...
But now is another problem......
In order for me to be able to take a full backup of that broken LG and to be able to load it on to this one, I would need to have the phone ALSO plugged in with my PC at one point of time.... now here is a dilemma... mouse is already there.
And I’m %100 sure that there has to be a workaround for this situation. Maybe there is an app in store that can do this for you? I can’t be the first to bust my screen, right?
Can't find a link for my G3, but this very simular. http://podfob.com/products/samsung-galaxy-s6-podfob
Thanx folks
P.S. Later tonight I'll be getting my new LG replacment phone. So please, give me your advice??

SGP512 faulty screen?

Hello and good day.
I wondering if anyone here knows the Xperia Z2 Tablet well enough to help me proceed to the next step in getting my xperia z2 tablet back in working order.
A little history; I used the tablet on/off when I first bought it, then life took over and I had no time or use for the tablet. Now with a new job starting in 2 weeks time, I could very much do with getting the tablet to work.
I thought the tablet was in some sort of Sleep of Death but it appears that was not the case; I originally tried all the different button combinations, letting it discharge and recharge, used PC Companion to repair, Used Flashtools to repair.
Now, the strange bits; the tablet won't respond to button presses UNLESS I have the micro usb cable plugged in either by charging or connected to a PC/Laptop; whilst connected to a charger it will do the 3 vibrations/led routine. when connected to PC/Laptop it will pretty instantly go in to fastboot mode. and this is the strange part, reboot the device in to system (I also have to quickly remove the USB cable) and can hear it boot up.
all that happens with NOTHING on the screen.
So I had an idea; I attached an MHL cable. Lo and behold I have a picture on my TV, but still nothing on the tablet.
So does any one know where to go from here? could it be a lose connection to the screen??
Seems like a faulty logic/mother board
just need to find a source..
