Getting Ghost Touches (Phantom Touches) - Asus Eee Pad Transformer Prime

Hello,
Long time owner of a TF201. Currently using KatKiss v28 and loving my old ass tablet! But about a month ago I started getting ghost touches and just this past few days it has got to the point where the tablet is unusable.
For a few weeks the ghost touches would go away if I just locked and unlocked the tab but now they are there constantly. Using a touch screen app I can see the ghost touch is only in one spot and is a constant steady touch.
So far I have tried rebooting and also the hard reset pin whole reset. I tried squeezing the tablet at the problem spot and cleaning it really good with alcohol swabs.
My question is what would be the next best step?
I don't mind opening it up and maybe resetting some cables or taping them to stop a short but I don't think I want to invest in a new screen or anything.
Any advice would be appreciated!

Update (self necro) (resurrection?) of my own thread
I managed to fix my dead zone! It has been fine for a few hours now. I will update again if it changes.
So eventually an entire strip or zone of my screen was unresponsive to touches. Using this video as guide I have managed to fix the dead zone completely.
I discharged the igniter device up and down the dead zone and it fixed the entire area! The screen now works as before with no phantom touches or dead zones!
It was a little unnerving discharging right to the screen of the tab but it didn't seem to damage it at all.

[Q] Touchscreen not responding

Hi folks
Just inherited a very worn out one year old Xperia X10 from my son. Been trying to resurrect it.
About 2 or 3 months ago the touchscreen started to become non-responsive occasionally. Admittedly, I didn't look at it for him at the time. Then he dropped it down the loo (think - hope! - there was only water in it at the time). We dried it out in the hotpress and it worked ok but still with intermittent touchscreen not working.
He got a Blackberry from Santa, so a couple of weeks ago I inherited the Xperia. The screen was cracked in several places and totally non-responsive. Rather than chuck it in the bin, I thought I'd try and fix it up. So I bought a new screen on ebay and the other night I dismantled it and fitted the new screen. Touchscreen is still totally non-responsive. There was a slight rust on the perforated metal plate at the back of the screen which I carefully cleaned with WD40. All the connections and circuits look ok. I've updated it successfully on both PC Companion and SEUS.. I've also tried flashing using instructions from this forum but cannot get it right (most flashtool symbols greyed out). I have a feeling that it's a simple problem but just can't get there. The screen display is fine, I can get the camera and the keyboard up using the buttons. But damned if I can get the touchscreen to work. I feel the problem harks back to when the screen was intermittent - it still worked after the water/screenbreak, but not that well.
Anybody got any ideas or should I bin it? (Can't seem to get any worthwhile advice on the WWW - happened upon this forum while searching and thought - "This is my MAN". (One suggestion I saw on the web was to try a new battery - can't see how this would make a difference, present battery working fine. Also, I wondered if the proximity sensor could be on all the time?)

[Q] Screen problem (not the classical screen bottom)

Hi,
I have a touch screen problem with seems like if the screen "feels" a non-existing touch so that when I actually touch it with my finger it activates pinch-zoom mode.
The problem appeared after I left a phone on a shelf switched off for about 1.5 month waiting for a new battery to arrive. When I switched it on with a new battery the mess started.
Tried the old battery, factory reset. The problem persists, sometimes right after boot, sometimes 1-2 min after boot.
From searching the forum I understand the most common problem with Hero screen it bottom freeze, but that's not my case and I couldn't find problems similar to mine.
Thanks for help in advance.

[Q] Screen flicker/dims/blacks out issue

Any help much appreciated....I have an issue with my screen flickering, dimming very faint and going black when i touch my screen. sometimes my screen will go black for long periods of time and phone is practically useless. This is not an issue of just a slight flicker on light colored screens that I have read other people describe. The screen does not always do this but is definitely getting more frequent. The flickering/dimming happens when I touch screen and especially when I touch it with more pressure. It also seems to be more sensitive on the bottom half of the screen.
I consider myself as the "scientific type" and have been testing many different scenarios trying to find a rhyme or reason to this happening. The only thing I have found is that if I keep my phone out of my pocket the problem seem to not happen. Then I can put my phone in my pocket for as little as 5 minutes and my screen could be messed up for hours. Everything else about phone seems to work great.
At first I was thinking this was a software issue but now I am leaning towards hardware? I am rooted, unlocked with s-on and cannot send back for warranty. I was running mean Rom for many versions and have also gone back to stock rom and stock kernel and experience same problem. Many reboots and clean installs too. I have also taken phone apart and reconnected all ribbon cables hoping there was a bad connection.
My Evo lte is only 4 months old and has never been dropped nor has it ever been wet. There are no scratches on screen and has been in otter box since the phone was brand new. I am running out of ideas and am I dire need for advice.
Thanks,
Mike

Unresponsive touch screen

Hello mates.
I've got some issue with my desire x touch screen. It is becoming unresponsive.
The whole thing started like 1 month ago. I've noticed that as my phone gets hotter (playing games, using internet) my touchscreen was slowly becoming unresponsive. Firstly I was unable to scroll down my notifications (only the narrow bar at the top was not working) and then it came to a random places of screen, so I couldn't even write sms message. The thing is that it is not unresponsive at all. When I press certain unresponsive area it finally detects the touch. I tried everything, from wiping my screen with a soft tissue through removing battery and sim and sd card to wiping dalvik and cache. I've noticed, that after night the problem was almost gone. And again, after using phone for some time issue occured again. I figured that flashing a new kernel might be a good solution. And it helped and I was happy.
Unfortunatelly, yesterday problem returned. But as you probably suppose - flashing kernel ain't helping. I've also tried other methods mentioned above, but the only thing what helps a bit is leaving the phone unused for like 1 hour or so.
Do u guys have any ideas, what can I do to repair it or to fix it? Any help will be strongly appreciated

I have a similar problem after replacing touch screen. I have found the source of the issue, it could be similar to yours.
My touch screen at the bottom was glued to the LCD in a short line and the adhesive was probably touching part of the LCD cable that goes underneath. I used a hair drier to warm it up and lift off the touch screen. That way there is no bad interaction between the touch screen and the LCD. Haven't had this problem since but my touch screen is unfortunately a bit lose this way. Even now, whenever I push the navigation part of the touch screen too hard, the problem comes back. I will need something to isolate the bottom part of the touch screen from touching the LCD. I will keep you updated if I find a final solution. In the meantime, it could be worth trying it on your phone too.
I think I will just get S-OFF, revert my phone to stock and give it back for warranty repair Anyone of you guys did this? Did 7 vibrations at boot void your warranty?
I'm thinking about warranty repair, cause my bro has the same phone, but full stock, not even rooted. And he got simmilar problem to me, but with less intensivity (it just comes and goes once in a while). Also recently I got this phantom touch problem (after enabling show touch in options I saw my phone is detecting some touches in specific areas) So I think warranty will be the only option :/

Redmi Note 3 screen unresponsive

Hi hoping someone can help. Had my phone around 3 weeks now and all was great until yesterday. The screen just stopped reaction to touch mainly on the right hand side but I don't think that this is a hardware issue and the screen works everywhere when rotated. I tried a factory reset and problem is still there. I have never rooted a phone in my life so keep it simple haha. Thanks in advance
Any help guys? How can I add a screen shot on here to show what firmware it is running?
I have not had this problem, but I did have a similar problem on another phone before where part of the screen went dead , I think it's related to moisture try putting the phone somewhere dry or blow a fan on it for a few hours see if the touch comes back.
if you have it in a case try removing it
