[Q] Horizontal black stripes across screen

I got my TF300T yesterday.
The first thing I did was update the firmware as the device strongly suggested I did. That means I don't know if the problem I have is related to the update or not.
Problem : on waking up (NOT on turning on), on random I will see thick black stripes across the screen (see pic), they stay on upon unlocking the screen, they stay on when going portrait/landscape, usually I will have to wait with the screen off for a little while and the problem disappears but it is nonetheless a fracking annoyance.
I manually upgraded the firmware to .29 (turned out it was the one already on it) without any change. Going through several fora, I saw that it is a known problem, experienced by others, with no official fix, but for some the problem appeared immediately after upgrading to ICS, suggesting the issue is software. However, no word of this problem appears on this forum, suggesting that the problem could be simply a defective device.
My question is : did I get a dud ? In other words, should I return it, or should I wait for a firmware update that may one day solve the problem ?
Any suggestion is welcome, thanks in advance.
E.

definitely return it, i don't think there's a fix for this.

Ok, thanks. Anyone else shares that opinion ? i.e. has every one here updated to .29 without any problem like the one described here ?
Thanks.

I'd try a cold boot (is that equivalent to a dalvik cache cleansing?).
(cold boot: hold power until it reboots. While still holding power when it's rebooting (the screen goes black) immediately press and hold volume down aswell. Hold both buttons until you see some text in the top left corner (it should be quick). Then RELEASE both buttons and wait).
Looks kind of bad, though.

Tried that. Failed :sad:
Happy I bought it from a store, guess I'll return it tomorrow.

Ok, I returned it today, got a new one in 10 minutes, they even replaced the screen shield that I had already installed on the faulty device.
So far, no sign of those black stripes, but I have been putting off pushing the update (currently .14). Will report after that if stripes reappear.
E.
Okay, it's been a week now, haven't heard of those stripes again on my new transformer. Definitely was hardware. thanks guys.

Is your phone in warranty?

can you give us some basic information? such like rom & kernel version, wether you rooted and ade using cputuningtools or something like that.
if you are under stock rom(original samsung & all further updates over kies) and u have done nothing unnormally so far i would recommend use the warranty too; )

thanks guys
i have not rooted or changed the stock rom
i only factory reset it when the problem started
i just discovered that when i plug in the charger the touch screen works normally but does not respond to touch when not charging

I had the same issue. I got my touch panel replaced by the Samsung guys. That's why I was asking whether your phone is under warranty or not.

Here we go, this proves this has nothing to with CM9, this guy is on stock.
Many people are blaming CM9 for this and claiming it caused the problem.
It's a hardware defect.

Agree. :good:
I'll wait for a few weeks or till the phone is usable for the kernel 3.0. :fingers-crossed:
If not then no other option but create a Rs.5000 hole in my pocket. :crying:

Same case with me... Bought the i9003 March 2011.
I'm on DDKP3 and around the same time as the OP, my touchscreen started to act strange... responsive only when charger is plugged in. Tried factory reset, but problem came back after some hours!
If this is a product-wide issue, then I guess sammy should replace it for free, even if it's out of warranty... too busy to go to the nearest service cenrter, will check later.
Till then, please keep me updated how it goes for you.
---------- Post added at 02:31 PM ---------- Previous post was at 02:24 PM ----------
Just wondering, if a reflash of DDKP3 via ODIN or any custom ROM would solve the issue... please suggest.

I guess the sensitivity settings (or something like that) has changed without you knowing. Don't know if it is the same as s2 but in s2, sensitivity of the phone not plugged in the charger and plugged in has different settings. So maybe the settings for it in your case (unplugged) has changed but not on the plugged in settings. It's all in the kernel btw.

Maybe asking a kernel dev if the values changed or what not. If i'm correct then it's a software problem, if not then maybe a hardware problem.

Same problem!!!
It happened last week when my phone surprisingly started showing this problem. After unlocking the phone the screen becomes unresponsive. In my case it is just 1-2 secs after unlocking the phone.
It lasted for a day, I tried flashing different ROMs. I was on XXKPE when it happened. And than suddenly my phone started working fine until yesterday when this thing again happened and the problem still persists (I am still on KPE). I dont know what to do.
I think it can be some software problem as the screen and touch keys do work for some time before becoming unresponsive and even the logcat shows no problems for the touch screen. I am going to try more ROMs now. Will keep you posted.

Possible solution !!!
Friends, I think I found a possible solution for this issue. Though it seems to work for me... I have to keep the phone under observation for some days until I can say it's the final solution.
A similar thread: http://forum.xda-developers.com/showthread.php?t=1695149
The possible cause for the touch screen going unresponsive seems not to be a hardware/software glitch; but environmental issue! And it doesn't depend on the ROM your'e running.
I noticed that most people from India having this issue say that this problem started in June, when the rainy season starts and it gets humid and damp.
In fact my phone showed this issue when it had rained for the last 2 days and it was very damp and humid inside the house.
You can do the following:
1. Take out the back cover, memory card, SIM and battery.
2. Place the backside of the phone near a hot air source (on top of a running CRT TV/monitor, hairdryer, laptop fan vent) for sometime.
3. Reassemble and check if the problem has gone away.
Do not panic if the handset gets a bit hot in the process!
In my case, I left it on the top grille of a CRT TV for a day which ran for 8hrs.
Do let me know if this works for you...

Flashing the ROM does not solve the problem

Thanks to agnivo007.
I guess the climate is the only reason. I used his method to heat up my phone a little bit by charging it enough. Than it started working fine. No problems since then. Lets see.

But changing the panel solves the issue..
The kernel won't reset itself if you change the screen.

[Q] Desire S broken? Buttons sometimes don't work

Hello!
A few days ago my desire s started acting very weird. Sometimes the four buttons don't work (home, back, etc.) and sometimes my finger gestures aren't recognised. For example if I want to call somebody and then click on the home button my device thinks I pressed on the call button instead. Or if I am in some menu and I click on some of the four buttons, my desire s thinks I pressed the display somewhere else on the screen. Sometimes it helps if I turn the display off and then immediately on. But after a few clicks the same behaviour again.
I wanted to install a custom rom anyway, so I did a full wipe and installed Fallout. But nothing changed. Do you think my device is broken?

Ive had this top my screen was replaced under warranty mine was stick at the time

Your phone has somehow been exposed to high temperatures?

Not that I am aware of. Though these things happened when I was out in the garden playing with my phone while the weather was pretty hot (about 30 degrees). But I don't think that you mean that with high temperatures, do you?

Excessive heat can lead to detachment of the adhesive that is bonded touchscreen, it's not making edge contact. It happened to my ex HTC Hero on a sunny day (the phone was black)

It happened here sometimes with gingerbread stock while on *charging*! Only when charging. It's not happening on ICS RUU update.

I had the same problem a fortnight to a week back... exactly as OP describes (phone 6 months old from new). I've factory reset and changed ROMs, the problem remains.
But since 4 days now, my phone has become completely unusable.
The back and menu touch buttons don't work at all now. And some area's of the screen are dead, and brown coloured.
It's a PITA every time I have to type anything as my keyboard keys don't work at all (and other area's). Then, randomly, after 2-10 seconds, none of the keys or phone touchscreen will work until I off->on the screen.
Anyone please any idea of a fix (to me, it looks like hardware)?
If not, anyone ANY idea how to add a back button somehow? Or even assign the search button the back button function?
I desperately need the back button working. TIA!

I have exactly the same problem with my Desire S (stock ICS). Anybody of you solved this?
Thanks.

Dead tf300t after update

Hi Xdaers
I'm sorry if this has been posted already, I tried searching without finding anything that worked.
I was using my TF300T last wednesday and i got a notification telling me of a system update, so i accepted the update.
After the update was applied the device booted up fine and i continued to use it, at the end of the day i put the device to sleep.
The following day i went to wake it up and nothing happened. My first thoughts was the battery died so i charged it until the light went green on both the pad & dock, Still no response. PLEASE HELP ITS OUT OF WARRANTY.
I have tried holding POWER, POWER & VOL-, POWER & VOL+, RESET BUTTON.
I also tried connecting it to my pc, it failed to detect the device.
I dont know what else to try. :crying:

What could have broken it, all i did was leave it over night.
If i put my ear on the top left of the back i can hear a very faint noise when pressing the power button, like my nexus 7 does just before the screen comes on.

If its just the screen you can always try hooking up a HDMI to a TV and see if you get anything. Just to make sure did you make sure to hold down the power button long enough? Sometimes you do have to hold it down for quite a bit for something to show up.

I have had it connected to the TV with no picture. I held the power button for at least 5-10 minutes. I've even removed & replaced the battery and tried holding power, no look there. I did find something interesting when I removed the back tho (bare in mind this device was brand new and has never been opened before) I found 4 warranty sticker all broken and finger prints fused onto the copper heatsink.

Tell me about it I'm going to be speaking to training standards as I was sold it as "brand new" followed by speaking to the shop I got it from telling them they broke the sale of goods act 1979 (selling a refurbished unit as pristine). Hopefully I will get a new device.

The same happened to me today, I used it normally and the screen just froze and I reset it only asus logo and stands. turn it off and will not start black screen and that's it. then I opened it and I see finger prints fused on to the chopper. Horrible ...

So just a quick update I just got back from my holiday and thought I'd try turn it on, and as if by magic it booted as normal.
Now the only issues I have is random reboots.
It seems to restart after a few minutes when I touch the screen. Is it possible to revert to ICS without root. I managed to do it before just by copying the update file from the Asus website on to the SD card. Will that work when going from 4.2 to 4.1???

AFAIK you can't go back to ICS once the tab is upgraded to JB. See this thread. However, you can go back and forth between 4.2 and 4.1. Hope that answers your question.

Nexus 5 Black Screen, But Still Working

So my Nexus 5 (a couple months ago) has started to just randomly go black. I get notifications and stuff, and the backlight but no display. Not sure what to do or what part to replace. Would flashing/rooting help at all?

Appears to be a hardware problem.
Was the phone every dropped or exposed to water/moisture? Possible loose connection inside?
No way to tell for sure if the phone needs a new screen unless you are able to test the motherboard in another N5.

It's been dropped a couple times but not like any major drops or anything. Im pretty sure I checked all the connections inside and they were good. Im starting to figure out that the phone has to be off for a little bit then I have to charge it and turn it on and it works again

Sounds like it could be a damaged lcd or lcd connection. If it can work after being charged while powered off, could be battery or USB flex cable issue.

Ya I figured out I have to reboot it a bunch of times then it will work

I think it might be the battery because this is my dad's old phone so it's been in use for a solid 3 years.. I wish I knew for sure though

So I have discovered that if my screen is on for a while the task bar at the bottom starts to shift up and down

Have you found out more about this? I think I have the same problem. My phone never turns black while I use it. But when the screen is off/sleeping, it sometimes won't turn on again. So a force reboot fixes it. Sometimes this happens a lot, some times it works fine a whole day.

Maybe, I don't think so. My phone was useless, black screen on every screen unlock. But namelessrom took that away, so that tip about nameless was for those who have the same black screen I had earlier. But now I have the same black screens as you do. Anyway, if you want to try it out, nameless-rom.org

Is a firmware problem?

I'm trying to buy a new flex cable to see if it will help I'll update when I find out

You're replacing the USB charging flex cable? If you are, be careful with cheap third-party replacements as I have read reports of people having issues with charging, signal, or speaker functionality after installing the cable.

Ya so i sent it to LG finally and the diagnostic said that it was a flex cable issue which I was sure that it was anyway but I have a confirmation now

I've had a similar problem when my display suddenly started failing. First, there was colourful bands over the working display, then colourful static only and then black with backlight only. Bought a new phone, left it for a year and today after digging in the phone for a while I found a fix. The connection between the motherboard (the top bit) and the daughter board (the bit below battery with USB and connection to display) was somewhat loose and when pressed on, the display worked beautifully. I stuffed the insides with some tape to maintain pressure on the connection and phone works great.
Might not work for your problem, but it's worth a try if you're out of warranty and have tools to disassemble the phone.
