All Black pixels are red -- hardware issue? - Eee Pad Transformer Q&A, Help & Troubleshooting

Not entirely sure this is a good place to post it, but I was going to fly on an airplane, read a few pages of a PDF at the airport, got on the plane, then went to turn my EEE Tablet back on after takeoff, and the entire screen looked red-shifted:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
It seems all black pixels are red, though other colors are more or less okay.
I'm at a loss for what it would be. Is that a hardware problem or a software problem? Going into recovery, though, everything was also red; a friend of mine said it was probably a bad cable.
Does anyone have any advice, or has seen something similar? I'd feel really silly if I restored to stock, sent it in, and it was just some setting on an obscure settings page I accidentally changed.

Try the force power off method (10-12sec power button hold). If still getting the issue try a hard reset from the android settings. If it still does it, it's a hardware issue and you'll need to return or RMA it. Could be quite a number of things causing this strange issue. Bad cable connection, overheated gpu, glitch in the matrix, etc.
EDIT: just noticed you said 'restore it to stock'. Could also be a dodgy rom you installed. So yeah reflash a stock one.

Wow.. that's bizarre. Seems like it's a hardware thing to me .. try doing a factory reset? Do you have any accessibility related applications installed?

You mentioned it happens in recovery, what about when booting? The first Asus screen?
If so, its most likely hardware. But still try a stock flash

You didn't by any chance subject your tablet through any magnetic equipments at the airport did you?
Anyway, a search with Google with the keywords "red pixels black background" gave general results that the graphics processor has malfunctioned. You may have to get an RMA for your tablet.

Looks like a magnet got it to me.....

maby the xray machine fukkd up the sensitive ips, or maby the pressure change. this is the first ive seen of this

Did you go through the metal detectors with it before handing it over to be xrayed?
possible multiple stuck pixels?
try looking for an app to "unstuck" the pixels.
Or try youtube(Search fix stuck pixel video or something like that) and play a video in full screen. run it a few times and maybe itll get those suckers to light on and off and eventually fix it.
good luck
Speaking of airports..
Never traveled with a laptop/tablet. Do you HAVE to submit your device through the xray machine, and if so, is it a potential risk to the unit?

It's either the GPU output or the cable. It's hardware. It's broken. It's not magnetized (that's dumb-it doesn't happen to LCD) nor are those stock pixels. If it happens outside of the OS, it's not software.

Yes, you have to submit it if they ask. No, it won't harm it.

It's clearly stated on TF manual:
There are three main types of airport security devices: X-ray machines (used on items placed on conveyor belts), magnetic detectors (used on people walking through security checks), and magnetic wands
(hand-held devices used on people or individual items). You can send your Eee Pad through airport X-ray machines. But do not send your Eee Pad through airport magnetic detectors or expose it to magnetic wands.

So I guess it's the magnetic detector.

Manual schmanual. There is nothing in this device that is sensitive to the magnetic field emitted by the metal detectors at the airport.
If it had a hard drive or a CRT screen, then maybe.

Clearly not a frequent flyer.

I walked thru a metal detector and nothing bad happened to it, it's not a very powerful machine.
Edit: Maybe it has become self aware like that Droid bionic and it's trying to figure out how to kill you with no moving parts. Careful when you plug it in.

[Q] Screen Defective??

I finally opened the new eee pad today. It sat on my desk for almost 4 days. SO I open it, and turn it on. Immediately I notice small pixel lines moving from bottom to top on about 1/4 of the screen. If we were to hold the screen in the panoramic way and cut it into for slices, it would be slice 2 which has these lines going up. I really hope its not terminal as its seems to be getting better with usage. Im charging it now and will try using it some more later but something is telling me this sucker is defective and that perhaps the screen ribbon cable is nicked or not making contact properly.
Anyone else have this issue? This blow. I had 3 tablets in total and I sold the rest. I ended up keeping the faulty one. FAIL!
BTW its more prominent on darker screens. But at times its not. Its weird. On a black screen you dont see it but if its slightly lighter and I mean SLIGHTLY, you will see the lines. When the screen is fully lit , lets say the water wall paper with the cube, you see no lines. It looks like line artifacts.

absolutely not normal. I'm sorry man but I've had no such issue with mine. You might want to look at an RMA... don't want that issue cropping up several months from now.

Yeah looks like its not good. I was thinking it might be a "driver" issue and an update might help. But Asus pulled the update so thats a no go.
Taking a pic is not easy since its very small lines. I will try.
I might just go grab an iconia for the time being and compare the two. I know that, Im not going to see a replacement for some time. First batch releases ALWAYS has issues as you can see from the numerous threads up on weird issues here and there.
Its weird, it does it at random. Been clean about 20 minutes. Maybe it will sooth out

Maybe it's karma that's messing you up... but hope you get your screen fix though, such a shame
mine's been doing the same thing only in the last couple days, it seems it only does it for about 15 seconds occasionally when i first turn it on after it being in sleep mode for a while... it seems once it warms up it goes away, i haven't taken it back because it would be hard to explain when it is never consistent as to when it does it.
I bought gumbis, after about 5 min it goes away completely, even faster on white screens. It has to be the firmware, the original build 325

I've got the same issue on mine, appears to be on darker screens with deep blues... not so much on black screens or white.
Please see the attachment for where on the screen it is appearing. I may be able to capture it on video but the flicker is literally a few miliseconds and it's gone. It's only occuring on screens that are the "Android Setting" background. I've watched some video, viewed other pictures and backgrounds with varied colors and not seen the flicker.
Doesn't appear to be a software issue. I was able to use the screenshot tool and tried to capture it quite a few times and wasn't able to. I may end up having to RMA it already, just got it out of the box.

I hope its not. Mines not in the same spot, its more to the left. I am hoping its just a glitch in communication to the display. Screen capture is capturing it before its displayed I would imagine. In waiting until a FOTA. What is RMA anyway?

Return Merchandise Authorization. Basically send it back for warranty.

[Q][Survey] Is your Transformer still working?
greetz
Anyone hear anything else about this? Asus tells me up to 21 business days for the RMA and they don't offer advanced RMAs. If I can avoid having to wait an entire month to get a replacement I plan to. Newegg tells me it'll 14 business days or a refund. Disaster of a launch... the Asus "tech" I spoke with didn't know what the TF101 was, kept asking me if I uninstalled Windows 7 to install Honeycomb.
Im having this same problem, really frustrating cuz i was so excited to get it, and the screen is glitching out =/ really don't wana send it back

[Q] Vibrate Motor

Not sure if hardware questions are allowed here, but my vibrate motor (I purposely avoided using the term vibrator) is making a chirping noise now, and I'm wondering how hard it is to replace. I saw some YouTube videos on replacing the screen, but nothing specific to the vibrate motor. I build/upgrade my own PCs routinely, and also repair my laptops, cars, a/c unit, or whatever else needs fixing, so I'm not scared to work on my cellphone either.
I know what happened to cause the noise. I sprayed some electrical contact spray into the mini-USB port to clean it out, and apparently some of the spray got into the vibrate motor as well. Doh!
Probably should still be in Q/A , but anyways. If you can work on a PC, or have worked on a PC Mother Board. Then replacing the motor should be no issue. It's fairly straight forward. It will take you more time to get to it, then to actually replace it.

Probably most similar to working on a laptop with all the layers involved. PCs are easy to open and work on. On laptops, you have to remove the keyboard before doing anything else, so similar to having to remove the panel underneath the battery on a cell phone first. The biggest problem may be finding a schematic of where the vibrate motor is located. So far, everything I have seen is about changing the screen, so they don't mention the vibrate motor.

No-go on replacing the vibrate motor. It's soldered into the board, and too risky to heat it up because it's so close to other connectors. The battery and USB connectors are right next to the vibrate motor, and you don't want to melt those connectors by accident. I guess I'll have to live with the squeak. I've already turned off all Haptic feedback responses, and am just leaving vibrate on for ringing and messaging notfications.
There are places that will replace parts like that for you around here. But where you live IDK. You could ask at an electronics shop. See if they have any people they could recommend.

That was actually the advice I got from one of those shops. Very nice and knowledgable guy. He popped the back and removed the board while I watched. He said he could try it, but that it was very risky and he wouldn't advise it. I suggested spraying some WD-40 into the motor, but he said it would leave a white residue everywhere from the propellent gases of the can, and possibly corrode some of the plastic parts, which made sense. He did blow some regular compressed air into it, but that didn't help. He didn't charge me anything.
It was kinda cool when he booted my phone and saw the flash screen (a spinning blue bee at the time). It started a whole discussion about rooting.
That's definitely the route I would go. I've seen the repair shop around here do some really delicate work. They have some specifically designed equipment to get the job done. But I've seen them work on everything from a Motherboard for a CPU, to an OG EVO. A Spinning Blue Bee you say

The Spinning Blue Bee works well, but apparently the bee has a problem with the WeatherBug. :laugh:

Light bleed?

Is this something to just be expected with these tablets or should I go through the headache of returning it? Took me almost 2 weeks to receive it so I'd hate to return it if I'm being over critical...

Looks about like mine, and for me it goes away after the boot is complete and the brightness is reset to a "normal" level.

Yea mine seems to go away after the boot as well, until I watch a movie or something that has the typical black bars on the top and bottom, then it's noticeable again...
same here
i also have a spot of light bleed on the upper right hand side that's fairly annoying.
i heard this can be cured by loosening one of the screws inside that holds the lcd to the glass.
it seems that the light is caused by pressure. i would love to hear from someone who has successfully opened the tf700 without breaking it LOL
im a DIY kind of guy but $500 + GLASS =
Just got mine yesterday. I noticed something like that on boot, but haven't had the time to grab my magnifying glass. This may be a quirk of the tablet. My razr has ugly black blobs when the brightness is way low and I'm in the dark. A bit annoying, but I'm over it.
That's fairly normal. It's not intentional, but light bleed happens on pretty much every device from any brand that uses LCD or LED screens. Not all infinities have it (Europe seems to have a higher quality standard than the US) but it is quite common worldwide.
Mine has some too. I went through like 5 returns for various reasons. From the July to October. They all had various degrees of light bleed.

So my coworker who is a big apple fanboy, looks at my tablet and the first thing he says is " what's wrong with your screen?"
I didn't even bring it up to him. He noticed it on his own. Great...

Minor light bleed is normal on most LCD screens. You can put your TF700 and any Apple device side by side in bright ambient light, then enable IPS+ and maximum brightness on your TF700, and ask the Apple fanboy what's wrong with *their* screen.
(The TF700's display is one of the brightest out there - see http://www.anandtech.com/show/6036/asus-transformer-pad-infinity-tf700t-review/2)
Mine has even worse bleeding, do you guys believe I can ask a RMA after 4 months?
Would it make sense or they would send me back my tablet in the same or even worse condition?
Thanks
I wouldn't take much that any Apple "Fanboy" has to say about any Android product. They are, after all, called Fanboys for a reason. A bit of light bleed is normal and it happens even to iPad's. My wife and son both have one, one of the two has a light bleed very similar, so it's not just Androids or the Infinity.
Light bleed during booting up is perfectly normal, light bleed while you're watching movie/video is not normal. You can throw a custom bootanimation on yours so that during boot up you won't see the it.

Solder motherboard, possible? [Picture]

Attached is a picture of the motherboard.
I have made a circle on one part of it. As you can see, there is a blue thing to the right - before, there were 2 blue things next to eachother. But the left blue thing is now gone, I don't know where... But seems like it has fallen out somehow...
Is it possible to solder this together? Or do I need the blue thing there?
When trying to use the motherboard, everything works very well - EXCEPT the touch screen, I cannot do anything because the screen doesn't feel my fingers (nowhere on the screen). And no, I have no clue if this is the reason for the touch screen not to work, but that's my guess as it worked good before.
Any help would be much appreciated, I don't have much knowledge about soldering and so on, as you might already have understood from my description above...

I would highly suggest that you do not try soldering if you don't have any previous knowledge or experience. As for if the "blue thing" is needed or not I am unsure because I myself know little about what each piece does on the board. But as far as the touch screen issues goes, if the touch screen worked before the blue piece came of, it most likely has to do with it. If it didn't (or even if it did work before), try finding a second device that is the same as yours (or if its cheap and you can afford it order a new lcd/digitizer for it) and try connecting it to that motherboard and see if it works, if so problem fixed, if not, you may be able to take i to a phone repair place and have it fixed, though most times getting a new motherboard/device would be cheaper.

Thanks for the reply.. I have actually ordered two other "broken" phones, so I will receive them in a week or something... And I will do exactly what you suggested, to try another motherboard and see if it is a problem with the screen or motherboard. I am very sure it is the motherboard though, because the lcd and digitizer worked great just before I discovered that.
Would still appreciate answers regarding soldering this, if that is possible or not.

What the heck is this display issue?

Hey Guys (and gals).
My Samsung Galaxy Alpha's screen seem to have gotten an odd 'defect' which i cannot seem to determine the cause of. Normally i would just beat the **** outta google for such issue but I cannot seem to find any documentation or even a similar case regarding following issue. (am i blind???)
Description: A few months back an odd 'line' in a 'silver/metallic/greyish' color appeared on the top right of the display. The damage itself does not seem to be a scratch nor crack on the display. It more seems to be some kind of liquid material but i cannot tell for sure. As said at first it apperaed as a single straight line on the size of a fingertip but that quickly changed; as you can see on the picture it has started to fork into multiple branches and is in general growing in a faster phase than in the beginning.
At some point i realized that the phone is 'old' and a repair wouldn’t be profitable to even consider. But there is one thing that bothers the living **** outta me; i cannot figure out what caused the problem in the first place! - I am most definitely not a phone technician but i do have my share of hardware knowledge in computer devices. And this does not seem to be near any kind of damages on LCD displays i have encountered on either laptops, monitors nor phones. I have my daily routine in a IT company where i work as an sysadmin; and therefore i believe that i come across atleast some people who could be able to determine the root cause such issue. - But till now the only 'convincing' argument came from a 'hardware chimp' at my local phone store that was certain the screen was cracked and the only solution was either for him to sell me a new phone or ship it to Samsung repair.
- If the device is flipped on the side and you examine the display from the right angle it is clear that the damage doesn’t seem to be on the protective glass nor the LCD display below it. - It seems (from my pov) to be either on the inner-side of the Glass or somewhere in between the glass and the LCD (trapped air? liquid?). Besides the visuals the phone doesn’t seem to suffer any other negative effect. Touch works flawlessly and the device still seems solid.
- Therefore i ask you guys; does any of you have even the slightest idea on what could be causing such issue?
Any advice / solution models / comments / muffins will be much appreciated.
Best Regards

No offense, but the lines look awesome . I think that they might really be just air or water(liquid) that got caught in between the LCD and the digitizer(touch screen). Keep me informed.
