Strange screen blinking?! help please!

Got yesterday my Acer A500 and its really great.
But a few minutes ago I got a strange problem ( not rooted or flashed yet, just the normal 3.0.1 stock rom )
battery was down to 10% and then the screen started blinking ( turned off and on again and again). while this I also couldn´t use the screen everywhere.only several areas worked.
do you think that I should send it back for warranty or just wait?
help would be appreciated!thanks in advance!
didn´t remove this acer sticker and just recognized that the screen has problems that touch input doesn´t work, so removed it and it works again.tested again with the sticker -> screen blocked -> removed -> works again...lol maybe the solution.because this was like touching the screen, although the first day the sticker didn´t effect the display usage

I would say yes. To sending it back if you got it online.I drooped my very slightly same kinda thing I took it apart and was the. Monitor connector loose.my GPS radio antana was lose as well. Go figure. I put drop of silicone on the connectors to prevent them from coming loose again

now battery stats hang. it remains on a certain percentage and only after a reboot it shows the current stats...don´t know what to do...

Did apply a screen protector that was wet application or get the unit wet in any way? If so, you may have moisture contamination in your unit.

First of all, the above statement makes me shudder.
Anyway, it really does sound the unit has moisture contamination. Not much, but enough to throw a few circuits off.

All this is waaay too funny ! I really didn't know. Damn it now I'm nearly to old to do anything about it. Back to topic, agree it may be moisture. Give it a day or two & a good charge & see what happens. If not try a reset then exchange if not working. Good luck.

the blinking issue only was once and also the battery now seems to be fine.really nice tablet though

The screen on/off problem is resolved with the OTA firmware update and the Honeycomb 3.1 update. No sense returning the Iconia because the new one will still have to wait for the updates to be pushed to the device. The problem will be resolved automatically as soon as the updates are pushed to your device.

Does the computer recognize it?

If you're talking about no power at all, it doesn't sound like a software issue. It sounds like an electrical issue.
If the screen backlight comes on when you hit the power button, then it could be software or electronic (borked chip, broken circuit board, etc)
Plugging it in, even if it's a dead phone, should still charge the battery if the electrical circuits are good. The LED will come on at orange or green and that should tell you if there is physically electricity running through the circuits.
If you get nothing, something in the phone died. I'm starting to realize the MT4G has a pretty poor build quality.
If the battery is charging and the backlight comes out, maybe a quick vibrate to indicate charging, then you could have some kind of an electrical short in the circuitry somewhere.
Or you just have a bad power button. That's a possibly. But that's odd that it turned itself off. That's what makes me think the power button itself isn't what's wrong.
In all cases it sounds dead. If you can't get to the recovery screen there's not much you can do.

no led lights it just died lol... it wont do a thing. im starting to think that it has some kind of short between the battery and the circuit that distributes power through out the phone.. thats my best guess.thanks

You can also check to make sure the battery isn't the problem by removing it and plugging the phone in. Again, the best you'll get is a brief flash of the backlight. But if you don't get that, you can be sure the battery itself isn't the problem.
Or just put a new battery in and see if that works.
This is highly unlikely to be the cause. But it's all about narrowing the possibilities. I've been fiddling with electronics for 20 years now. One thing I'm sure of is that you should never discount the really unlikely source of a problem. It won't usually be the answer, but every once in a while something you'd just never suspect ends up being the culprit.

I had the exact same issue, earlier this year. Your emmc chip gave you the bird. Go into Tmobile store, tell then your phone won't turn on, you tried the normal tricks, but nothing works. Act a little dumb with them,I did that an got a new one under warranty for $5, came in the mail the days later. DO NOT MENTION ANYTHING BOUT YOUR PHONE BEING ROOTED. If you do, your gonna have to pay full price for a new one or though the issuance company a $130(or whatever your deductible is).
Trust me on this, it works. I'm still using the phone they sent to me back in June.
If I helped, give thanks(via the button )
From my fist to your face, enjoy!

Well, my Nexus 4 lasted a month.

Went out yesterday afternoon with some friends, had about 80% charge on the battery. Probably an hour into my night, I went to check my phone (i always keep it in my front pocket), and to my confusion, it wouldn't power on. Okay...maybe somehow an app left running killed the battery (although I think they designed the phones not to do this). Fast forward about 4 hours, when we get back home. I plug the phone into the wall charger and instantly see an unfamiliar blinking red led light just above the charge port. The phone wouldn't power up, decided to check back later. 30 Minutes later, still nothing. 8 Hours later on charge, still nothing.
I've tried hard resetting, I've tried holding the power button for 30 seconds, I've tried holding all three simultaneously. I guess it's just a dead phone.
I didn't root the phone, I didn't custom-rom the phone, no 3rd-party kernel...nothing...she was completely stock.
I called google, their support agent wasn't familiar with the phone. Said he'd get an RMA started, would email me the details he needed from me...never got back to me. I'm pretty pissed.
Waiting 5 weeks for a phone that dies in a month....not a happy camper.
UPDATE! FIXED IT
Following the guide here:
http://www.ifixit.com/Teardown/Nexus+4+Teardown/11781/1
I took it apart, disconnected the battery lead, and reconnected the lead...poof it boots!!

UPDATE #2
The phone "died" again. Took it apart again, pulled the battery, again. Factory Reset, the phones been on a charger since then and it is still on, we'll see how it lasts the day.
I'm not sure if there is any proof of this, but I read somewhere that benchmarking apps can cause this(?) I had Quadrant installed on my device shortly before this happened. Anyway, I'll let you guys know if I have any more problems.
UPDATE #3
I've lost it again. I don't know what to do at this point...

Before I proceed,
1) Are you comfortable working on electronics
if yes, continue to 2. if not, stop here.
2) Do you have the appropriate tools?

Yes and Yes, but I don't want to void my warranty on such an unknown problem. I'd rather see it replaced and they can research the problem on my phone and try to prevent it in the future so others don't have to go through this. Thanks

Don't you just hate the fact that some random employee at Google will easily have access to all of your personal data left on the phone?
Oh well, at least you get taken care of.

I'm not aware of any warranty/void stickers on this phone.

have you seen this?

If
If the phone battery has been discharged too far then it becomes dangerous to try and recharge it as it can explode, this is why these sorts of safety mechanisms kick in sometimes.
Your only option is to send it back, if the battery safety device has been activated, it will be permanent and can only be fixed by a new battery

Phil

Are you sure? Can anybody else verify this? What were you going to suggest doing? I'm having lots of complications with the RMA process because i'm currently visiting in England until the end of the month and then I'll go back to Germany where I'll be living for the next ~7 months. I got this phone last month when I was visiting home in the US. It's a total disaster and if disconnecting and reconnecting my battery is all I need to do (and I won't void the warranty), I'd prefer to give that a go.

oh and another thing...when I connect the phone to my laptop, the USB connect/disconnect sound plays every 5-6 seconds. So it seems like the phone is turning on, and then off again...over and over again.

I figured that all this red light stuff could be solved by a simple battery pull, but LG was too STUPID to realize that people need an accessible battery and now to even try it, you have to open the phone and unscrew the battery connector.

There you go. You've confirmed the fix.

HI EVERYBODY.
I'm back. The phone has done it again. I've not got the patience to peel the back off, but it's gone into the blinking red light on charge/not booting up at all mode.
GOOGLE/LG, IF YOU'RE READING THIS, Send us all a new battery as well as the tools to replace it, and update the software, too. I'd also like $50 for the trouble, and please, fire every single "support technician" that thinks the sim card is behind the battery on a nexus (I've had that 2 times now from support)
The phone is great when it works, but it's "infrastructure" is absolutely god awful.
Will report back. Recommendations are welcome!

Nope, I haven't done that. I just took it apart and reconnected the battery for the 3rd time. I really don't know what the f**k to do at this point. Does anybody have any idea what could be causing this? Google will not allow me to RMA the phone because I bought it in the US and I live in Germany (they won't ship it to Germany for some **** reason).
ahhhhhh!!

It's lasted through the night off the charger on Franco's Kernel and CM 10.1
not sure what that tells us, but I'm happy!

I'm 90% sure all of these weird battery problems + red light are because of stock charger!
Search around and see..

But instead of telling us to search, could you provide us with sources? Because this is interesting.
Somebody should compare the LG charger with another good quality charger, a Samsung or Nokia for example, using a scope.

Charging Port Issues

Um so about a month ago i was charging my Note and I placed it on my desks keyboard slide-out tray but the Note fell and landed directly on the charging port with the cable plugged in and it looked like it bent the port internally since the cable no longer sits flat or stiff. I am willing to open the device and fix it since my warranty is shot since I rooted it lol. What do you guys suggest?

Can you provide a picture? hard to say without knowing what exactly you mean.

well, I think your options are probably pretty limited. Personally i would probably give it a shot, but you could also send it in to evga and pay for them to fix, probably $100+ or bring it to a local place to try it?

PIVOTAL CROSSROADS... Any help is better then no help.

I am a Nexus advocate and the same will most likely be true no matter which name or branding Google chooses to use... that is as long as they don't steer away from the customizability and the virtually impossibility of a software brick.
Anywho I am a owner of a 6p. I bought it in Feb. around Valentine's day. The reason this is revenant is because @ that time is when the gold nexus came out and was on sale. The only problem being was I didn't want the gold.. I wanted the aluminum one. I was able to remedy that easily enough. I ordered a new Rear housing via ali express which came with the glass and bottom plastic piece that covered the screws. I have repaired my Nexus 5 lcd probably 5 times. So I have some experience with mobile repair. When the back finally came in (like a month). I watched a quick tutorial of a tear down. When I was applying heat I used a little too much and ruined my camera. I was able to access the camera but it was very blurry to the point of not being able to make out what ever it was. So I ordered another camera via ali express again, waited a month, then attempted another repair. This time I had no issues with the heat gun or removing the rear housing. To replace the camera was not as easy as it would have been for the Nexus 5... there are several steps involved... one of which being too take out the battery... I cannot figure out for the life of me why Huawei would feel it necessary to apply a **** ton of adhesive on a battery that has little to no wiggle room but they did. While I was attempting the removal I ripped the poly bag and could instantly smell the lithium. Soooo I ended up ordering a new battery from China again. While I was waiting for it to come in the phone fell off of my bench and cracked the screen. I had no idea if the screen would work or not until the battery arrived so I could test. Well the battery came in finally I installed it with no issues. The phone is once again in one piece but unfortunately the screen does not work, but, I am not sure that it is only the screen not working. Is there anyway that I would be able to troubleshoot or verify that it is only the screen that isn't working? This is why I named the post pivotal moment... if it is only the screen and I can somehow verify it then ill purchase a screen... but if I order the screen, replace it, only to find out that it is not the screen where the problems reside and/or it is only one of many problems then I'll probably give up and lick my wounds.. So, in a nutshell, is there anyway to run a diagnostic or anything like it... At this point ANY help or suggestions are welcome.

Well to me it sounds like you should be able to turn the phone on at least? Once it's on, give it maybe 5 solid minutes to boot just in case and try to operate it. If you see no response then try to call the phone. That would engage the screen, sound, and motor for the vibrate, if set... Go from there?

Try holding down volume down + power for a couple seconds and plug it into a PC and see if it tries to load fastboot drivers.

one of my problems is that i cannot tell if the battery is charging or not... is there anyway to bypass charging port and put a direct charge to the battery so that I at least know that the battery will charge and/or hold the charge... That will also let me know if my charging port is working or not.

How long have you had the phone plugged in to a charger?

After installation probably 4-6 hours.. That's the beauty about Liith-poly... The rules of NiCd and NiMh are obsolete and do not apply... unless you are using one of course. Anyways a couple hours here an there..

My apologies about the tardiness of my response.. I put it on the charger yesterday for a good 8 hours..
no matter how long i push the power button I receive no response from the phone..
I've tried this while having the phone connected via USB to the pc..
I've used a multimeter and it reads 3.7v which is right on par but I have no way to test under a load to confirm that it remains at that level.
I'm curious to know if there is a way to test without battery...

No worries, we all have lives.
And well, the only thing you could really do would be to remove the battery and then jump the terminals from an external supply.
It'd be the same as using a laptop with the battery removed and having it plugged into the wall still.
