Strange grid since yesterday - Google Chromecast

Hi folks,
yesterday my chromecast worked as expected. Today in the morning it showed a strange black and white grid all over the screen. Has anybody seen this before?
I tried another HDMI input on my TV, another power source and completely reflashed the ROM with Flashcast. All that didn't help. Perhaps anyone has an idea. I can't return the chromecast since I'm living in Germany and I bought it on a visit to the states.
Regards
David

Looks like you are going to have to get it replaced or purchase a new one. That's normally a sign the GPU in the unit is dead/dying.

[Q] Touchscreen problem / ghost touch

Hi all, I'm wondering if anyone else has had this problem with the Note? I've seen it reported for other phones but in the Note forum, most complaints about the screen are about colour reproduction. It is extremely frustrating and I was hoping someone had any idea? I had already done a factory reset, took it to the Carphone Warehouse (the authorized Samsung service center near where I live) and they reflashed it with a Polish firmware, and it still has the problem.
Video of problem: http://www.youtube.com/watch?v=HAAWDwPVYmk
-------------Copy from subsequent post below-----------------
No problem. IIRC, *#0*# is the standard Samsung screen test code. (Personally I only tested this code on the Note and my SGS, which I used to film the video). I had also noticed that it usually happened after a bit of running (I ran an intensive flash video for 5-6 minutes). But then it started to happen just after I turned it on in the morning even when the phone was cold.
If this problem is really bothering you, I recommend you go straight to Samsung. The service I got here in the UK has been great so far. I sent it in and 2 days later, they told me they had replaced the screen and were testing it. If all goes well, I should have it back early next week. The phone number for the UK is 0330 7267864 if anyone is interested.

Having similar problem.
On mine, the issue is intermittent. Luckily I can now reproduce the problem by pressing the top side of the phone corner here and there and screen jitters/scrolls down/un responsive.
Same problem on mine...
I'm experiencing the same issue on mine as well, but only intermittently. I noticed it happens after I've been using the Note for a while and when it gets warm. I don't know if it's heat related. I still have to do more testing, but it seems like the problem immediately goes away when I plug it into the charger.
Thanks for posting the video, now I know there's a built in utility for testing the LCD

I wish I could send it back somewhere. I'm in the US, and the Note was a gift from a relative in the Philippines, who bought it from an importer. It looks like it was originally meant for Germany, so Samsung USA doesn't want to repair it, even when I offered to pay. Same response from Samsung UK.
The problem seems to be more apparent now with ICS (stock). Just like before, the problem crops up after some use when the phone and/or battery gets warm. Oddly enough, the problem immediately GOES AWAY as soon as I plug it into the charger.
temp fixes?
Anyone come up with a work around to this.
I made a portable charger at first, but now it dose it when its plugged too
maybe disable finger touches and just use the spen?

[Q] Help! Sony xperia TX updated, and now blank screen.

Hi all,
I recently bought my TX overseas, and updated to 3.197. It was fine for the first few days, until today, I turned on my phone, it came up with a blank screen.
All the functions seems to be working fine, even the touch screen, except that the screen itself is blank. I don't know what is wrong with it. I live in New Zealand, and I bought the phone in Taiwan a few weeks ago, and they don't sell TX or T in NZ, and I don't have a way to repair unless I go to somewhere that sells TX, or fly to Taiwan and get it fixed. :crying:
I called Sony in Taiwan, and did everything they suggested me to do, including repairing through PCcompanion, resetting, waiting for a few hours then turning it on again and the screen is still blank. Is there anyone that knows a way to fix this or have experienced similar problem?
I really want to be able to use my phone again. Any help would be truly appreciated!

I thought My phone died a week after I updated via Sony companion. Just needed to turn it off an on. Hold Power and Volume up until it reboots. If you have done this already I can't say I have much hope for it and return to base.
Have you not insured the phone?
In the UK you are asking for trouble if you don't insure your phone.
Sounds like you will need to pay for a recommended repair centre to fix it. Sony should be able to give you a list of contacts near you if you have to send your handset abroard then it's what you have to do.
****!! don't scared me I just bought tx today.

Did you try any of the following?
1) Install a stock .FTF using Flashtool, preferably the 7.0.A.1.307 firmware that came with the phone.
2) Downloading the Sony Ericcson Update Service program and using that to force an update to .3.197?
I am having exactly the same issue today. The phone is working but not the screen. The backlight, touch panel are all functional except the lcd panel. Could this be caused by the cable connector?
By the way, I don't think it has anything to do with firmware upgrade. Mine has been running the latest firmware for weeks until today.
Update: I opened the phone and checked all cable connectors and they are all firmly connected...Maybe the screen is busted... OP, were you using the oem battery?
Update 2: atteched some teardown pictures of xperia tx.

Blinking screen in dimmed mode

Hi !
Sometimes when I start my watch It starts to blink in dimmed mode. If I touch the screen it stops and I got standby screen but when it goes to dimmed mode it starts to blink again. It can do this for a while and then work great all day whiteout blinking. Some times it has started to blink after I take it of the charge dock. I tried to reset the watch and when I did that it worked for about a week but today it happened again. Did a new reset and removed some apps from it to see if that helps.
Anyone else with this problem ?
Are you using an original watch-face or some 3rd party solution ?
If it's behaving identical while using one of the pre-made faces, you might have a faulty unit.

I use 3 party watch face. But the strange thing is that my watch works over a week after reset. Maybe it's because I have been doing things with it to much, changing watch faces and so on. Now I have removed some watch face apps to see what happen. It has worked for a couple of days now.
Skickat via Tapatalk
Same for me
My watch R does the same and I'm using the original faces, not a 3rd party one. It started doing this random flashing after about 1 week of use. But I noticed the other night that the charger (the travel adapter that plugs into the wall) was making quite some noise... I'm suspecting it is defective, and that it could have induced the issues on the watch.
Anyhow, contacted LG and am sending the whole package for repair & check, will let you know if the issue disappears. Definitively not acceptable for me to have such a nice smartwatch but behaving like that!

Ok, just did a third reset on mine and removed every apps and I also reset android wear app and started over with a fresh start. Now I'm not using any 3 party apps. Will see if it works, if it doesn't I will also make a warranty claim.
Interesting to see what they will do with your watch, please let me know how it works out for you

Will let you know what they did to it. I do hope it's a known issue within LG and that they have a fix! Apart from that, it's an awesome smartwatch and I already miss having all the notifications and voice commands on my wrist! Everybody says Android Wear isn't very good yet, but I find it quite powerful already...

omg...seem like i am not alone...
mine is more like steph case....it will flash most of the time when i took it out from charger when 100% charge....it only flash like 3/4 of the screen. the flash is like max brightness.
initially i thought it only happen when i didnt use the adapter come in the package. but when i now use the original adapter, it still happen.
nothing can be done to stop the flashing until i power off the the watch this is depressing. i bought my watch direct from korea. now if warranty purpose, i will need to return it back to seller in korea.

Yeah... seems like a common issue if you ask me, I really hope LG knows how to fix this! In my case it was the same: only the top half of the screen was flashing. The other day, even after 2 reboots it kept doing it, quite annoying. I really thought initially that it was related to the travel charger making this frizzle noise, but seeing both your similar experiences, it is probably not related.
Can't you claim the warranty in Singapore? Before you return yours, let's wait and see if they manage to fix mine! :fingers-crossed:
This morning when I took it from the charging it started to flash, continued to do so even after a restart but then I just left it flashing and after a while it had stopped and now it have worked all day so far. Will probably appear tomorrow again. Will do a warranty claim on mine now.

Where did you bought yours? (I see your nickname and signature so I suppose you are in sweden ) ... Mine is from net-on-net. I have no probems with mine, yet, but, just in case things will start to go wrong, I need to be prepared .
As with any new release, looks like there are some problem units in the wild. I returned my first unit which had putty gray white markings on the bezel, flaky bluetooth and unreliable accelerometer and got a new unit with bright white markings, solid bluetooth and reliable accelerometer. Just like my Surface Pro 3. Took 3 units before I got one without bugs.

Gear VR: Pixelated Smudge?

Hi guys,
So I picked up a new Gear VR today and took my first step into the world of virtual reality. I got to demo it in the store and it looked great. So naturally, when I got home, I tried it immediately.
Unfortunately I have a weird issue. The living room (not really a demo, I think) is greenly pixelated (sorry, don't know how to explain it better) at first, but normal later when I get back to that screen. Also, in someplaces, when looking somewhere where there is no actual content to display, I see something like black smudges that look a bit pixelated. Again, really hard to explain. Does anyone have a similiar experience or any idea on what this might be? I already wiped my screen and the Gear itself.
I have a rooted Galaxy S6 (Xtresolite) which I am now flashing back to stock to see if that helps. I also have a glass screenprotector on it. I hope that's not the issue as I really don't want to remove it.
Any help would be highly appreciated!

I believe it has to do with your Home Internet. I get the same issue on my home WIFI, it works perfect when i use my Phone and Office Internet. It should be the case with you too that's why it worked great before you tried it at your home. Maybe, maybe not.

Thanks for your reply! That might be the case. It's very late here right now, but I'll be sure to try both my 4G connection as well as my WIFI tommorow. I do have to say that my WIFI is rock solid stable and extremely fast (205mbit on speedtest, around 25mb/s actual download at full speed). So that shouldn't be the problem .

Dead screen ?

My phone's screen just went black suddenly while i was using the phone last night. Nothing i do will wake the screen up, i tried rebooting by holding the power button, tried power+volume down also to boot into recovery .. no response. However the phone seems to be functioning as i can hear the screen lock sound. I think im stuck on the pin screen (the one to pass the boot-up-encryption). theres some vibration and feedback when i randomly press on the screen too.
The device is running Stock 6.0.1 , unrooted , stock kernel. Has this ever happened to anyone else ? could it be a software issue ?
I believe the LCD panel just went dead ..
Thanks!
Have you hooked it up to a computer and tried to see if it's recognised by ADB?

I had a nexus that had a faulty screen and randomly shut off or something half the screen will glitch out and one day it just stopped working but I could hear the lockscreen sounds. Your best bet would be to send it in for service maybe its a loose connecting or a hardware issue. When mine started acting up it was a loose connecting so if I hit the phone with my hand it would go back to normal and then it stopped working. Its a common issue if you do a google search many people have encountered this
That sounds to me like a return-under-warranty job. If you were in the UK you could quote the Sale of Goods Act, which specifies that an item must be of suitable quality and last a reasonable amount of time, but in my case when I returned my faulty N5 to Google after 18 months they were as good as gold, didn't quibble, simply replaced it with a refurbished one which appeared to me to be indistinguishable from brand new.
Since by definition your phone must be very close to its warranty period, depending on when you got it, I'd start with that. This is the link I used from the UK - maybe different if you're elsewhere, but you should find a link called "Get a call from a hardware specialist":

That makes sense. could be just a loose connector between the LCD panel and the MoBo ..
Problem is i live in Jordan and I got the phone from Dubai. Its still under warranty of the seller (Souq.com ; an online store .. kind of like Amazon of the middle east ), So i have to send my phone to Dubai to fix it. Now i could just go to a local phone repair shop and ask the guy to check the connectors, but im afraid that would void the warranty and not solve the problem ;( .

Google is supposedly a global company...

Well, if you figure out that it is just the screen, you can use this program for basic control with a lot of latency
