[Q] sparks at top of screen then burnout

So my captivate was hooked up to my car charger. I took it off the charger (only on for 10min) and was playing around online when I noticed sparks at the top of the screen inside the screen. It was sparking around like it was moving inside the screen. I turned it off immediately via battery. I turned the phone back on and could see the screen was burned. I called ATT and as I was pushing buttons through their menu I noticed the sparks were happening again. Then a line formed from the top (sparks) to the bottom of the screen. Then it flickered and was off. The screen wont turn on at all but the sounds. ATT is sending me a new unit battery and all.
I flashed Darky's v3 today.

1. Has anyone experienced this?
2. Could it be ROM related?
Thanks!!

Souns like it was the phone. Nope that is the first I've heard of this.

Are you using the proper car charger (voltage wise)?

Yeah, I was using the car charger from AT&T.

Screen shaking while charging(especially for australian user)

did u guys ever notice that the screen will shaking when u put finger on it to scroll while i9000 recharging by samsung travel adapter?
i just notice this today
there is no problem when i using usb cable.
my travel adapter model is ETA0U10HBE (made in china).<--come with the box...
and i got the moblie from australia vodafone.
and anyone can suggest any other adapter for me to use, pls?

I have had that with the HTC Desire HD and Desire and Dell Streak before this. It's not actually shaking, it's a layer of static that your finger perceives when running across the screen, most likely because of the combination of provided grounding from the charger and the condenser effect on which capacitive screen function.

Chromecast flashing screen

So this is my problem, every time I switch from the chromecast to another HDMI port and then I go back to chromecast it takes like a minute to show after all the display flashing https://www.youtube.com/watch?v=V9GYcIZz7gQ&feature=youtube_gdata_player

I had a similar issue with my chromecast, and for me it turned out that my little HDMI cable extender thing it came with was broken. When I connected my chromecast without it, the display feedback went away.

I'm not using the extender, but if I power the chromecast off and on it will show instantly.

It could be that your TV is just having trouble with the HDCP negotiations needed to get the HDMI connection working. My DVD player always takes 10+ seconds to register with my TV over HDMI.
But a faulty cable could be part of it too - a bad HDMI cable may sabotage the HDCP negotiations, resulting in multiple failed attempts.

I've had this issue a couple of times. Turned on Chromcast and it booted ok. The TV shows the wallpaper and then turns to snow, back to the wallpaper then snow again in about the same rate as your video.
Rebooting the chromecast fixes it. While annoying it only happens once every 20+ boots for me.
I use the little HDMI extender, but I don't replug it, just reboot the device itself to get rid of it.

Snow is a symptom of failure of the HDCP decryption - the devices will need to renegotiate the handshake. Rebooting either/both devices should fix it, as will unplug/re-plugging the HDMI connection.
If your Chromecast and TV are both on wall power (ie, Chromecast doesn't get powered down) it should stay synced.

For me it started happening when I switch the image Zoom options to Automatic.

[Q] Screen On or Off when HDMI Mirroring?

I'm planning to buy a AppRadio 3 headunit for my Jeep, and use the ARLiberator app to unlock it so it mirrors my Z1 on the in-dash screen (I'll provide a link to a YouTube video below for clarification). It mirrors it using an HDMI cable into the back of the headunit (full size HDMI).
This Sony HDMI Cable is what I plan to buy, and do what was stated above, however I've seen mixed reviews on something. The Phone is cradled directly beside the headunit. Does HDMI Mirroring (the basic function, not the ARLibereator app) keep the screen on at all times? Or if I hit the power button on my phone, will it keep mirroring to the "TV"?
The ARLiberator app downscales everything, and transfers touchscreen actions and what not via Bluetooth, and then uses the HDMI Mirroring to show me the screen, as well as charge the phone.

@Wiltron That's a cool idea man.

From my experience if you turn the screen off than you will see a black screen on your receiving device.
Note that this is my experience with miracast but I'm sure that hdmi will work the same way.

Hi,
With my experience with Nexus 10 and Xoom HDMI, the screen will be on until the screen timeout reaches, if you turn off the screen, HDMI will be black too. But there are some apps that can turn the screen black, but still on, like Screen Standby . That's a good idea man.

You can "turn off" yoir display using this app: Screen Standby ♯ Root (sorry I can't link it I'm newbie). Root permissions required

remix mini wont turn on, my tv says unsupported mode

my remix mini was working fine before i turned it off. after turning it on, its black screen with unsupported mode from the tv. what could have possibly happened? i tried using different hdmi and plugging to different outlet.

Possibly a refresh rate difference. 50vs 60hz

Try to plug it on different TV or Monitor, It happened to me, I plugged it on my 4k TV, but when I switched it to my 720p TV, I got the same screen with unsupported mode. To fixed it, I had to plug it back on my 4k Tv, change the Screen Resolution to work on my 720p tv.
