This TV will power up for app 10 seconds, V appears clearly on screen then TV powers off and LED blinks once. Any ideas as to what the problem may be? I have tried unplugging and holding power button for 30 seconds then powering on again and sill no change.

Hi,
I have an Anker SoundCore 2 (A3105) that I saved from the trash (well, I guess there's a reason why it was supposed to go into the trash...). The problem is that it always turns off after a few seconds (sometimes it stays on a bit longer, between 30 and 60 seconds, but it still turns off). The power light turns on and the bluetooth light starts blinking, but both abruptly turn off again. The "turn off sound" is still played after the lights turn off.

Hi all,
I have a Lenovo Legion 5 with a Ryzen 7 series CPU and RTX 3070 GPU. My issue is that it turns on and all seems fine except after a few seconds the fans spin up high and the laptop turns off after 34 seconds.
I can get into bios and can even boot and login to Windows however after 34 seconds no matter if Im at the bios screen or booted into Windows it will just turn off.
I have managed to run HWmonitor and the temperatures of the CPU and GPU are fine, I can also touch the heatsync which is warm but not hot.
I have tried a few new bios but exactly... -
Good evening, gentlemen.
I have a problem with my monitor. It turns off after a few seconds or flickers. Shining a flashlight on the screen doesn't show any image, so I guess it's not the "2 seconds to dark" I read in the forum.
To turn it back on, I have to press the power button twice. Then after a few seconds it turns off again or flickers. See video.

Hi all need some help, I've got a Dell insprion 15 3542 that turns on works for about 30 seconds or sometimes a minute or two and then turns off and wont turn on again until I remove and replug the power connector
Not heat related, everything is ok regarding to that.
All voltages are present.
Wondering if this as anything to do with one wire circuit, the charger is not original, but it was working fine
Motherboard is Cedar 13269-1 F3XMC Rev A00...
