Re: Panasonic LCD TV turns off after few seconds! HELP
The picture issue is not the main board. However if the backlight board is disconnected the TV should stay on and you should see something while shining a flashlight into the screen. You can also try to disconnect the backlight and the tcon board and see if it stays powered up.Comment

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. Sometimes, it also loops the on-off cycle several times without me pressing any buttons. If I connect an AUX cable, music...08-11-2025, 02:14 PM -
Panasonic TC-60CX800U with Power board: TNPA6060 1P
The TV starts, the LED lights blink for 2 seconds, and the TV turns off; I tested the voltages on the powerboard, and it looks ok.
Also, I could see HDM in the top corner for a second.
Is it possible that the issue is a bad LED light that forces the TV to 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.
