LG 42LW TV Bootloop issue

Jan 14, 2020 11:43AM PST

Hello,

I have an old LG 42LW659S which out of a sudden is caught in some kind of bootloop.
It starts only into the LG logo screen, then dims until the screen goes black, enters stand-by and starts again. The whole cycle takes about 30 sec.

I have made a video: https://youtu.be/7FmywuVjYEQ

Looking forward to any response.

1. Unplug ALL connections, USB drives, etc. Test.
2. Unplug power, wait 20 or so minutes, apply power, test.

If that doesn't help it's in need of repair. The video and story does NOT tell you which board or such. never has.

Unplug peripherals and wait does not help

Thanks for your quick response.
Youre proposals did not resolve the issue, unfortunately.
If its in need for repair, can you guess a probable cause?

Sorry for not posting additional information about the hardware.

Its an LC420(SD)(F1) panel. I can try to identify further board numbers etc, if required.

Thanks,
Mulm

Is a mainboard but as you suspect you can't know until you swap it out.

This upsets the new tech but hey, this is how it is.

As to boards I would check out shopjimmy.com and see what boards they have for that model.

-> A repair counter here is OUT OF THE QUESTION as the min shop counter fee is 150USD plus parts. It's only a 42 inch set so how much is one at Walmart?

160USD at https://www.walmart.com/ip/Sceptre-43-Class-4K-Ultra-HD-2160P-HDR-LED-TV-U435CV-U/46867816
