LG LB650V 32" Screen Issue

by DarkEmblem / January 29, 2018 2:22 PM PST

Hello everyone,

I've had this monitor for a few years, but suddenly today it gave me problems out of nowhere.

My screen started flickering from a bright backlight to a dim backlight, the bright one being my standard one.

However my screen is now locked at having a dimmed backlight whilst my backlight settings are on max.
It now SOMETIMES still flickers, but not as often as in the beginning.

I've tried unplugging stuff to fix it and I meddled around a bit with the settings, but nothing seemed to work.

Does anyone know how to fix this or know what is causing this? Thanks in advance.

Sounds like a failed board or connection.

I see. Is there any way to easily determine which one of these it is?

And just to clarify, I can still see the entire screen fairly easily, but it's as if the backlight settings are on 50 instead of 100 hence the screen just isn't bright and harder to see during daylight.

Remember we've never seen any tech here tell anyone what is broken. That would be unlikely due to they can't see your set or look inside, take measurements and try to swap a part.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
