Greeting everyone,I have LG 42SL90,there is Sound but No Video only White screen can changing channel,switching between TV/Radio other than that nothing else.
Cleaned up every possible connectors but still no go.
I noticed that the led driver board blinking red light,but seem all LED's are on.
Any suggestion what could be the problems really appreciated,thank you.

Yeah you're right,I noticed that too the heatsinks shifted.
I tapped,put light pressure but nothing happened.
I intended to reflow the mainboard but unfortunately not possible since both sides has components/SMD's soldered to it :-(
The question is,which of the boards is more likely to be faulty.
Why is the LED driver board blinking Red light??
Is that because the video processor of mainboard faulty/dry joints or because of the T-con?
Or the actual LED driver board itself faulty?
I cannot go into menu since there is NO video/picture but TV responding to remote or manual buttons.
The reason I try to fix the TV,'cause I like the borderless design and it supposed to have IPS-panel and I intend to used it as big PC-monitor in my room.
Of course I can buy new monitor or TV,but I don't like the idea of spending hundreds of $ only to have a throw away product which last till the warranty expired.
