Question about LG 42LC2D 42 in. LCD HDTV
I HAVE A LG 50PX4D TV I WAS PLAYING MY XBOX 360 AND HEARD A LOUD CRACK AND THE DISPLAY HAS GONE OFF BUT THE SOUND IS STIL WORKING CAN YOU HELP ME PLEASE
Most likely the tv has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If its under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.
I hope I shed some light on the subject for you.
