Question about LG 50PX4DR 50 in. Plasma TV
Hi , was watching my 42 inch LG Plasma TV last night, when I heard a click noise and the picture went immediately but the sound remained fine, I could switch channels but no picture, would you have any idea what the problem is. thanks
Sounds like a capacitor blew on one of the boards. Can you detect any burnt electronic smell? If the Cap blew on the Power Supply, you can either replace the Capacitor or replace the power supply board. The boards are between $79 and $149 depending where you get it. Some of the other boards, Y or Z Sus, are between $179 and $300. If you can't do it yourself, and with many 42" models selling for $649 to $899, it might be too expensive to fix.
You can find the boards on ebay or shopjimmy, youtube has videos showing how to replace them. Hope that helps.
