Question about LG 50PX4DR 50 in. Plasma TV
Hi there, I was watching my 42 inch LG Plasma TV last night, and I heard a click sound and then lost picture, the sound is working OK, what do you think the problem is
Hi it sounds like it has had an elctric fault like a resistor failing.
The click you heard would be a internal switch that cuts off the elctric supply to the screen to stop furthe damage hapening.
It could even be something simple like a bad solder and in that case will need locating and resoldering.
How old is the telly and how often is it used.
When you switch it off leave it off for about an hour then try again if you have allready done this then it probably is a blown resistor are you sure nothing has been pressed on controll have you tried seeing if you can acess the menu screen via the remote and see if that comes up on the screen let me know ok

This is almost certainly the device that sends electricity to the the plasma in the panel after failing. Bring to your local repair shop and expect to pay 300-400 parts and 100-200 labour.

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.
