Question about LG DU-42PX12XC 42 in. Plasma HDTV

1 Answer

I have sound and no picutre

I have a 42 inch plasma model # DU42PX12X that has sound and no picture at all. Can this be linked to a particular board. This problem occurred about 2 years ago and it happened again. I replaced all of the fuses but I'm not sure that will do anything. Any help would be appreciated.

Most likely you could have a fault with the Y-Sustain board or Z-Sustain board. You will need to check if you are getting the Vs & Va voltages to the baord (Vs voltage about 195v & Va voltage about 65v). If these are present then most likely the board is at fault.

Picture goes out in less than a minute but sound keeps going


Typical problem in some video/audio board. However, if this only occurs on a particular video input ie: dvd or vcr, it may just be your wire connection.

Most likely your Y Sustain panel has gone bad. I would have a qualified service center evaluate it to be sure.

Hello Tiangston9.
These plasma TVs have a common failure with the Ysus boards, more specific an IC that is underneath the big heatsink. The capacitors in the power supply became defective as well.
Check the link to find parts to fix your TV.

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.
