This is a common problem with any make Plasma, chances are the Y sustain module has gone bad. Sometimes it takes 3 separate modules by recommendation from mfg's to be replaced at the same time. Let me know what you have done with this issue please?

I have a 42" LG


Hi,
It can't be fix by replacing the fuse alone because the IC's and other parts are already faulty. You need to replaced the entire Y-sustain board. Try this LINK or obtain it from your local LG Service Centers.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

No Picture on LG 42PX5D


You will have either a fault with the Y-Sustain board (this I would assume from your description is the board you changed the fuses on) or the buffer board which is the long panel to the left of this board. It is probable one of the drive ICs on this board has blown & a replacement board is the best solution.

Loud pop Blank screen 42 inch Viore Plasma


Unfortunately, that board is the inverter board. And for this model the inverter board is only supplied with the the PDP panel. The panel is quite expensive, here's a link if needed:

Lg plasma flatscreen


Hi,
The boards responsible for sending signals to your plasma screen has gone bad. Technically speaking, the Y SUS, Z SUS and the Y Buffers are suspect. Sometimes, owners heard a popping sound then the display will go away leaving only sound. It's an expensive repair that can go upwards of $500. Fortunately, LG typically has two (2) years parts and labor warranty for their big screen TVs. LG has a strict repair turn-around time so call it in and you'll have your TV fixed in no time... (realistically, 5-7 days). Best Regards

LG 50PC5D 50 Plasma Won't turn on


If you check underneath the t.v there may be a button that you need to push. then you can use the remote to turn it on. took about 2 hours before I found it.

mine is located on the bottom left, right underneath the screen.
