I just fixed my plasma with same looking problem. Mine is a 42PX11. Cost me $320.00 in parts from Fishwick Electonics. Replaced three circuit boards, crossed my fingers and turned it on and am happy to report it has been working fine since for about 6 months now.

I do not know who was helping you before but the problem you are having can be caused by three boards in the tv each by themselves or in combination. Those are the control board with part#6871QCH053G, the Y- board part #6871QYH036D or the Z-board part#6871QZH041B. Without being able to do voltage and signal measurements directly for you, the Z-board is likely the culprit here. But I will tell you that even experienced tv technicians find themselves swapping one or more of the boards until they fix the problem. I am assuming here of course that you have not had problems with your tv before. The part #s I have given you are for the improved boards that LG has assembled to take care of future similar problems and come with their latest training manual for technicians. God bless and good luck.

A common problem for these is bad capacitors in the power supply, Remove the back from your TV and look at the power supply on the left hand side.
You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps
