Question about LG 50PX1D 50 in. Plasma Television
Well There is always a part that can nswerwith this TV. LG's 42" was a recall for the same problem. Some of the Capacitors on the sustain board have overheated and died. (Board made in Korea)
These caps drop out because of problems elsewhere, possibly on the power unit or one of the other boards. It is the cheaper option to have this problem looked at and fixed professionally. Many on here who have played "board swap jockey" have had only a tempory fix and have ended up coming back to get more info and spend more money than if they had it corrected properly thye first time. The color engine has to be retuned whenever boards are exchanged or repaired. This is an involved task using a screen hatch using a circuit diagram and specialised tools.
Any chance you can claim it under warranty?
Thanks for using FIXYA.

Thanks for using FixYa. A plasma TV is a very hard working device. It is working harder than any TV that has been built before, and as a result it produces a lot of heat. 75% of technical problems in plasma TV's are caused by overheating problems. X, Y sustain, buffer boards controls picture, fires the gas, and many others functions. When either of these boards goes bad common problems include negative image, no image, vertical or horizontal stripes on picture, turns on and than turns off, and many more. You’ll need to open the back off the TV and check for any swollen/bulged/leaky capacitors on these boards and replace whichever has gone bad. All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when switched off.
Please do accept the solution if the issue is resolved or else revert for further assistance.
