first thing that you can do is use the Google serch by just typing in lg 50px1d and see if you get any thing close to what you need.

SOURCE: LG Plasma has sound but no picture

Hi James,
This could be one of two problems. I can't narrow it down any further without having the set in front of me.
1. The plasma panel or the componets which supply electricity to the plasma in the panel have packed up.
2. The video processing unit in the set has gone.
As for the cost of repair, if it's the panel, buy a new TV. It'll be cheaper. If it's the component that supplies the electricity to the plasma on the panel or the video processing unit, expect to pay between 300-400 as a conservative estimate for parts. Labour would be another 100-200.

Hope this helps

Your Vs voltage is high, check if the heatsinks on the Z-sustain board are getting hot after a short time, if so replace the Z-sustain board. If not, dis-connect the Vs & Va plug connection to the Y-sustain & check if the voltages are normal (185V & 80V). If they are then your fault will be in the Y-sustain board. There is a possibility the control board (sits below the power supply) could also be a problem as it is not able to initiate the control to the sustain boards.

This condition, sound no picture, is generally a result from a failed y-sustain and/or x-sustain board. You can check the fuse for continuity or resistance using a multimeter. I am helping someone repair their LG 42pc3d, that's why I thought I'd help you out too.

I know you already replaced the board, this is for future searchers. If you heard a popping sound, then the picture went out, there is a 32 pin Sanyo module that goes bad on the board. That's probably what caused the fuse to blow. Replace the module, then replace the fuse. The module is less than half the cost of a used board. Since this was a popular model TV, there are lots of replacement boards on the used market.
