SOURCE: LG 50PG20 Plasma,, nothing shows on screen its all black

This model was known for issues with the Y-sustain, Y-drives, and the Z-sustain boards. These boards help process the picture image to the screen.

When one or more of these boards fail, the screen stays black, and you only have audio & on/off.

You could call LG and try to get your TV repaired at a discount if you can convince LG to honor this known issue.

Another issue could be the actual panel has gone bad. The plasma panel in your TV has a two warranty and LG would fix that for free. Well…it would be free as long as it’s not past two years of your date of purchase.

What zip code are you in?

This indicates a problem with the panel itself. The line will not go away. When a television is in warranty and this happens the unit is usually replaced. This is normally not reparable because it is too expensive to do so. Check with the manufacturer to see if they have a prorated purchase program to compensate you for this.

One of the Y-SUS board, the Y-Buffer board may be bad, or both. Recommended repair is to change both of them at the same time, otherwise if you could not be sure which board is bad, you change one board, you will burn it out again.

Where can I buy a new power board for my Plasma LG 50pc1dra-ua? I know that I have capacitors that are blown on the board and I want to put in a new one.

I had the same problem and opted to take the board out and replace the caps. They were all the same capacitance. Cost me $6.61 for 10 new caps (needed 9, 10 was cheaper). If you can solder, watch the capacitor videos on YouTube and give it a go.
There is a replacement for the original. You can try

Good luck
