Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

SOURCE: I have a LG 50PX1D-UC plasma TV with a black vertical line

You could have a Driver Board that has a loose connection or a Ribbon Cable that has a intermittent connection to the Plasma Panel, or a defective Plasma Panel. Either one could cause the problem and I would recommend only a Qualified Service Person to check it out.
Here is LG's Customer Service Number. 1800-243-0000. They could direct you to a Local Service Facility.
I hope this helps,

SOURCE: 42" LG Plasma tv, no picture - black screen, but have sound.

Most a likely a problem with your Y-Sustain board which will then not drive the screen giving a black picture. The fuse on the board may be open circuit & need replaced but most likely you will need to have the sustain board replaced.

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?

How do i fix my lg plasma tv that has screen filled with multi collored vertical lines abd screen showint three bands of color green, light green and purple?


If you have to ask this, I assume you don't have the kills to repair a plasma TV. Then please don't start this. Opening it can be very dangerous, and without the technical skills, you even don't know where to look for. Most to the time I advice to visit ifixit, but this time they don't have the manual or video for LG. Perhaps they can show you some openings. But they never show you how to rebuild.
They can help with spare parts. So if you really want to do this yourself. On your own risk:
