Open the back cover and check the fuse on YSUS Board. If the fuse was gone, replace the YSUS board or ZSUS board.

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

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.

Tv has sound but no picture


Usually a shorted Y-driver/buffer board( skinny boards on left edge) one or both, don't run this model TV with these boards unplugged. Also less likely but possible is bad Y-sustain board (bigger board on left side)

My LG 50PG20 Television has audio , but no picture


If its just your video than I think its your back light inverter. However it could be the main board in your TV. I would call a repair man to come out and take a look.

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.

I have an LG 50PG20 50 in. HDTV Plasma and went to hook up my Mp3 player to play music with the USB cord and my TV always says the USB is not found??


Your LG 50PG20 TV don't provide mp3 players or HDD's, this usb i guess is only for firmware aka for services. Or just you must change your mp3 system to FAT32 or FAT .!
