    My TV has barely visible grainy black/white picture, sound is ok.
    How to get parts for it, can I do it myself?


  • Swweeetsu Mar 05, 2009

    Yes, I have the same problem... I called a local tech.. he came to the house... took TV to his shop to check the problem and charged an initial $75 service call, which will be applied to the cost to fix. He claimed it could cost anywhere between $300 and $800. we are waiting to see what the total will be to repair....

    What a business to be in.....

I will tell you what.. Not to be annoying but I have found the parts way cheaper than you can ever imagine. The people who sells them are very professional and honest. Shipping from Ireland to the U.S. only took me 2 days! Definitely not 250.00 nor 400.00 like I've seen them before. It took me a whole year and a half to find the parts but i found them for an equivalent of 150.00 or so. I guess I would sell them for 250.00 as well, if I were trying to make money with you to be honest. Keep looking!

If your screen stays black with no sign of light even when it has been on for a half hour or so, suspect the Y sustain module as the cause. If you can see a faint but very dark picture after a half hour or so, suspect the Z sustain module. In either case the problem usually occurs after hearing a very loud pop. Looking from the back the Z board is the large board on the right connected to the ribbon cables from the plasma display. The Y board is the large board on the left with the big square heat sinks. The Y and Z boards are the most common cause for the symptom you described. The boards may cost about $250 ea. There is a white sticker on the board with the LG part number.
Good luck.

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?

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.

Unfortunately damage of this nature is not covered by the manufacturer warranty, however you may be lucky as it does not sound like the plasma panel fractured. Find your nearest LG auth service center and maybe they will find some plug or connector may have have been jarred loose. Good Luck
