I have a lg 42px5d hd plasma screen has just gone black but we have complete sound? is this able to be fixed.


Thanks for contacting Fixya Support, I am glad to assist.

What is more than likely the issue is that your HD Plasma TV may have a burnt-out Inverter or bad Inverter cable, as these are two components are key to the back lighting necessary for illuminating your plasma screen.

In cases like this, it would be advisable for you to contact the manufacturer (LG) first, to see if there are any known issues they are having with your model of plasma TV, or if there have been any whole unit or part recalls for this model.

The next step I would recommend after contacting the manufacturer would be to take your Plasma TV to a local TV repair shop for a least a diagnosis to see what the cause of the screen black out may be.

This does appear to be a hardware issue, but check with the professionals on this problem, is my recommendation.

I hope this helps.

Tv sound works but no picture, was working fine the night before. Got up this morning and the screen is blank. Doesnt sound like anything is buzzing in the back, no fan and no heat. Its a 50 inch flat...


Sounds like one or more boards in your signal process has failed, but most common is the Y-Sustain. When this happens, you only get audio and no picture when the TV is powered on.

Call LG and them know you understand this is a know issue for this TV and you're ASKING for a warranty repair of this knownn issue.

800-243-0000 Before you call be sure to have the complete model and SR number. Example 42PC3D UA.AUSSLJR, 809HJB2983485

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?
