    I have also had the same problem... twice! The first time the screen was 11 months old (still within the warranty). LG service replaced some components in the screen and the problem was solved... just over a year later and it happened again. All of a sudden the screen goes blank and just a few dots remain... 

    LG TV Lifespan / viewable time = 13 months....
    :( not too happy about this purchase right now!

I have a Plasma TV LG model # 42PC1DA. We have perfect sound, but no picture. Tried the contrast, tried unplugging for 30 min. What could be the problem and how much might it cost to fix it?

Did you tried diferent sources from where you get the image? For example you could try to connect a video camera, laptop, dvd or any other thing you could hook it up in your TV and check if there is still no picture.
If the screen is burned it costs the same or a bit less than a new one
Good luck

Hi Have this model for about 5 years and picture faded this morning. connected to cable and tested with a DVD input same the TV repairable or do we need to get a new one? thanks

unfortunately plasma TVs have a certain shelf life, the plasma only lasts a few thousand hours, i would'nt competely scrap the TV, put a small ad in the newspaper asking to buy a plasma, same model that has been hit by lightening or power surge with an offer, chances areyou might be able to slavage the screen.

Lg Plasma PC1DA no Picture??????

The provided description is typical for failure of a YSUS board, which is in turn quite typical for LG 42PC1DA and a bunch of other makes and models which all share the same internals.

To find out whether it's the YSUS or the ZSUS board that has gone bad look at the following article:

This is for a different make and model, but has the same core modules that 42PC1DA has.

This article also addresses the case when the TV refuses to come on, which is usually caused by a shorted IPM module on a YSUS board which, however, did not lead to burning the fuse as it normally does.
The failure is actually the same, only the symptom is different.

If the failed board is the YSUS (which is the case most of the times, but not always) then you may want to check

Finally, you may consider the following:

Should you need to have one or both boards serviced you can use the following:

Good luck!

I have a 42 LG Plasma TV with a broken screen

NO....You must pay attention to all numbers on the back of the TV. Verify these with your tech or contact your LG customer support for the correct board numbers. If the screen was broken I doubt if you can repair this for less than it cost to replace. The screen for this one runs at about $650.00. Good Luck and good advice!
