A popping sound is a clear indication that one of the electrolytic capacitors has failed the big way. You were lucky it didn't fried anything else. Just open the tv find and replace the failed capacitor. Soldering is required so if you haven't done this before then its time to call someone who has.

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

I have an LG 42PC1DA and there is no screen but there is sound. Sounds like the capacitor failed from reading solution posts. I was wondering what i should expect to pay to have it fixed by someone else?

Shop rate will be $200 and up plus parts.
Yes, it can be caps failures in power supply, Z-SUSTAIN, Y-SUSTAIN boards, you also need to check the fuses on all those 3 boards, they are common failure boards.
See the pictures of the boards here:

We bought an LG 42'' plasma T.V. 42pcida-ec from dixons 2006 £1500. the other night heard a popping sound and the picture went off but the sound stayed on. LG wanted nothing to do with it and were no...

That pop was a "cap" capacitor blowing, open up the TV and look for a burn mark. And of course LG isn't going to fix or supply info for free to fix this for free, that is just good business, I would agree with them..

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!

Check the contrast settings
If you are a Technician than just check the video supply from 150 to 200 volts at all three RGB Cathodes in most of cases there would be dry soldering in others it could be due to failure of supply resistance check base biasing voltages if u can provide more information then I could pin point the fault

Good Luck
