Plasma TVs run on decent voltage. It is likely the power supply has encountered some damage. This could be a loose solder joint near a transformer, or a shorted out component. It is a lot of detective work. I would try to find a new power board online somewhere. There are people that pick up broken tvs for a living out there if you would rather sell it. Power board is their favorite type of damage and they offer extra money for them that way.

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

The screen on my lg 42pc1da tv is cracked is it cost efective to repair or replace the tv


That's a tough one to answer with constantly changing prices, and different prices in different areas, but in most cases, a plasma screen is more expensive to replace than the entire unit (especially if you move to LCD or another technology).
You'll have to call around your area and see what places quote you for a new TV and what shops will charge to get you a new screen.

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:

Hello

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
