SOURCE: LG Plasma 42PC1DA screen blank, but sound is ok

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.

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 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?

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:

I have an LG 42PC1DA. We were watching TV and it popped- the picture went but there is still sound. I have read through a few different posts on here and they have conflicting advice. I don't want...


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.

Has no picture but has sound whats is the problem


Do you get any menu or on screen display come up? Sounds as though one of the driver boards to the screen has gone faulty and needs repairing.

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:
http://blog.coppelltvrepair.com/2011/02/hp-pl4260n-suddenly-lost-picture-how-to.html

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
http://blog.coppelltvrepair.com/2011/03/how-to-uninstall-6871qyh053b-and.html

Finally, you may consider the following:
http://blog.coppelltvrepair.com/2011/05/should-i-replace-repair-one-or-both.html

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

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
