SOURCE: 42 inch LG Plasma TV - Lost picture

Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.

These problems are probably bad inverter board that supply the inverted voltages to the back lights. It also could be a failure of the back light itself. This problem should be taken to a service center, where they can test the inverter board and the back lights. You can got to the website of the product and check out the frequently asked questions to see if your problem or similar one have been posted and answered. Hope this helps you with your problem.

SOURCE: LG RU-42PX11 42 plasma TV has black bar

it seems to be a bad connection somewhere but I disconnected the ribbon cable and got a verticle line of snow instead of a blank line. the line is about 34 mm wide and starts 285 mm from the left edge starts on the Blue and goes to the Red pixels. so if they are 1mm wide that would be 34 bands of color.

I would sure like to figure out the solution to this one or I got a TV I need to throw away cause the o'lady is gonna bust my balls if I can't fix this!

There are several known issues that can cause that.

The top candidate is the main board, the next is the Y-Main board.

Here's a link for repairing the power supply board of LG 42PG20, which also contains a link to how to test your own board to see if it is good or not:

I have a 42" lg 42pc56 tv with perfect sound but no picture can you help?


Most common problems with no picture on plasma TVs are the 2 Y-buffers boards and the Y-SUS main board. Not being 100% sure without being there to check it out myself, I would have a TV repair confirm the diagnoses. Normally, they would charge a small fee to come to your home and check it out.
The cost of the replacement parts are not cheap. The new Y-buffer boards cost about $125 each. The new Y-SUS main cost about $200 - $350. That's why confirming the diagnoses would be a good idea because of how much money is involved for parts.

This is almost certainly the device that sends electricity to the the plasma in the panel after failing. Bring to your local repair shop and expect to pay 300-400 parts and 100-200 labour.

Lg 42" has no picture. but has sound.


Ther aren't any customer fixes for these plasma TVs. When you have no picture on a plasma TV there as many as 4 different circuit boards that could cause it. Sometimes it will require the replacement of more than one board. Call LG fro help. Depending on the age of the TV they may help with repair costs. At the very least, they can refer you to a local factory authorized service center.

My 42 lg plasma has no picture but sound


Hello nothing_can_& 20204050, My name is Dave, Are you willing or able to remove the back cover from the TV? If so do you know how to use a DMM (digital multimeter) or at least know some one that dose? My reason for all the questions is in order to figure out what PCB board is bad you need to at least test the fuses on all the main PCB boards (Y sus, Z sus and Main power supply). To do this you will need to have a DMM that can test for continuity. Most of the time the bad board in the TV will have a bad fuse on the board. Please feel free to give me a call or message me if you have any questions or if you would like some additional help! Ask for Dave @ 1-503-432-9904 / pleasefixitdave@yahoo.com
