I have an LG 42"
Hello.
It looks like poor signal level is causing main board to freeze.
First I would recommend to make sure that it does not create same issue while you are using different device as a source of signal. Try DVD-player. If same thing happens with DVD player - main board have to be replaced. And it could cost some pretty penny ( part itself around $200 and more).
If "freezing" happens only while watching cable - I would recommend get cable box (if you don't use one) and connect it to the TV avoiding RF (antenna) cable. Use composit (yellow, red, white), component (green, blue, red, white, red) or HDMI cable to connect your signal source to the TV. That will assure reliable connection and signal level won't be an issue anymore.
Best regards.

I just replaced the ysus board. I have sound but
Hello.
Put your old board back - if TV will turn on and dark picture will still present - then you just have purchased defective board. If even old board won't bring picture back - probably Plasma Panel couldn't take it anymore and died.

Screen black, sound available
its either bad caps on the PSB-power supply board or the Y-SUS main board is bad or a component has failed on it. Remove the YSUS and take it to a PC repair shop the does board level test and repair. It's more cost effective to rework the exisitting board than to buy a new one. Or you can buy a refurb online. I say PC repair as they are cheaper than your local TV repair person.
Best regards

Try connecting any other device to the TV and check to confirm whether the issue is with the TV. Then, try resetting the TV to the factory settings. If the issue persists, try Power resetting the TV and check. If the issue still persists, the TV may require service.
I have an 50 inch
Hi
Thanks for using FixYa. The issue seems to be with
the Y-sus, Z-sus and the control boards should also be checked. To start with
you’ll need to open the back of the unit and check these boards for any
blown/swollen/flat capacitors. Y-sus board is located on the left looking from
the back and Z-sus is the board that is on the right hand side and controller
board is the one located next to the power supply board. Please do accept the
solution if the issue is resolved or post a comment for further assistance.
Thanks

There sonud coming from the plasma but there is no
First make sure to hit the menu button on the TV's remote and if nothing is there then friend while the set is on turn a bright flashlight on and shine at angle into the set push the TV menu button if you can see a image then your back light is not working.
You can also check the transformers they are close to were the wires plug into the panel, make sure all transformers read the same amount of resistance if not you have found a bad one. Now you will have to check to see if the power supply is sending 24v to the backlight, if not the power supply is bad. Cost backlights around 150.00 and power supplies around 100.00. Well this should help you friend.
Tv made a loud pop sound then the picture went
Hi
A common problem for these is bad capacitors in the power supply, Remove the back from your TV and look at the power supply on the left hand side.
You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps
Plasma TV colour going off
That could be the Z board, but most likely the sustain and upper/lower buffer boards. The brightness is found in the Z board. Try to find a repair shop to repair on the component level because the cost of new boards out weighs the cost of replacement.
