Loud pop Blank screen 42 inch Viore Plasma

Issue is either with the X or Y sustain board. Look for a cap that has blown or a cracked solid state device on the board. One of them is responsible for the ***** croak you heard.

Hi,
It can't be fix by replacing the fuse alone because the IC's and other parts are already faulty. You need to replaced the entire Y-sustain board. Try this LINK or obtain it from your local LG Service Centers.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Check high voltage circuit. This is near where the 120 volt cord is plugged in and a high voltage transformer, where there should be capacitor (or two). Check the voltage - should be 390 to 400 volts. If not less than 390, near to replace the capacitor.

This sounds alot like the same issue I had with my HP 42 inch plasma. Many plasmas had an issue with failures on the YSUS and ZSUS printed curcuit boards.

If you are willing and able to do some dissasemply yourself, open the TV and see if it uses these cards...if so then look at the solutions listed for the HP PL4260N TV issue.

I found the fuse blown on my YSUS board, I removed it and had it repaired by coppel TV..if you find a board that is bad, chances are someone on EBAY repairs them or swaps them out...mine cost $75 to repair and I was back in business...TV works fine again now that I had the board repaired.

Ur LCD inverter board it dead.Require changing to get the picture back.

I assume this is a plasma TV? You will have a fuse blown on either the Y or Z sutain board, there is also a possibility one of the driver IC's has blown on the buffer board, this will shut down the screen & leave the audio working normally. You can check these boards which sit on the left & right hand sides of the screen.

If there was a loud pop then it would appaer a fuse has probably blown either on power supply especially if there is no indicator light showing. If you are getting the red stand by light then possibly a different fuse on the sustain board has blown. You would need to remove the rear cover & check any of the fuses. Most likely if they have blown something more serious has occured to cause & replacing the fuse will result in it blowing straight away.

approximately $575

probably some capacitors in the horizontal circuit blown out.

Have you tried checking the fuses this is a solution i posted a little while ago!!! I was watching tv there was a popping noise and screen went blank. My husbands very practical and we took the back off the tv ,we tested the fuses with a fuse tester and one had blown we took the fuse too Maplin our nearest electrical wholesaler who found us new fuses £1.29 for a pack of 10. We replaced the blown fuse now everything works as it should. Hope this helps we saved about £275 by doing it ourselves but do make sure you feel competent enough to have a go its not that hard but do make sure you unplugg the tv from the electric before you attempt taking off the back and checking the fuses and be careful as tvs can store a electric ok
