    Yes right as loud pop only means to be a bad component which you have already checked. Please do accept the solution if the issue is resolved or post a comment for further assistance.

    The Y sustain board only got the sound back on. Still no picture. Not even slightly lit.

    From what you have described it seems to be the issue with Y-main however, Y-buffer and the logic board should also be checked. Please do accept the solution if the issue is resolved or post a comment for further assistance.


    Thanks

I have a LG 42pc3dv with no picture just sound. I have this tv over 3 years, other people experienced the same problem, some of them mentioned the Y sustain board. Is this an easy fix.


Check the fuse on the Z-sustain module. The module all the way to the right (looking from the back) If blown (and before the set went out there was a loud pop) you need to change the IC on the Z-sustain part number STK 795-820 or 821 and the fuse. If you don't want to bother unsoldering and soldering back this part and you know the fuse is blown then replace the Z-sustain module. Do a google, ebay, or shopjimmy.com search with the model number for price and availibility.

Heard a loud cracking sound and the screen to my Toshiba plasma 50" went dark


The popping sounds are bad capacitors arcing at the high voltage input area. You need to change parts on the power supply and repair the high voltage control card located on the X-sustain..... or you can just order a new power supply board and X-sustain here: CLICK

My zenith plasma tv popped real loudlike a car backfiring and then the tv picture went black. power on green light wil turn on but it automatically cuts itself back off to the red light


There's an over current fault in the power supply or the Y-sustain convergence board. The loud pop was either a capacitor or pico-fuse breaking from excessive current overload. Sounds like 2 or 3 mosfets have shorted at the gate ends. Plasma TV's always have this problem because they generate too much heat and the components cant take the load conditions. Make your next TV an LCD...

To fix this problem have your local repair shop do it for you.....

any questions please ask.....

Loud pop


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.
