SOURCE: 50"lg plasma tv

The popping noise you heard it's probably a capacitor blowing up in the power supply circuitry. If the TV is less than one year old, still covered under manufacturers warranty.
Let me know if you need any more assistant let me know.

SOURCE: 42 inch plasma wont turn on

I may have the fix.... Fixed two of my 50 inch plasmas that stopped turning on 1 year after I bought them. They both wouldn't turn on.... LOL Just gave me the black screen of death and a red blinking LED when I tried to turn on. I have pics and step by step instructions. Your time and under 40 bucks is what you'll need. I fixed both my sets for 80 cents. You can fix yours too.... I too got the it would be better to replace it than to have it fixed lie told to me too. I held out to the bitter end. Glad I did....

check the power inverter on the power strip. also check the caps on the board and if any of those caps have a round top it is bad and needs to be replaced. i hope this helps.

42" plasma worked fine this


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
