If it is Akai PDP4225M plasma tv then power supply board seems defective and defective Y-sustainer and Z-sustainer boards can also blow up power supply board.
Below image shows above said three boards location in tv and board replacement/ swapping is only way to rectify problem because these boards are not suppose to be repaired on component level.
Thanks.

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

Samsung plasma screen went black. Was watching tv, heard a loud pop and the screen will no longer turn on. You can hear the tv turn on but no picture. Power is still working, just a blank screen.


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.

Pop sound then no picture, just sound


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.

Unfortunately, that board is the inverter board. And for this model the inverter board is only supplied with the the PDP panel. The panel is quite expensive, here's a link if needed:

No picture, hear sound, television will shut off after a few seconds.


Lamp life is only a few thousand hours. Hopefully its only the lamp that made to noise. Don't turn on again until lamp is replaced.

Toshiba tz50v51 popping sound


Possible problems: * The TV set may be unplugged. * A fuse or circuit breaker may be blown or switched off. * The remote control unit (RCU) may be disabled. Solutions: * Make sure the TV/VCR are plugged in and the wall switch is on. * Check the fuse or circuit breaker. Test the outlet with a lamp. * Replace the RCU's batteries: if this fails exchange the unit.
