Hello, lighting hit and my plasma Panasonic tc-42px24 will not turn on. completly dead. was told it maight be supply board??? thanks


Power surges wreck havoc with power supplies since they are first in line and bear the brunt of the rushing power. Try replacing the power supply board on the cheap by getting a used one on ebay to minimize the expenditure in case that is not it. Always a possibility,

It wont turn on at all


Good day to mam wendy311!!!!


If you TV is totally dead set and no red light or green light on the front...


if that so the problem could be cause of dead set power power supply board...

You have 3 choices its either repair it on your own or took it to the technician or buy a new set of power supply board..

But for me I suggest to buy a new power supply board because if you took it to the technician cost of repair is almost or higher depends on the bad parts than the new power supply board...

But before you buy a new PSU please check this simple and common parts that usually cause of dead power supply board..
  1. Transistor----Check if shorted
  2. Capacitors----Check if bulged or leak.
  3. Resistors----Check if open or change value..
  4. Fuses---------Check if busted..

I hope this solution will be helpful..

Thanks for using fixya...

I have aVizio VX42L HDTV10A. was watching a show when we heard a loud pop.Then all went dark. Would not turn back on. I took off the back cover and found the ceramic fuse was blown on the board # DPS-283AP...


This means you have a dead short, It is probably a Diode in the power supply area, but without testing board you don't know. If you know basic electronics, i would say check all diodes in power supply and look hard for something burnt and replace that also. Or just replace power board, check shopjimmy.com

Possible power supply burnt out


I've been hacking on a few of these monitors at work... we have a bunch that are dead... I have not seen this particular chip burnt (yet), but have been replacing a lot of the capacitors. To confirm the chip ID numbers you were looking at, I saw 4502C & AA5N0, and yes, they're both the same. If it comes to the caps, they should all have a flat top... if any are domed or black or sooty on the top, that is a good indication it is bad. Hope you had good luck with this. I can/t help with replacing just the chip.

No power


Bulb is definitely not cause of your problem.Normally lamp light will blink when it's defective.Dead means PSU problem .Some projectors have a overheat switch which switches off supply till manualy reset,you need to open the projector.
