Check to see if the 24vdc feeding the inverter board disappear whent he sceen goes black, if it is OK, then check the Backlight ON signal on the inverter board, if you do have signal and the 24vd, then you have bad Inverter board, worst case will be bad lamps.

MY philips 42 inch plasma TV model 42pf3320/10 screen goes black after a few mins sometimes. what can i do to fix it???


Try changing the input device to something you are sure, works such as a DVD player.

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.

This does not seem to be a power supply issue but rather an issue with the backlight inverter board. When the screen goes black, take a flash light and focus it on the screen from a close distance and several angles. See if you notice a very faint image. Try changing the channels to make it more noticeable. Try it and let me know

TV has gone into "protect mode" to do just that to protect against the damaging failure that has been detected, you will need a servicer to diagnose the failure. Good luck and Merry Christmas!

Bad flyback transformer. It has a short in the winding making the Horizontal output transistor heat up so when its too hot the set goes into protection.
