Hello, 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.
I hope that this help to rectify the fault of the projection TV....

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.

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.
  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

42 inch LG Plasma TV - Lost picture


Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.
