I HAVE AKAI PT50DL24XISMS IT COMES ON FOR 30SEC TO 1MIN THE PICTUREGOES OUT THE SOUND STAY ON THEN GOES OFF

Let us know what exact model this is. It is possible that this is caused by a bad power board which then causes your backlight to turn off, but can also be a T-con or main board issue. Let us know if only your picture turns off or if you lose sound as well and if the picture comes back on. You do want to try to reset your TV. Unplug it and push and hold the power button for about 30sec-1min then plug it in while holding the power button depressed. If that does not help, remove the back of your set and post some good images of your boards with your question. That way we can see what you see and could try to assist you further.

When was the lamp last replaced in this unit?

no you wont hear a sound if your power supply is bad.try to go where you bought you tv because it may factory defect.hope it helps you

You could be right it sound like the power suply, has it got a AC adaptor power suply,bit like a laptop charger? goes from mains to a black box then from box to the TV?
does it stay on at all?

You can put a small fan inside where you suspect the over heating occurs. Place it so that it blows air to the aluminum heat sink. This is probable the easiest way to fix it. I fixed TVs for customer this way before and they never took it back to me. Be carefull where you get the power from your fan.

check you condenser fan motor make sure it turns on, if ok you must clean the fins on the outside unit,with a water hose , make sure you turn power off first before taking a water hose to unit

That foam block is an anti vibration dampening device. My guess is is goes up against the underneith od that compressor. The real problem is with the short cycling compressor. I would return that piece of junk.
