There are no lamps in a Plasma display. The fault can be anything from the power supply to the drive processor. On some occasions I have seen the display itself go defective.

I would not suggest buying boards to service the set yourself. You can end up guessing at boards that are not defective, and when installing a new board it blows again, because there are other faults that were the cause of the failure in the first place.

The service rep will test the set using factory diagnistics and board substitution. When he finds the defective boards, he will install and adjust the new boards as necessary. I found that when the power supply is defective, there are usualy other faults in these sets.

If your set is out of warranty, you may find it very expensive to have it serviced.

My Philips plasma only shows half the screen. The other half is just blacked out.


This model has PiP (Picture In Picture), find the button on the remote or check manual, this mode is most likely turned on and is being shared with one of the AV channels, or try turning on a plugged in SCART device to see if this picture shows on the other half of screen.

Plasma Hyundai 42'' TV ,NO SOUND OR PICTURE


most times then not it's the capacitors on your power board that blew there for not supplying the tv with enough power if you open it up and check the capacitors it should be leaking some kind of liquid or the tops have bubbled up. its an easy fix cost>>2 dollars each

Hitachi 50" Plasma (P50X01AU), power light comes on but no screen


Hope you already resolve it, if not, here what I went through 1. Try to get a service manual for your model ($10-18) from http://www.service-docs2.com or similar place. 2. Open the back and follow instructions how to remove and test the SDR-D and SDR-U board on the far left (take one off, see if you could see half the picture). Inpsect the chips on those two boards, you might be able to spot the burned out holes (that would be the defected board, seemed to be a known issue for particular models) 3. If it is the board, go to ebay and get the pulled out board replacement ($70-90) I fixed my 50 inch plasma this way

NO PICTURE, NO SOUND On My Plasma TV.


Should have been 3300 UF 10V caps that were bad? Shouls have been replaced with 3300UF 18V. 50V is huge. If it was replaced with a 50 the polarity may be wrong or the cap it too big to be seated property. Sometimes the caps just dry out and even a normal looking one will be the culprit of no OSD. Are you getting an LED fault code blinking? That should be a red led. Do you hear the relay clicking.? When you replaced the caps did you charge them? Just plugging in the set without trying to power it on for about 20-30 mins. I may be able to help you

Sony FWD50PX2/S 50 in. Plasma Television power problem


It does sound like a power supply problem but that can be misleading because a problem somewhere else in the TV can be "holding down" the power supply. This can usually be determined by using some isolation techniques.
