No video ,only audio after samsung TV flashed for a second.

I bough a Samsung HD Plasma TV Model no: PS42Q7HDX on 2007.Suddenly the screen is flashed and there is no video only i can hear the audio. I called up the service centre.They came and picked and told me that the TV is faulty due to COCKROACHES. But my home is pest controlled for 3 times.so they can't fix it. Could some one help to solve the problem.

I have a Samsung 50" plasma, that has been blacking out over the last 6 months. A 9/2005 set. Now its practically unwatchable as it happens 3 times in an hour. Its not heat related - I have a high volume 9" fan activated on TV power on. Turning the set offf/on usually makes it come back for a now short while. Considering to go put it in the back of my pickup and park it in front of Best Buy and discourage Samsung purchases. This is the 2nd Samsung TV I've purchased (the other a 32" tube) I gave to my folks a couple years ago and its gone bad as well. Samsung product may look good, but their video engineers are not.

SOURCE: Samsung DLP HL-P5063W. . .no lamp!

I have the exact same problem, TV stared doing it about 12 days ago, I ordered and replaced the Lamp, it still does the same thing...

""Lamp" light flashes for 20 seconds and then you hear PS clicking, repeats cycle 3 times before it shuts off and all 3 lamps flash!"

Remove the rear cover and check the lamp cover switch. Earlier versions used a black plastic switch holder that may break due to improper assembly. The part number for the holder is BP61-01240A. Newer versions use a metal tab attached to the engine. In this case, improper assembly may cause the lamp cover switch to be extended past its range, either breaking the switch or causing it to have an open contact. Replace the switch with BP91-01231A.

Note that in these models, when reinstalling the rear cover, it is best to remove the lamp cover first, install the rear cover, then install the lamp cover. This will make sure that the lamp switch is properly engaged.

Sounds like it could be a bad capacitor on the power supply, or possibly on the video out circuit. Bad capacitors are a common problem in Plasma and LCD monitors and T.V.'s.

Could be the power supply inside the TV is bad. Check with your local authorized Samsung repair center. DON'T try to fix it yourself.
