Question about Televison & Video

1 Answer

I have a Samsung projection tv since 2004. My problem is: when the tv is on for approx 45 to 60 mins, the picture starts to flickers at the edges,contracting and correcting itsself in size. I suspect that the power supply condenser is faulty.

Yes definitely, the power supply electros will do this. Also the b + filter cap which is usually a 220mf
160volt will do this also.

The east west circuit can also produce the same problem. in this case a dry joint sounds like the culprit.

This is very possibly a power surge, can you tell me how many times the light blinks, you probably have a bad power board now if you had a power surge.

Most likely. You should remove the lamp door, pull out the lamp, and inspect it. Look into the center of the lamp, does it look dark or swollen? Does it look chalky on only one side? Did it burst? If so, you definitely need a new lamp. I hope this helps.

TV Flickers up and down and screen is shifted to the right w/ red color dominating the screen.


Hi
The most likely problem is the auto focus module.
A costly repair.
If you are going to fix it ask for a rebuilt one.
