Question about Televison & Video
I turn my TV to AV channel and all I get is a black screen. No picture, no sound. Standby LED is lit green. Function LED is lit red. The remote batteries are fine as I can still turn it on and off using the remote.
All of the lights are occasionally going off for brief periods too....i.e. turning itself off and then back on again.
We have been having some bad weather but surely that wouldn't cause this would it?
Is it doomed? I have had it for a while.
Hello Suzid, It looks to me like you have a possible power supply issue (poor brightness on screen, shrinking of the picture, and initially no picture) This problem may put you in danger of electrical shock, so I would suggest that you not try to repair this set yourself. I would suggest that you take the television to a television repair shop.The power supply issue could be a low power or a high power supply problem.

Alba TVs are manufactured in Albainia and the service info is next to impssible to obtain. I would try to troublehoot the deflection circuits. Possibly horizontal output or one of the regulators.

Replace the horizontal output transistor (Q502) and check the electrolytic caps in the vicinty, unsing an ESR meter. PLEASE NOTE THAT THE TV TUBE MIGHT BE CHARGE WITH ABOUT 27,000 VOLTS.

Hi to all, My 42" Panasonic plasma have the same problem. It turned itself off and now red light flashes 7 times, than after short pause 7 times again. And so on. Any ideas what is wrong??

the function light dose not represent a remote command, it simply flashes when it detects a infra red signal of any wavelenth. if the box is not turning on it sounds like a defective nor or nand flash rom. i believe that the box has a j-tag so maybe you re flash it?
so inconclusion a defective flash means no os no os means the box wont work
hope this helps
