Panasonic th-pz81b picture went off first then sound

[trotterwatcher]

Hi
Any comments appreciated, the tv stated was working fine then the mrs said she looked up and the sound was still on but no picture and then the sound went off. When you put power to the tv (plug in mains) the led does not do the 10 flashes I have read about, when you press the on switch the red led comes on solid, then when you turn on by remote the led flashes green a few time then comes on solid green the screen has a slight glow which can definitely be seen when I turn the living room light off and all four fans are running. Then when you turn to standby by remote the solid green led drops to solid red but the fans can still be heard running and the slight screen glow still visible when turning room light off. Turning off the tv by normal power switch on front panel does turn the tv off completely. I have had the back panel off, carefully hoovered everywhere to give a clear view of everything and nothing looks obvious (no swollen caps or anything), I also completely removed the main power board and looked both sides of it. Put everything back and there was stil no change, everything the same as described.

Thanks in advance
Neil

Comment: the TV is faulty. You need to decide whether to get it repaired or to replace it.

You should of. Unfortunately, I of only questions:-
Of you any test equipment?
Of you a circuit diagram?
What experience of you in repairing a TV previously?

lol at "of" for "have".



trotterwatcher, if you haven't managed to find a fix from searching Google and Youtube then there's a good chance that you'll be beating the pioneer trail on this one. That's not good. If you're just hoping to replace a part then I think you're going to be frustrated. It needs proper diagnosis by someone with access to a service manual. You need to take it to a repairer.

If you decide to replace boards then be careful. I've seen it where DIY board swaps result in killing new board because two boards need changing at the same time. That's an expensive lesson to learn.

If you're in Staffordshire then try Martin Dawes. They;re an approved repair agent for Panasonic.

Cheers, bit the bullet and bought a nice new one, love it and not too bothered about the other now ☺ I'll stick it on eBay for someone else to play with or use the bits

Thanks

Ask Telefaults if they want to buy it for spares.
Worth a try.
