Sony KV-35S66 manufactured in 1999
At power on there is the usual degauss buzz and a blank raster then appears (slightly bluish) which then fades to almost black level but never disappears.
There is no signal or noise (audio or video), either from the tuner or the AV inputs.
The remote control seems to work fine and all the on screen setup menus work fine all the time.
I connected a VCR to the RF and told it to tune. Now there is only channel 3 so it's like the tuning worked but no picture or sound is getting through.
It's not hard to find the service manual KV32S42.pdf but I have no previous experience with this set.
Google found a site saying that this can be due to problems with the vertical output but there is always a perfectly good raster just no signal. The only thing I can get it to display is its setup menus and I don't see anything wrong in there.
I also unplugged it for half an hour but still the same on power up.
So I think the customer will be told it's time for new set unless someone can tell me which board/component to go for.
I haven't moved it yet due to its size and weight.
Thanks
