It's not a setting or speakers.
I have now removed the mother board looking for output devices but anything meaty enough is a reg. chip.
I need a schematic or a precedent.
There is sound from the RCA but it rhythmically fades every second or two.
Something could be closing down due to heavy loading from the next components being faulty.
Cheers
Thanks for your speedy reply Nigel.
Yes, I tried the phones jack and tested it for o/c switching.
48pin SM...groan That's that then, unless I can get a schematic & start testing.
Sony didn't even have this model manual listed.
Audio ceased during normal usage.
If only I was deaf.....problem solved.
Thanks
Hi,
Screen shot?
I wrote to Sony & their forums though I have a feeling the Sony request floundered on the rocks somehow.
Are you in a position to know if Sony would be forthcoming with a schematic?
Either way & regardless, thanks for your time, effort and help & if you care to reveal if you are near Alfretom, I am nostaglic and interested.
The schematic for that board is on multiple pages 16, 24 - something like that, and each page would need to be stretched to at least three screens to be readable.

They wouldn't supply you a service manual, assuming paper ones are even available - as a Sony service agent we have to pay a yearly subscription to Assist to receive electronic encrypted ones. In common with most manufacturers they won't supply information or spares to other than their agents.

Hi,
Apologies for asking and thanks for your kind help. I do wish consumer groups would demand that all retail electronics come with a schematic at the point of sale.
Lots of other manufacturers are obliging via after market though 3rd parties are now profiteering by interposing. The internet often circumvents this. They sneakily meta tag as free but really aren't.
Was it Highway 61? I used to hitch Hike to Chesterfield College from there and get stuck in Clay Cross.
Not the same highway but as a hitch hiking musician back then, it resonated.
I will open the tv up, prod around (disturbance test) in the hope of findind a dry joint I may be able to stress the PCB into functioning and begin the search for a used board.
Hi, Thanks for your interest and kind intervention and info. Lovely. I had just got up and being confronted by the TV and it's kaputness had concluded it was a lost cause, and then you offer a lifeline. Do you have a link as I have previously searched quite extensively? Cheers
Nigel.....................Because you can see the signal path, could you find and recommend a point that I could access and add a line out from? I would be very thankfull if you could.
