 Hi Chris,

Service manual attached.                 Bruce

Thanks Bruce,

Customer only here for a weeks holiday so collected un-repaired. Had some doubts as to a simple job as caps  C4056(470/16) and C1538(100/25) seem remote from IC1508, might even be a power board problem as guess excess voltage/ripple maybe.

Will have a spare chip for next time though -  Chris.

Hi Chris,

Please explain. Who takes a clunky DVD recorder with him on holidays? Or perchance it was a local yokel on a driving holiday?

Hi Bruce,

It's a thought but guess some folks do - Recall chap brought a 22" CRT Sony down from Scotland on holiday, dropped it in as it didn't quite go.

You will have guessed it was those horrid Sony Tact switches, but not having met the problem before changed some rather expensive chips for about 80 Quid, and naturally it still didn't go.

Not an earner that time, but those Sony Tact buttons made the pound over the years.

Reminds me of the Sanyo VTC5000 VCR where the mains fuse popped, and some knowing chap said it was due to the secondary PS chip, so bought a dozen and used every one where the mains fuse had blown due to inadequate rating - Folks were happy with job done, as had value for money.

Tend to have a 'No costly crap on the shelf' attitude these days, as when things went LCD wept as chucked at least a hundred new replacement  RCUs and Lopts into the skip, due to not thinking ahead - Chris.

Hi Chris,

Methinks most of us are guilty of such folly. To my regret, I dumped boxes of valves, service manuals and turntable gear. Old technology. Never use any of them again. Now people are making a killing on eBay with such stuff. How was one to know that vinyl and valve audio would have a renaissance.
