Sony KLV-L32M1 - Dead

(1/4) > >>

Turnip:
Hi folks,

Have one of these, dead as P. Dodo - note nothing in back threads. Plug in the mains and there is a slight clunk but no led -  Anyone had the problem - Chris - Thanks.

Saturday - Found DC feeds OK to main dual fets and also to STR-A6169 S/by chip - no S/by output however or shorts evident, so after a chip.

Tuesday - Chip fitted - no output, think up-load a shematic - might be those caps.

Hi

Check D663/D664 for Leakage

Cheers
Kevin

Turnip:
Thanks a heap Kevin,

D663 (50k) and D664 (5m)  Had checked them B4 but in circuit - never learn. Any idea what sort'a diode as they just have a red cathode band and I don't yet have the correct shematic - UF4007 perhaps  ?

Again thanks - Chris.

krl:
No Probs

Type 10ERB20-TB3 Sony p/n 650056731

Cheers

Turnip:
Hi and thanks again,

Diodes replaced and now some voltage on cathode of D663, none on D664 and no 5v s/by output.

Anyone got a shematic as thinking about those opto-isolators but don't know quite how they figure  ?

'It's a Sony' - They don't tend to say that too much in ads these days after that Smart Engine (Samsung VCR eeprom biz, and even Toshiba who had that cool android add, (Again not seen recently) used the same deck) - made us a pound though, sometimes every year 'till folks got wise.

Suspect Sammy shares are the biz.

Note that CHS do a P/S for a mere £230 + post - only our Sparky could afford one - Xmas list 2012 perhaps for all Quuq correspondents - Chris.
