Philips HTS6600 repair - looking for PSU Mitsumi SRA2034EK schematic

[Gixy]

This home-cinema set makes just low sound even with max volume. It is likely a PSU problem and some people have solved the problem by replacing an IC on the PSU board (STR-X6759). In order to confirm this I would like to examine the schematic but unfortunatelly it is not included in the service manual and I can't find it on the web. Anyone here ? Thanks in advance.

I'm disapointed... Nobody here with experience on that particular PSU? It is based on this STR-W6759 regulator which I don't know how to test it to confirm it's potential failure.

Without a schematic and with other people managing to fix it by replacing the STR... well, just replace it?

Yes... It's on going. I ordered it to Digikey, only distributor to have it in stock, and the result is 11€ for the IC and 18€ for shipping. I prefered not to try some ebay's seller to be sure not to get a fake. So I cross my fingers now because without a schematic it will be difficult to find the failure's cause. All electrolytic caps seem good and I've checked passive components.

Fixed!
Impressive Digikey: ordered Wednesday night, delivered in France one day and a half later.
