Sony Qualia 004 beamer power failure
I'm the owner of a recently buyed good 2nd hand Sony Qualia 004 Beamer. The superb technique and build quality still fascinates me, even beside the fact that the beamer already exists since 2006. So it's an 'oldie'. I enjoyed viewing several movies and connected the beamer on the ceiling in my living room (in the Netherlands). But suddenly there's no power anymore. When I tried to start up the beamer once, nothing reacted, (because of the mains supply?) No light, no fan, no indications on the beamer screen. Seems only a 'dead system'. I measured the power on the powercord entrance. It's 230 V, so there is input. I checked and measured the fuse inside (15A), the fuse is OK. I don't know what the cause is, or how to repair. How can I measure if it's the powersupply unit of the beamer or something else? Also it's difficult to 'dismantle' part(s)of the beamer while hanging on the ceiling, but I'll give it a try. Does someone had the same problem and how was it solved? Or know how to do it? I see on ebay that I can buy powerunit-parts (USA) but how do I know if they're good working and if that's necessary? The beamer costed a lot in 2006, I payed a nice lower price in 2019, but I hope I can repair it, because I love the beamer, the design and specs. I also have a new spare-bulb , but the inside bulb seemed to be OK, because I got no warnings (1700 hrs). I have a users manual but no service/repairmanual. Does anyone have this manual perhaps? Sony isn't supporting the beamer anymore. Too old (...). Suggestions?
