Service manual direct download: dox.abv.bg/download?id=44a915751c Hi. I try to repair this amp from a long time. All four mosfet 2SK1529/2SJ200 was short, R521/621 and R520/R620 was open. At this moment i remove all final transistor 2SK1529/2SJ200 i put lmp 75watts all relay close contacts but here is anather problem. On Q509/510 and Q609/610 i have 45v on BEC. I remove Q509/510 and Q609/610 from mainboar, and now i have 45V only on BE, collectors are 0v. But on service manual on emitters i must have 2.4v.... I don't have any short on all elements. Can you tell me what can i try, please.

It sounds to me like you are finding a problem with both channels still. If you need me to help you locate the problem I would have to start from scratch. Jumping in to where you are now would be like hunting for a needle. So this would mean I would need you to put all good parts back in and we can start testing from there.. Let me know what you want to do.
wolfman: Always the same sarkasm Kurt that's why I never checked in until now. I knew you wouldn't give me a cheerful answer so let you hang for a while. Removed the last part you probably are a decent guy Eye to Eye.

stridsvognen: Wolfman, its768% better thanyour Marquee for sure. As it can actually display a image.

wolfman: So how's the black level on that thing? When the screen is supposed to go pitch black do you perceive it as genuinely black? Like the opening of CARS where it goes on and off pitch black. Or Prometheus with stars against a pitch black space.. or any Sci-Fi

stridsvognen: I have had multiple Digital projectors hanging together with the Marquee, the Sony is actually the first one that i actually turn on and use, so put 100 + hours on it already.

stridsvognen: Its nice to have a new 5000$ digital to show off next to the Marquee, it makes the Marquee look like it worth all the 35000$ printed on the lable on the box.
