Hi. My receiver is completly dead. No display, no std by, no power, no relay click. Main transformer is perfect. AC relay is perfect. All power and driver transistor are normal. All fuses also normal. All chips are cold (no hot elements). Service manual: elektrotanya.com/onkyo_tx-nr545.pdf/download.html Please help:// Voltages P9011B:
Between 3pin and 4pin on Q8931 when i put DMM on diode mode, i have ''short''. When i put DMM on ohm mode, i have 30ohms. When i measure C8936 and C8937 i have ''short'' when i put DMM on diode mode, when i put on Ohm mode i have 39 ohms. On 2pin Q8931 i have 11.6v, on 3pin and 7 pin nothing.

I do not even know why you are messing with that ic. You did not even verify if it was bad. And the circuit was not verified bad yet either and you started removing stuff. You need to get the unit to turn on first. With the unit not being on that would be normal for that ic to not output any voltage.
If you decide you want to get back on track and do some trouble shooting rather then just poking around let me know.
On Q7016 put some solder or a wire across emitter and collector so you are jumping these 2 points. Then when you plug it in see if the main relay on the power supply board clicks on. Then see if the display comes on. If you hear the click but do not have a display test for AC voltage at connector P9002 on the power supply board.
jbmeyer13: Wolfy's Marquee isn't working? Did you spill a pint on it and short the MB?

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.

jaws55: Working on Pioneer VSX822K, need help finding value of ZD403, think its a 4.3 volt zener? Just won't to make sure, "no service manual"

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.

wolfman: What in the name of God possessed you to go gray.. Stoned are you?

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.
