Hello, I have a Rotel RDV-1060 dvd player with no apparent power. I've tested the power supply to discover all voltages are good except for 2 pins which need 3.5acv and they are measuring 7.2acv. I've checked the few resistors inline with these pins and they check out good. Thinking maybe the little transformer may be bad?? Schematic is available online, I'll post a snip .... Thx
D61, the 16v zener is reading approx 25dcv on both legs? My understanding is the voltage should be dropped here? Is that right?? It does pass the diode function test on my dmm.....
D 61 is a Schottky diode (according to the symbol in the schematic). Those have a very low voltage drop when forward biased. That is the reason for the small voltage difference. There may be some other faulty part.
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.
