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.
lfcfan: Hi Todd, have been reading endlessly about the topic, and I really don't think that I'll be capable to 1. do the job myself as I don't have enough of the right equipment, and it looks like only the people who have access to TI exclusive distribution networ

skydronelink: Hi Repairaj, I have the same issue, but I am not able to get the cap value, I can tell it is the same board but deffirent rev cause of the side CAP is not the same value ! any idea how I can get the right burnt cap value?

skydronelink: Hello Jerme, thank you for the those images, is there is any chance to get the C2 (Cap) value or an image for it ? Thank you in advance.

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.
