Thank you for your reply.
Yes, already have a Service manual, and I did some investigation, here is what we have so far:
From User manual, I learned that when DVD Player is plugged into the outlet and you press the Power button, you should get a red LED above the power button and when you press Eject, the device should be completely turned ON. (or via Remote, power on)
So I got very excited, that ahaaa missing standby +5V somewhere!, but no (those you see in YT videos only
Power from the wall gets on the first board that they call AC-113, that board also has the relay that we need to click.
AC-113 also has 5V reg that is working, and that 5V travels via CN106 to board FR-172, where we have some type of voltage doubler that makes that 5V to 30V I get those voltages too on the board connector. All voltages are there on FR-172 every IC and transistor w/voltage markings are OK
I am looking for something called P.CONT on pin2 of that CN106 so I can turn power relay on
I hope it's not some kinda of microprocessor (I see one down in the chain board FL-114 IC204) DVD player is built with super high-quality components, I don't think I have a leaky capacitor!!!
Two questions:
- what is triggering that standby RED LED?
- how do you know in this type of schematic what voltage is there always, and what voltage after unit is ON
Thank you.
