DRD-420 problems

Sounds like you might have lost a power supply. There is a glass in line fuse in the power supply section, but that is the main 110v supply fuse. If it were that one you would get nothing at all. If memory serves I think that there are surface mount fuses on that board. They don't look like convetional fuses, but they are marked with a number that starts with "f" and then a number. If you can find those and are handy with an ohm meter and have some pin point probes, you can check them just like a "regular" fuse. Hope this at least gets you going in the right direction.

Yes they look like surface mount capacitors of you know what they look like. They are very small and are a pain in the arse to replace. I usually solder new fuses piggy back on the blown one if I find one blown. I realize this info is sketchy at best. My problem is I have been out of town all week, and my receiver is at home.

I will be getting home tomorrow evening, and I will be glad to take the back off my receiver and get you some better info. I am thinking about buying this series of receiver defective in lots of 5 from a dealer, so I can repair them and do the ZKT mods to them. From talking to the dealer it sounds like some of those receivers have the same problem yours has. If I am able to get a schematic and do this I am sure I can help you out, just have to wait until I get home.

Do you wish a schematic be emailed to you? It's about a 1 meg PDF file.

lefty :D

I tried to email them to each of ya'll who expressed interest, but you've opted to not rec email. I also tried to upload to the site with no luck.

I'll now attempt to attach the file here.

That won't work.... All attachments have to go through Mili.... Have them e-mail you with thier address if they want it, or change thier profile....

Hey I'll change my profile, I didn't really look at the options when I signed up. Yea I would love to get that schematic! By the way I just got home I guess you could say I had miles to travel before I sleep. :D

Okay, no attachments allowed, so if anyone wants the above mentioned schematic, you must send me a PM here with a valid email address. It's a PDF file and is viewed via Acrobat Viewer.

Ready when you are.....:D
