I am looking to replace a SR5002 Receiver that has died and will not turn on. It has a flashing red power light.
No, the Reset does nothing. 
My guess it is not worth fixing. So, Do you recommend the SR5007 or find a
NIB SR5005? Or just quit taking the hits and move to a different receiver?
When working the Marantz sounds great. This job has two marantz receivers and both have broke over 4 years.

Just had a SR5005 do the same thing, very weird.

I'd go with the SR5007 if you need all the inputs. If not then how about going with the NR1603 or if you don't need the 2nd Zone or 7 channel maybe the NR1403

It is a single Zone and connected to a Crestron system sitting in a MA RSH shelf.
So changing brands ramps up the price.
Looks like the SR5006 would work. Hopefully the blinking light of death has been corrected.
These were picked out by the client, and it seems I picked them up from Allnet back in 2008 for him.

Stay away from the 1403 unless you are positive you don't need up conversion. The 5007 is an awesome receiver, the 1603 isn't too shabby either, but for $200 you get more inputs and more power.

I've sold a good amount of marantz since 2007, the line has been good to me, and very few issues.

You'll probably still have to do some updates on a SR5007 because the codes changed to match Denon. The SR5005 is safe (only the SR6005 and 7005 we modified that year), but the SR5005 could be tough to find NIB. Even though the new Marantz AV Receivers use Denon commands they often also respond to the legacy commands, but since some inputs have been renamed you could have issues.

I am not even sure why I skipped the SR5006. Any issues with that one?

I didn't suggest it because it may be the Denon codes, I know the SR5005 is not. I only sell the 16 slim or the 6 and 7 series so I'm not sure. You could compare the commands in the Marantz spreadsheet and figure out what would work.

Thanks, Shoot me an email if anyone has a lead on a SR5006.
