Marantz SR6004/SR5004 Owners' Thread - Page 6

Units have a lot of room to breathe. Over-heating should cause it to cut off and power back on once it cools. Whatever is causing failure of the SR6004s is permanent - they will not exit protect mode after the "thud of death."

Out of curiosity, how do you have your cabls/sat box connected?

Here is the first unit that died. There is roughly 6" above it and an 1.5" on either side with 4-5" in the back.

The other unit that died ultimately expired in my bedroom armoire.

I emailed this to marantz via their website - I will post their response

Re MARANTZ SR6004
I have purchased two Marantz SR6004s from my local dealer. One died after roughly 8 days of use. It was replaced by another. The replacement and my second unit also have died after roughly two weeks of use. They were in separate rooms and took the place of a recent Onkyo that never had issues. The failure was complete, sudden and without any logical explanation. Two were simply on for tv and one with just the tuner. All three occurrences involved a loud thud or pop from the speakers and the receiver going into protect mode. They will not leave protect mode even when unplugged overnight. Are you aware of any model-specific design or hardware problems effecting these models? I put my old Onkyo in its place and it functions without issue. I have ruled out any electrical surge or speaker connection issues. Once again, the SR6004s worked beautifully up until their failure. Please advise - I am unsure if I want to try Marantz for the fourth and fifth time after these complete failures of all three SR6004s I have tried. Hats off to my dealer - has been incredibly helpful and has been the only bright spot in this experience.

Bob, I for some reason have also felt like there might be a low tolerance to a surge emanating from the cable box. In one case the receiver was hooked up via optical and the other via hdmi when the SR6004 died. I have a $75 phillips surge protector in both room, but not a line conditioner (have never needed one). I wonder if these Marantz's are hyper sensitive to the everyday fluctuations that might occur from ungrounded coaxial cable feeds.

The strange thing is why these have died randomly, but work perfectly without any warning of the coming failure. The first was warm; the second very cool.

I want to make the SR6004 work in my house and am going to let Marantz offer suggestions. I can't be this unlucky - someone else has got to have similar issues. I have scientific atlanta 4250 hd boxes in both rooms and they might be the culprit - either way - seems that the 6004s are way too sensitive considering numerous other receivers - from onkyo and denon - were in the same setups without issue for over two years.

I will be surprised to think that the problem might emanate from the cable, but it is the only thing i can think of at the moment as my old 906 is back and running without an issue.

How many folks on this thread own a 6004 versus a 5004? Just curious how many of these are out there and we'd hear about such issues.

and i think the 5004 is definitely the to go save the fact it only has "is it 2007?" 3 HDMI inputs. the bluetooth deal seems pretty gimmicky - will not work with my computer and doubt the wattage difference is really true at the end of the day (from reading power reviews of the 5003 and reading power consumption specs).

so...I might have my fourth unit tonight...my dealer has been terrific. if anyone is in texas and looking for a dealer that has the patience and committment to replace three units within three weeks, pm me. he also sold it for 30% under msrp

Marantz said they had not heard any similar reports but the model is very new. The CSR kept returning to the hypothesis that the cause is heat related, possibly an internal thermostat gone awry. He did mention that the 6004 has an all new power supply beefed up to give it more power than the 6003.

I have my fourth Sr6004 in my study and it worked perfectly last night. Having setup four of these, there is some truth to Marantz's commentary of a break-in period. I was a bit shocked when I first powered up compared to my previous that was broken in for about two and a half weeks. They take a couple of days to break in. Do not think it's merely placebo effect after testing four.

I have not tried a 5004, but from my discussions with Marantz, they differ on a lot of parts, namely a much beefier power supply. They obviously have a large hdmi board as well.

Anyone actually own a 6004 besides me???

out of curiosity, do you know where it came from? AVID in Dallas by any chance?

Thanks - any other US or CA owners? Trying to see if there was a bad batch over here.

A buddy of mine who has a repair shop thinks that since I hear a thud when it died, the problem lies in the output section of the receiver and not the power supply.

Marantz noted my case, but their suspicions targeted heat issues...he claimed that Marantzs fully lock up in protect when they get too hot. Kind of annoying - I would have thought they just turn off.

I think your problem has more to do with hdmi trying to land on the lowest common denominator than a design flaw with the denon. That said, most receivers allow you to turn off the audio output from hdmi to the tv. I would have tried that on the denon to see if it corrected the problem.

Otherwise, HDMI handshakes recognizing your dvi only tv might force you to run a separate audio connection (ie optical from cable box and analogue from bd player). I am afraid the problem is really the older spec'd tv and not the denon.
