Marantz sr7200 sound cuts out after 5minutes,not completely, just sporadically. No excessive heat or anything- Is there a fix for this? I have a Marantz SR 5000 with a similar problem. The sounds cuts off for a few seconds or a few minutes.I can not seem to find a pattern or a fix!

Most likley, if I'm right, you have heard some staitcy, crackly noises, accompanied with this failure. If so, the problem is without a doubt on the D.S.P. board, witch is the one with the optical jacks on it, The culprits would then be I.C. 719 & I.C. 720. This is a common problem with this model, and the sr6200 & 5200 as well. A low tech method to confirm this is to touch IC 720 (the smaller one) while it's on. If you can keep your fingertip on it for at least ten seconds, it's ok, and the problem is elsewhere. If not, (IT WILL BE VERY HOT) the the board must be removed (27 screws from left to right) and replace BOTH IC719 & IC720.

    I have the same problem whith a sr6200 and I have tried this test you explain. In my case the IC720 has a normal temperature, but the IC719 really burns!. You can't keep your finger on it for more than a second, so I guess I have to replace both also, don't I?

    Thank you very much.

After listening for awhile the volume will automatically cut to a lower level, then iuse the remote to turn up to correct. does this sound like dirty contacts?


I would thought no. Generally you would only get that effect if you had moved the control yourself. Many amps now use a IC for volume control. That could be playing up. It could be a dry joint, if the sound effects some movement in the unit, but it seems unlikely.

My Marantz SR-5000 will not power up. All connections seem to be fine. Does this receiver have a fuse?


Doug
Did you ever get this problem resolved? I have a chance to buy one of these from a guy who indicates he's having the same problem, but if fixing is going to be a bit expense, I will pass.

Do have an idiots guide as to how to wire up the SR-4200 to a TV


I will interperate this as:
"So you want to play sound through your Marantz SR-4200?"

You need to clarify what sort of system setup you have, however i will put down a few ways to wire this up to your TV.

If you have a Set-top-box that gets the TV Channels, that is where the sound comes from. If you have a TV that plugs straight into the wall, you will have to get the sound from the TV. Grab a RCA Stereo cable - (White and Red heads, if you don't know what they look like, Google it).

If you are unclear about this, i have tried to make a diagram down the bottom to explain how this is to work. What you will do is Take the sound from the Set-Top-Box or TV and reroute it into your fantastic Marantz SR-4200.

1. Plug Red Plug into the the Red Slot, and White into the White on the back of your set-top-box or TV Out (if you get it around the wrong way, the speakers will be reversed.)

2. Plug the other end of the cable into the back of your Marantz SR-4200 in the TAPE input or VHS input as they are analog signal inputs. Turn on Marantz SR-4200 and turn it onto Tape or Vhs (depending on where you plugged it in).

[Set-Top-Box or TV out] >-------> into >------> [Marantz SR-4200]

If you still don't get it, then try searching You-Tube for a guide "Plug Tv into Stereo". I myself couldn't turn up anything useful

Marantz SR 5002 Won't power on


I've just been told by my AV person that is a known flaw in the SR5002 that the power supply runs hot, blows out, and sometimes takes out other components by cooking them. Thanks Marantz. How about a recall?

No output from left channel after crackling sound


Marantz SR 5200/6200 lost audio or crackling on left or right channel except in mode s-direct is now fixed !
The root cause is a defective inegrated circuit on DSP board (the one with digital inputs). To fix it change the chip CS4391 by a new one or better by the improved version CS4392. On my device a capacitor was cut close to this IC : replace one 1uF after changing the IC. For any question search me with my callsing "F5RCT"; i have a spare IC for the one who is able to change it !

Marantz SR5000 Protect mode


The Marantz SR5000 and others of it's make, design type, and year group are prone to this problem. Many such units can be reset by pressing a sequence of three buttons with sporadic results... the SR5000; however, does not provide any such option. If the "Auto protect" mode comes "on" then you know it's not a simple power supply "fuse" problem that can be fixed for a dollar by opening the case and replacing the glass fuse with one of the same rating value that is stenciled on to the power supply circuit board. (Easier than trying to read the old fuse.) If you can get the schematics and know a bit about replacing electronics parts using a low-power soldering iron, then you might want to take a shot at fixing it; otherwise, it's time for recycling. (Tip: Look for discolouration on a part on a circuit board first, this indicates overheating and a possible short. Then trace the schematic circuit for the "Auto Protect" circuit to diagnose which integrated circuits is at fault.) Typically, it costs more to fix it in a commercial shop than it's worth as someone has to pay the cost of benchtime diagnostics... the repair part is fast once the faulty parts are discovered. There are free sources on-line of the service guide for this receiver; however, downloading the plethora of rar files to assemble a complete manual is a challenge.
