Question about Marantz SR-5600 Receiver

Open Question

Amp switches off / cuts out

I've had 5 great years from this receiver. Without any changes in wiring/position etc it suddenly cuts out after 15 mins of a movie. I can turn it back on, but it cuts out again a few minutes later. I have tried unplugging it for several minutes to remove any electrostatic charge (the only tip in the manual), but so far no luck.

Power supply ok..coz the stanby red light is on?

At least the 5 volt is working. But what does the knowledge about the power supply change?
The Audio & Video receiver (Unknown brand and model) is obvious defect. Without enough electronic knowledge and without skills to repair it, it won't bring you anywhere. Did you check everything is connected as it should be? no shortage on the speaker cabling? No extra on / off switch?
Last Amplifier I got on my desk, was "complete defect". The owner / user, had it at least 5 years and did not notice the on / off switch was in the off position. I pressed the button and it worked fine. That was the first time the owner saw that switch, although the words on/off were printed under the switch.

15 year old receiver says protect how do i reset?

Hi, I start with one question..
Have it started to do this suddenly or you after have changed something on the system ?
i.e ..speaker position , or speaker cables or anything ?
The reason I asked ,your description is directly relates to short circuit on the speakers and/or it's
wires ..Receivers protection circuit activates itself if there is a short either inside (less probability )
and speakers (mostly )..
in case you have not changed any cabling recently ,I recommend you to check anyway all of the speakers wires at both sides/ends (Receiver side and Speaker side )
carefully ..
please let me know if you wish to have more help
but with more description...

DVD Receiver: Model LH-T7652SA. When I switch on the machine, the sound comes on as normal (for eg the FM radio station), then after about 4-5 seconds, the sound cuts out completely. All the other...

Generally speaking, an amp protects itself from heat, shorts and overloads.

Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.

If there is a way to cut and resplice the speaker wires at both the receiver and the speaker connections, try that. A good clean cut with no hanging copper wires is key.

One speaker buzz when cold

It works fine for a couple of minutes the starts to hum. If you turn up the volume it masks the noise but is till audible, also the video switching cuts out. after examining the components I have seen some heat discoloration in the power suply area and believe it to be power for the video board. disconecting the ribbon cable form the video board the hum goes away, and so does any video wich does'nt matter for me because my monitor1.gif does all the HD video1.gif switching. hope this may help with some noise problems.
