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.

    Same issue with mine. The receiver is only 2-1/2 yrs old and switches off/on continuously and rapidly. At first, I'd shut it down and turn it back on and it would work again. But after a few weeks the problem grew worse. Now when turned on, it immediately goes into off/on action. So it sits unplugged on my table until I can figure out a solution or cost to repair.

SOURCE: when I turn my amp

It is possible that the amplifier is going into the Protect Mode as there are some errors in the board. The prime suspect can be the output section of the amplifer as it might be short therby comsuming higher current for the protection to activate.
Remvoe speakers to test, if not checck the output stages, disconnect power to confirm.

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.

I've a 2002 chevy silveraldo,4.3,it has the integrated MAF/IAT sensor. what color are the wires that i should hook my Tunesport Performance chip to?

That product won't do a thing

You don't cut into the manufactures expertise &
start changing things, unless your building a race car

You have an 11 year old vehicle
I ask- is it even conceivible to increase mileage,
horse power etc,etc if it was brand new & on a street
driven vehicle? No

Every week we get several questions like yours &
not one product has instructions,that's odd isn't it

Who are you asking these questions to & how would
any but a handful of old time car guys even know what
your referring to?

My parents have a self propelled...front drive...walk behind 22in cut mower purchased at Home Depot 3 seasons ago.....I do the maintance on the mower....sharpen blade....change the oic/plug &...

Does the mower die right away (cuts out) or does it sputter to a halt. Sputtering out would indicate a fuel problem. If it just cuts out when hot, then more likely an ignition problem. Your coil may need replacing. Take a close look at the coil wire (spark plug wire) and its routing. Make sure it's not touching part of the engine where it's heating up and has caused a "leak" to ground it out when it gets hot. If all is well then check your spark when the engine is hot and cuts out. Make sure you have a very good blue spark and not a weak one (check it cold first and then compare!). Again, indicating a possible ignition coil problem. Hope this helps and best of luck to you.

Headphones cut in and out - distorted sound

Dance_to_it -
I have had these great headphones over 15 years (I think!)
1. Are the batteries getting a full 8 hour charge?
2. Have you tried all 3 channel options?
3. Is there anything else close by that is an RF transmitter or receiver? If so, move the headphone base or other RF instrument away from each other.
4. If these are the original batteries you probably need new ones.
5. When purchasing new batteries I recommend original equipment Sennheiser BA151 batteries, not any other brand. I have tried 3 or 4 other brands, all with less than satisfying results. I have no affiliation with Sennheiser corp., just a consumer of their products (and Grado's for wired headphones)
Good luck!

RCA RT27760: Audio cuts out

I have been having the exact same problem. I tried contacting RCA customer support, which forwarded me to Audiovox customer support and their reply was that they don't handle the RT2760 model number.. they gave me another phone number to call, but it's the weekend and I got the "our offices are closed" message. Anyway, does anybody have any idea what's going on with our units?
