Question about Harman Kardon DPR 2005 Receiver
My amp will power on and light up, but then switches itself off after only a few seconds. Can anyone help? thanks
SOURCE: I have a Harman/Kardon reciever
Hi, I am beginning to come across this issue with Harmon/Kardon receivers repeatedly. I recently wrote a short article suggesting how to handle this. I'm not sure whether or not my suggestions will be effective. They would normally be generally correct for all receivers. I would be most appreciative if could you let me know what happens. Best Regards, Mark
Here it is with some technical explanations.
"What we are doing, in this case is looking for a shorted out speaker system, or wiring to speakers, or cables or components that are connected to the receiver that have a short circuit. This is what I would do if I were called to your house to debug your sound system.
Follow this procedure:
1 Disconnect one set of speakers at the back of the receiver and turn the power button on again. See if it stays on. If it doesn't go to step 2.
2 Remove the next speaker and keep repeating the test.
3 If it still stays off, disconnect all of the equipment connected to the unit, one piece at at time. After each time, turn the receiver back on to see if it shuts down.
Somewhere along the line, the receiver may not shut down. If that is the case
identify the the offending cable(or component that is connected to it) and replace or service it.
I hope this solves it for you. If not your receiver will unfortunately need professional servicing,

Sounds like a bad output channel is causing it to go into protect mode. Time to see a repair tech.

Followup on higlider's problem. Now it has to be turned on ten times before it stays on. Email from Harman Kardon only suggests taking it to an authorized repair shop. It is clear that it is not from speaker short or overheating, because it only happens when the rcvr is cold.

SOURCE: When I go to power
Depending on your ablilities there might be a quick fix. It sounds like the contacts in your on/off switch are either corroded or worn out due to heat. Ensure the unit is unplugged from any electrical source. By opening up the unit you will have to detach the on/off switch, and by bending the prongs carefully, open the casing up. Clean all internal part using contact cleaner. If the contacts are worn or corroded, you can try replacing or what I did was added some solder to the contacts and put the unit back together reversing my steps.

You have 7 pairs of plastic binding posts.
Unscrew the post until it comes out an eighth of an inch.
You will see two spaces in the black plastic one at the top and one at the bottom of each binding post. That space is for the wire. Strip half an inch of jacket off your speaker wire and slip the stripped part inside the hole and screw the binding post down on it and it will squeeze the wire against the contacts.
If you find that difficult since the posts are so close tommorow, a "Banana Jack" may be put on the wire then pushed into the hole in the binding post.
It is difficult to describe in writing but onece you see it you will understand.
Black posts are the negative, they are all on a common ground. Coloured posts are positive.
