KR-v7040. Why won't it turn on?

Hi fuxsiloh.

It sounds like you have eliminated all the things that could generate this symptom that are external to the amp. It is most likely that there is an internal problem that is causing the amp to go to protection mode. A power supply failure(maybe a fuse) is the only really user serviceable part inside the amp. Perhaps check for failed fuses, replacing any that may have blown with exactly the same type. BE SURE TO UNPLUG AT THE WALL FIRST:)

Is the amp still under warranty? If so, then returning it to a Kenwood service center is the shot. If you want to have a go at repairing it, I can talk you through it, but some experience with this sort of thing is very necessary. Good luck

regards

Hi,

Since it was just recently installed, would it be safe to assume that it is fairly new? If yes, perhaps your best bet would be to return to dealer/manufacturer for repairs/replacement. It is highly probable that the unit has sustained major hardware fault at least on the right channel. Even if it were just a fuse, it would still be to your advantage going that route.

Should for some reason you would venture a DIY, diagnosis and repairs of course would require fair familiarity with electronic components and circuitry, use of a VM and a soldering iron and preferable access to a service manual or at the very least a schematic diagram with voltage readings.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

The unit is in what is commonly known as "protect" mode. This means that a problem has been detected in the final output stage of the amp and the outputs are shutdown to prevent further damage to either the receiver or speakers. This should not be a difficult repair for a service shop. Expect a parts cost in the $25-$40 range. Add in the local labor rate for the total repair cost.

i had exact problem.
the bare wire speaker cables that connect via a clip connecor in back of the receiver are pushed too far in. something inside is shorting out with the speaker cables. solve this issue by either tightly twistng or soldering the wire ends ( then clip the ends about 1/4 inch long). watch out for the same issue of electrical shorts at the speaker end of the cables.
