Page 21 descriebs the microprocessor reset for USA & Canada; or other countries.

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; 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 and competent hands-on tech.

E-bay or call Kenwoods 1800 #. You can get the # from gethuman.com or google it.
Tell kenwood parts dept your model # and they should be able to hook you up.

Overheating is likely your root cause. Move the unit to make sure it is getting enough air around it and remove anything that you have sitting on top of it ESPECIALLY any device that produces heat of it's own such as your CD player. If that does not solve the problem, listen at a lower volume and/or defeat any equalization or bass enhancement circuitry.

your receiver's volume is set to loud

this worked on my kenwood vr-209.

I have a VR205 with the same problem. I can make it stay on by doing this: as soon as the display lights up turn off the power and then turn it back on quickly. Do this 3 or 4 times. Mine usually stays on after this....the relays latch and all is well I suspect one of the step-start relays as I have checked everything else out and all is in order and the receiver works fine. I would love to find a shop manual for this series of receivers. Anyone know where such an animal exists?

there's a good chance it's the receiver and not the remote. Just fixed mine this afternoon with help from this blog.

The power transformer is bad. Part # L07-2485-05 it costs about $ 85 bucks to replace it. It is the big one.
