Unit may have any one of several problems: defective or shorted speaker(s), -- ICs work within certain circuit paremeters; B+&B- voltages from power supply also provide voltage to secondary drivers and biasing circuits. Any shorts and/or transistor leakage may cause failure under load. The entire circuit should have been tested before use

Kenwood ka 996 integrated amp. The standby light will dont turn off. I also need to see if someone will tell how everything should be hooked up.


the standby light should be on if the unit is not 'ON' if you want the 894 to turn on when you power up the 996, then you will have to plug the ac for the 894 into the 'switched' ac outlet on the back of the 996
what specific problems do you have with this system

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on; or it may turn on but produce no audio to the speakers.

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 'nekkid'. 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.

The unnamed speaker turns off but you're SURE the amp still works? How so?

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.

Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.

Describe your kenwood manual "ka


Hi, Yes it is safe to leave this connection unhooked. The system control is what the stereo uses to remote control a cassette deck,cd,turntable etc... using the amplifier separately should be o.k. I hope this helps, good luck and thanks for choosing FixYa-Prodzilla

Most likely the output transistors are shorted. This causes the output stage to draw too much current and blows the fuses. Expect a parts cost around $20-$40. Add in the local labor rate for the total repair cost.

Kenwood basic M2 Amp Lightning strike


you can check the output transistors for short circuits with the low ohms range or diode checker . If they have failed, then it is often a good idea to replace all as much stress can be placed on an output array in this type of failure. to repair reliable, all outputs on an offending channel should be replaced.

Make sure the fuse you replaced was the same type of fuse. check markings.... T stands for sloblo... a fast blo duse may let go at turn on. The power supply may have a shorted rectifier diode in it also.

be aware however, every time a fuse of that rating blows... more damage may be occurring to the amp.
