Question about Kenwood KAC-7202 Car Audio Amplifier
The amp turns on for a second and i see the triangle turn red then it turns off
After reading thru many posts I have found out that this problem your having is the same exact problem I had. Amps fan is the only thing working, no light either but it used to come on for a second. Anyway it turns out I found one bad zener diode. Diode D9 1ss133.
It's over where the fuse is located, in the power section. This amp had me stumped for a month almost 2 months. Then one post led me to diode check which was my next move after I ruled out that all transistors were good. So, this is the problem. Use a digital volt meter and find the bad zener diode. They are small kinda orange in color with a yellow stripe on one end. You'll see them it's basicly the only things in that area next to the coils/chokes or loads if you wanna call them. Good luck. My amp works great now, playin as I type.

The amp is going into a protective state.You either have a bad resistor,capacitor or coil shorting internally in the amp.If you open it up you may be able to tell right off the bat of the bad component as it would be burnt or you will need a meter to troubleshoot it.
