In my a-97 amplifier was the chip stk350-030 broken. I replaced it and it works again. The stk350-030 you'll find in the middle. Open the hood and cut the bottom (sound weird but its true)

Hi i got a kenwood audio video stereo reciver KR- V6050 how do i fix it .when i turn it on it says protect and i dnt have a remote for it


Hi
the remote has nothing to do with this.
Its in protection mode ..
check your speakers cables first
if is all OK
then the receiver needs to be serviced the power supply section has a damaged parts or re-soldering the points again , but mostly damaged parts due to age of the device or over heated.
hope this helps
Kind regards

My vr-507 shut down to protect my speakers but will not power up now.


Sounds like the output transistors in the amp are blown. Try powering on without speakers attached - if it still shuts off your amp is blown and needs to be repaired.

Kenwood RV300 is flashing "PROTECT"


the amp has gone into protection mode .but you knew that. the reason would be a crossed speaker wire. like fuses the polar switch opens when the cables touch /cross and is made to reopen when the cross it rectifyed disconnect all speakers stand the unit alone see if it powers up then. if not let me know

best of luck

Kenwood Amp blinking Standby indicator light


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

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.

No sound from speakers


In most recivers or amps yes if there is a short in one channel all the amps go into shutdown or into the protect mode. Now if you know how an amp works then you should be able with a schematic to find out what amp is causing the over load simply by see in the schematic where the speaker output is on the curcuit and then measure for a DC B+ . Thats the amp you would disconnect to conferm that all the others were ok as an output on an amp curcuit shouldnt have more then .3 to .8 volts dc unless its unbalanced.. Seek a pro to assit you if you dont have the equipment to test the amp and for sure get a service manual or schematic diagram. Good Luck
