Question about KLH R7000 Receiver

KLH Receiver Shorting Out

I've had my KLH receiver for probably near 8 years now, maybe a little less. Recently it's having a problem where after playing for awhile it will send out a loud pop through my speakers and turn off. It seems to be random, not after a certain amount of time because it happened 3 times in one day in a period of a couple hours but then I listened to it all day for probably 5 hours plus with no problems.

See if you can spot a pattern to the failures. I suspect that it is heat related. In the time that the unit ran all day, I suspect that the volume level was lower. Am I correct? If so, then either there are poor solder connections which are being effected by heat or there is a part that is defective. Are there any other symptoms or does the unit just shut off? If you attempt to turn it on, will it play for a while? If you can solder, look for solder connections that look grainy or have rings and resolder them.

Keep us posted on your progress,

Dan

Read this procedure to possibly fix the remote:
http://remotes.com/remotes/servlet/rs?a=Display&contents=help_deadremote&uuid=A12963989782821
They also sell replacement remotes.
Zoom in on the picture of the original remote provided on the site (or look at your own) and get the actual remote model number.

or check eBay: search for "(model of the device or the remote) remote", check the 'include description' box. Usually cheaper than the vendors.

Did you recently move any speakers around or any items near the speaker wire connections?
It sounds like you may have a speaker wire shorting which is causing the receiver to go into "auto protect" mode. Check all of the speaker wire connections on the back of the receiver and at all of the speakers to make sure the wires are not touching or close enough to possibly touch.

Probably a shorted amp. Turn it on with no speakers hooked up, if it still says check speakers,it will need service (output transistors and a couple of resistors) A few times I've seen them only need soldering of an emmittor resistor.

It is not a fuse problem, when a fuse is gone does not start at all.
It is probably the final amp circuit, there is a faulty IC in there that overheats after few seconds and the unit goes off by itself.

Swap the left and right speakers, if the problem transfers, then the left channel is out. Theres 5 amplifier sections in this receiver and that one would be defective. A component troubleshooting technician would need to fix it.
