JVC RX-515V Receiver - Blown Center Channel

I have confirmed that it is the receiver's output that is blown, not
the speakee.

Is there anything I can check inside - something hopefully simple as
a fuse or thermal breaker?

This is a 20-year old surround sound work horse with plenty inputs
for all my analog gear, and replacements are few and far between.


Thanks for any suggestions on how to troubleshoot!


**If the RX-515V is anything like all the other JVC surround sound
recievers, then it will be extremely time-consuming. They were never
built to be repaired. Throw it away.

The OP is probably out of his league - but I fix this kind of thing all
the time. No problem.

A couple outputs, maybe a resistor or two, sometimes a couple drivers or
a zener diode, etc.

Service info readily available.

Easy.

**Like I said, if that model is like all the other JVC ones I've seen,
it has no removable base plate. Disassembly is not only difficult, but
testing after reassembly is challenging. JVC is far from the only offender.

Oh, yeah.

Most makes and models have been like this for at least about the last
fifteen years. Just have had to deal with it.

For example, you could check my Youtube videos "Yamaha RX-V661 Repair Brief"
or Denon AVR-2307CI Repair Brief" to see the common kind of stuff I do.

The JVC models of this type got nothin' on the Yamaha RX-V2400's etc... now
THOSE are challenging for blown channels, but still - the amp sections are
fairly standard on most of these.

It's things like intermittent DC offset on a single channel that cause the
most trouble for me.
