Ian Lilkendey:
Are you certain that your VR-507 is made by SAMSUNG as your post
indicates? ? ?
I am guessing that you REALLY have the KENWOOD VR-507 receiver.... it
is an excellent unit.

The symptoms you described are most certainly NOT caused by a bad fuse
where the power cord connects nor by a bad internal fuse. Was the line
fuse that you replaced bad? .... If it were, the unit would not even
power up.

Most likely the problem is a front panel tape monitor switch left on or
rear panel missing jumpers or incorrect switch setting for the pre-amp
out to the main-amp.
If all of that is OK then the problem could be faulty components and/or
circuitry that can only be diagnosed with proper equipment and
procedures.
Without proper test equipment, electronics knowledge, repair experience
proper tools and replacement parts this is going to be a repair that a
shop or experienced tech should handle. Parts that "look good" can be
quite faulty and must be tested.
At the very least you should TAKE it to a repair shop for a repair cost
estimate so you can make an intelligent repair decision with facts
instead of internet wild guesses.
For more repair hints and information you should search the website for
