Thanks for all the suggestions guys. Here's something really odd --
today I was fiddling with the radio (MW was dead of course) when I
pushed the dial light button firmly and *poof* the MW came back on. I
shook the radio and bumped it around in an attempt to get the MW to cut
out, but it stayed on strong. I pressed the dial light several times,
and switched the band selector back and forth, but nothing seemed to
have any effect on the MW (it stayed on). I then turned the radio off
for about 10 minutes, and when I turned it back on the MW was dead
again. I pressed the dial light button a couple of times, and the MW
returned! I've repeated this dial light "fix" several times throughout
the day.

OK, I'm no radio expert, but how could a dial light effect one band like
this? Better yet, how can I fix or track down the problem? Any more
thoughts are appreciated.

Dave.


Turning on the dial light could create a voltage transient in the
receiver's power supply that may be temporarily repairing a defective
component such as a transistor. See if you can determine which active
components (transistors and IC's) are used only for the MW section.
