Hi there,

My 6-year-old Technics receiver has recently developed a problem with
switching into protected mode (Overloaded appears on the display) after
being switched on for a few minutes. Now this model ran extremely hot
(couldn't even touch the top of the case) but this was apparently
perfectly normal according to the people from Panasonic and other stuff
I've read online. Unfortunately, I think the years of heat probably
fried something in there.

I've tried the following without success:
-Switch speakers from channel A to B
-Replace speaker wire
-Replace speakers and try channel A and B
-Turning off both channels still make the receiver go into protected
mode
-Running the amp without speakers attached

Since I suspected that this issue might be heat related I replace the
fan at the back of the receiver with a 80mm computer fan wired to a 12V
plug-in power supply. To my surprise, the receiver did not go into
protected mode the receiver stayed cool to the touch. Although this
work around enables me to use the receiver without any problems, I find
it very annoying to have to plug in the fan every time I want to listen
to music. Additional the hum of the fan is audible when the audio is at
low volume.

I though about bringing it in to a shop for repair but most shops want
$80 just to open the case...it gets more expensive from there. This is
probably not worth the money for a 6-year-old receiver. I've read on
the forums that Technics receivers a prone to soldier connection
failure but I'm not sure where to start looking.

Any advice would be greatly appreciated.

Cheers,

Marc Savage
