Ahem, the standby light tells you the power supply is fine.


This is the same problem the other poster talked about, and it is affected by heat, but his is not the solution. Over time, as things heat and cool, they expand and contract. Everything does. It is part of physics. Think of the metallic parts in your stereo like you do a paper clip. Bend it back and forth a few times, it work hardens, and breaks.

The soldering points have developed a crack that expands with heat and may re-contact when you first turn on your receiver and the points are closer (colder).



Unplug the receiver, pull the top over, pull the front panel, pull the 3 knobs and remove the front circuit board but do not unhook any wires, Download a service manual for free and start with pin w19 and work your way across the backside of the display with a magnifying glass, or better yet, an opti-visor.


You will see a soldered pin that has a dark outline about midway through the solder. This is a crack. Get a decent soldering iron and re-heat it, or even better, some lead free rosin core electronics solder and add a tiny bit to the post.


Re-assemble and plug it back in. If it doesn't work, then you may have more than one. If all of this doesn't work, then take it apart and use the parts as an art project.

I fear that there's no easy fix. Sounds like the power supply or the board which controls it is bad. If you're not an electronics repair person, it'll need to go to a repair shop.
