Sansui amp problem

I have a sansui RZ-2200AV amp which has just stopped outputting sound, the only way i can get sound out of it is to turn it to full volume and i can just hear some sound. I cannot change the input, it won't respond to the buttons on the front and constantly has what looks to be V D on the display. The backlight for the lcd has also stopped working.

This sounds like you lost the 5V supply. If you can solder, look for bad solder connections around the voltage regulator ICs. These look like transistors (3 legs) and may be attached to a heatsink. They will be marked 7805 +/or 7905.

Stereo Amplifier fades out. My Sansui dolby pro


No that's how to describe a problem, folks - with details. Using internal FM as the source is always the preferred way of troubleshooting system-wide receiver audio problems (no cables or setting in the way).

Does the sound come on immediately with power and then fade or is there a small delay while the electronics stabilize, a click and then sound that fades?

The fizzle probably means something is rapidly overheating or a capacitor is malfunctioning. If both channels do it, I'd suspect a common power supply problem. Can't help much more than that.
