| Check if the speaker output has any DC voltage present when it shuts off.
Also check if all voltages in the PSU are present and within limits of value. |

| also if you use a 8-9V power supply instead of 12V the fan would be much quieter...
Or you could use a duct and baffle setup if you really are concerned about the noise... |

| There is a convienience outlet in the back, if you plug the power supply into it, the fan will come on and go off with the unit.... | |

|
| 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 cooked 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 off 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 (which only come on with the volume at %75) 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 and 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 vibration 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. Any advice would be greatly appreciated and if anyone has the service manual for this model I would be very gratefull. Cheers, Marc Savage |
