SOURCE: F61 error

whats wrong is that whilst the power amplifier is running and the system fan fails due to internal resistance of the fans resistor the main power amplifier overheats causing the main power NPN transistors to turn off the system power by the use of a logic AND gate that causes the error code F61 to appear and turn off the systems power supply. The solution is simple the main transistors are removed carefully and their terminals are shorted using a screw driver. the transistors contains a little voltage which activates the AND gate to shut off the power supply and the error F61 appears. make sure the transistors are replaced correctly and solder very light. If the problem still occurs provided that all transistors are fully shorted(all three terminals) and properly replaced then the radio should be taken to a professional

Need to know how to get rid of F-61, cause my stereo is completely dead...model# SA-AK78

I had this problem! Panasonic 5CD Hi Fi. I opened the case to get a look at the circuits and noticed a covering of dust on the components. I took the hoover to it and an initial inspection could find no glaring problems, such as burnt PCB! I decided to power-up and to my joy the machine whizzed into life. Problem solved!!!!!!!! BTW, this unit is at aprox 10 years old and still goin great!
