I just had same code. I took off rear cover and unplugged a rubber cap at the end of a long skinny group of a few wires. looks like a charging wire kinda. and unplugged the main plug. I did not unplug the two larger battery plugs. when I plugged them back in firmly everything was back to normal.
sc541/541 is a fixing problem, check if your thermistor or thermal fuse are defective, if yes replace them or clean the thermostat/thermistor. then reset it by pressing the yellow key then 107 then red key hold down for 3sec.after that press copy sp then exit turn off machine after 10 sec on. hope this helps
