![]() To that end here’s a link to the service manual for the receiver. You will need to have a DMM (digital multimeter) and know how to use it as well as knowing how to read schematic diagrams. If nothing is obvious then the various power supplies in the receiver need to be checked and then depending of what the results are, further testing would need to take place. Hi it is not switching on and is getting hot initially the best thing to do is to disconnect the power from the receiver and open it up and check if there is any obvious damage such as burnt out components etc. Given that you gave yourself a shock when replacing the fuse, I am guessing that you haven’t got much experience in fault finding in mains powered electronic equipment and as hazardous, (even lethal) voltages may be involved when testing for the problem, I suggest that you contact a reputable, professional audio electronics repair service and ask for a quote to repair the receiver. ![]() If it still doesn’t switch on, there is a fault in the receiver itself. With the power totally disconnected from the receiver, disconnect all the speaker cables from the receiver, reconnect the power to the receiver, switch on the power outlet (if this is the case where you are) and check if the receiver switches on OK. With the power totally disconnected from the receiver, check that the speaker wiring to the receiver is OK and that there are no short circuits between the wiring connections at either end, speaker or receiver or even from the speaker cable wires at the receiver end to the case of the receiver. The receiver may be in “protection mode” due to a fault condition.
