Hello and welcome to Just Answer. Do you have any tools like a meter and soldering equipment? Does the unit just click and then followed by the standby light flashing when it is turned on?
Thanks,
Paul
yes to both
Hello, there are a couple of possibilities here. First open the unit and look for a small glass fuse if you haven't already. It will be located near the rear right side of the unit. The fuse is usually an 8 amp gma style. Is the fuse ok?
Ok, if the fuses are good then I would suspect the power transformer. Could you standby while I pull the service manual so I can give you specific points to check. This will be using the meter on the ac voltage function.
I have to go to an urgent call out.
i will get back to you later.

Hello, no problem. When you get back to me, please let me know if this is a 120 volt model.
Thanks, I will post some info soon that should lead to a solution.
Hello, Take a look at this board layout and look at connectors cp102 and cp103 I have circled in red.
Hopefully your meter probes are thin enough to insert into the top of the connectors to test for ac voltage. You should have around 240 mains at cp102 and at least 60 volts at cp103. Cp103 has three terminals so use the outer two for this measurement an let me know your findings. Also need to mention these measurements have to be taken within a few seconds of hitting the power button before the power relay switches back off. Have your probes in place before hitting the on button.
Sorry for the delay, had meter problems.
Have checked 240v at cp102, but 0v at the cp103
Hello, you have a bad power transformer. The transformer has a built in thermal fuse device but you can't really get to it to replace it since it is embedded in the windings of the transformer. It is usually rated at 156 Celsius. The transformer must have overheated. Causes of this can be a combination of not enough ventilation as well as too much load from speakers and high volume for a long period of time. It also has an amperage rating a surge can take them out as well. It is a safety device put in there to meet UL and other ratings. Replacing the power transformer will solve your problem. Probably one of the easiest repairs one can do on a receiver since everything is plug in.
If I have fully answered your question, please click accept and feel free to ask follow-up questions as well. I can get you the part number if needed. Transformer will cost about $80 us dollars. I don't know what in your currency.
Kind Regards,

I could do with a part reference, I think I have traced one, but £110 + in the uk
Hello, here is the info straight out of the manual to make sure you get the proper one. I have circled in red.
It is 29 in the exploded view ans E2 designates Europe model so the part number should be XXXXXXXXXX. Sometimes they sub to a different number but this is the number you would order it by. If price seems more it because I am used to the dealer prices.
Thanks for the accept and feedback. Don't hesitate if you have further questions.
