Question about Onkyo TX-NR609
According to my technician, my onkyo receiver had this voltage fluctuation, which sorted the cpu. It seems a small transfer was also malfunctioning, which I already got fixed. But the cpu has been sorted too and that needs to be replaced. Whenever I connect onkyo to power, the main screen goes on and then standby more alternately and continously, till I press the standby mode. Then it goes to standby mode. If I press any other key after that, same thing starts repeating! Even after fixing the small transformer, I am facing the same issue. Technician seems to be convinced that it is sorted cpu, since it is not passing 12v output! Now I don't know from where to buy this cpu. Any idea? I am not even sure whether replacing that will take care of the issue. Anyone faced similar problem?

SOURCE: no sound from the receiver
Loose connection or cold solder and cleaning problem this is the main caused of no sound..Cold solder issues - each component is soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the receiver turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough.
Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".
Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing....

The output transistors should be replaced in pairs. Also, It may not be just the output transistors that are defective. If you have no experience with these types of repairs, I would suggest that you bring the unit to a service shop. The outputs will run about $15-$25 per pair.

I have found the battery location. It is roughly on the opposite side of the pc board where the display is. It basically faces the heat sinks. It's one of those small watch sized batteries and is soldered but sticking off the pc board with 2 leads. I could see that there was some leakage and corrosion. I still have to figure out what needs to be dis-assembled to get access to it so I can unsolder the bad battery and replace it. This stupid little battery seems to need replacing every 6-8 years! When it dies, it seems to disable the preamp section from passing any signal giving the symptoms that the amps are dead. However, if you try to use the pre-outs to an external amp, nothing. So, my guess is it has something to do with the preamp section. Anyway, that will be my weekend project to try to get at the battery and replace it with "longer leads" so it will be easier to replace in 6 years when it dies again. Great design Onkyo! You dumb-*** weasels!!!! I hate when companies engineer things to break so you are likely to pay them to fix it. Not this time, "No soup for you!"
