Re: unit power up
If you want to have your system serviced, take it to the Sony authorised servce rep. This unit is mainly serviced at the board level. Independent service shops will not have the necessary setup and boards on hand to properly service your system.
It is very common that the power supply, and or the output stage fails in these systems.

F61 means that the power amp has something wrong with it.
It could mean the IC501 has failed or that there is something wrong to the power supply to it.
The good news is the service manual is free online. You can get it by simply putting the model number into google and searching for the PDF of it.
pop cover plug in with med to light pressure on the heat sink press down gently and push one way just a tad , press power , see how long to shut down. do same other direction. what you should find is that the solder connections are bad and need to be redone. this is not the first pan. that has had this problem, some of there other stereos do to.
F 61 error means the failure of FAN
most probably dust in the fan made it to stop working so clean the dust
and connect the fan to an external supply of 12v(using red and black
wire) for 5 minutes and reconnect it to the unit otherwise replace the
fan with new one.
Surely this will solve the problem.
my dear friend. this error message means something is broke on the audio power.
the unit give that message when the chipset find fix current or signal on any audio channel.
the most common means you have to change the audio amplifier unit. sorry but i know is the true.
Hi, F61 usually means that the unit has some sort of DC error internally. One of the amplifiers could have failed. The HT70 is an older unit and dry joints around the voltage regulator and power amplifier is also very common. Also check that the fan is in good order.The unit will most likely have to be checked by a professional tech.
I have just struck this problem on a friends unit and here is what I did
Disconnect DVD player and all accessories and connections
Problem still occurs
Open machine ( remove three screws from back and slide top cover off. inspection of the inside top cover shows a black patch just above the fan unit
manually spin fan
power up unit and f61 no longer shows up
I think this miaght be a problem with the fan not spinning up at start and the machine then shuting down
I will fit a new fan and see what happens
