good night yoreparo companions, I have in my workshop a sony hcd-gt444 team which apparently works normal in all its functions, but at certain times when one turns it off it disconnects from the network and I come back and turn it on; it gives the symptom that it runs out of sound ... only heard by the subwoofer so the tachometer no longer moves the fan that is next to the transformer either but otherwise works normally does not turn off or hangs if I rise to the maximum volume level Medium is heard. When leaving it for a good time without working again, the equipment is turned on and starts with sound, it is something like sometimes if it sounds and sometimes it does not, ... I do not need the fault very well, I have already ruled out several elements but the problem continues.

good morning, of course the first thing I did was reset it, the reley activates and deactivates normal, the voltages of the amplifier IC are present; even cancel some parts such as the cassette etc. to discard short but nothing in fact already takes a few days without giving the symptom, It is difficult for me to find the fault if the equipment is working well (apparently)
