Determine with an external amplifier and a music track with your sony, on the gate leg of the supposed MOSFET. If it gives you audio, it is stable and it sounds good, you can make your adaptation without any problem. Regards.
Dear colleague, my problem is that I already removed the 8 mosfet smd of power and as I see erroneously as the equipment continues to protect itself, protect it two seconds after turning it on.
Study the manual on all the protect lines and their respective intergrades. Then check all components such as resistors, capacitors, etc. Regards
thank you dear jomi I already downloaded the diagram that you sent me exactly that is what I commented to you that the problem with this equipment is that when connecting it the demo is activated and until there is everything ok but when turning it on in 2 seconds disec protected this does it even though in another workshop he was removed all 8 mosfet of power crellendo that it was problems of short departures but still continues to activate the protection any idea that may be causing this protection you would like it friend jomi
if I could disconnect the amplification card completely x it would have been a save but it is not possible since in this card there is also the pre as well as the power supply of the main control
Luis then do these steps (they are from the service manual):
1. While displaying the PROTECT message on the display.
2. Press the PLAY / PAUSE and STOP buttons simultaneously.
3. A message should appear on the display.
These are the possible messages:
AMPLIFIER
MTK POWER
POWER SUPPLY
FANBLOCK
ok buddy thank you very much excuse me for the delay tube I will try some problems and I will tell you
