Hi all guys, I have this yamaha subwoofer amplifier module model DXS12 that doesn't turn on. There is no sign of burnt parts and I noticed that on pin 16 of UCC2893 there is just 2V and on pin 15 I have 0V, on pin 9 of the Feedback I have 0V.
What could it depend on?
I tried removing PH102 and nothing changes.
The mosfets are good there is no short.
Does anyone have experience with this module?
Thank you guysДобавлено (15.12.2023, 15:57:47)
