Re: Yamaha RX-V581 DSP dump files
Hello,
FYI, I'm trying to get in touch with Yamaha audio support service.
Hopefully, I'll get the DSP flash memory contents.
If yes, I'll post these on the forum.
Finger crossed

Re: Asus GL503VD Not charging or powering on
Hello,
Vesko356 is right.
You should first try to short circuit your probes to be sure the voltage is falling and your current consumption is almost 1A.
Then inject again the 1V/1A to the board.
Do you have isopropyl alcohol?
If yes, you can put it on the suspected parts and check which part is getting hot by evaporation.Leave a comment:

Yamaha RX-V581 DSP dump files
Hello everyone,
I'm currently trying to troubleshoot a Yamaha RX-V581 amplifier.
The whole HW looks fine to me but I notice the DSP flash memories are empty.
As a result their is no sound on HPs and speaker menu is not available.
Does anyone has these DSP flash memory content?
The related 2 memories are Winbond W25Q32.
That would help a lot.
Thanks in advance
Best Regards -
