Hello.
I have old recciver Yamaha RX-V775 where now is no sound ~1-2 minutes after switching on(Pure direct working always).
I dissasemblied it and found, what this is problem in DSP chip D80YK113CPTP4. If i try to heat it with hair dryer - sound on and icons on display is too, if i tried to cold it with air, no sound and no icons. At work we a resolder this chip, but without success. I think what i need to replace this chip to a new. At Ali i found my chip with price ~30 eur and newer version D80YK113DPTP4.
Now i trying to find information - can i just to replace broken chip to new, or i need flash to new chip some firmware?
