I have a case of psr 323, I transferred a working mother board to another, when I switched it on, the sound went off and the song volume was no long functioning.
Please what should I do?
Thanks guys.
Do you mean a PSR-E323 ?
Yes It is. Yamaha E323
Bit of a wide open statement - what IS actually working … LCD OK? Keys OK - ie keys show on the LCD … etc etc ?
Yes, LCD displays and keys shows on the screen.
Have to look at the power amp now
CN105 on the PSU/amp board is the connection to and from the volume pot. if you touch pin 4 or 5 with a pin you should hear a 50Hz rumble through the speaker(s).
If not we have to look further …
