I am trying to solve a power supply problem
When the organ is turned on it will not always power up
However if you tap the little 24v relay on the power supply unit, there is a loud pop and everything starts working
I have de-soldered the relay and installed a brand new relay, but exactly the same fault

I have now checked every single joint on the power supply board for dry joints

Does anyone have any ideas or had experience of this problem and how they overcame it

The unit PU number is ND3051F

Any help will be greatly appreciated, thanks
