Check the C10 and C11 capacitors on the PSU board, they are at the bottom near the mosfet heatsink. If they are leaking, that is your problem.

It can be seen badly, but it is swollen, domed above and below it is raised above the base.

I haved the same problem on same device,
but solved replacing totally the PSU with another identical,
but I do not have fixed and tested the old.
