Fat Frog PSU problem

[richard_cooper]

I have a Fat Frog with what I assume is a PSU fault. Basically if power is applied to the PSU with the frog attached than the desk will not start, however all the LEDs will glow ever so slightly. If I apply power to the PSU and then connect it to the desk the desk will start and work fine?

 

Am I correct to assume that this is a PSU issue, and therefore simply replacing it will help or is there likely to be more amiss?

 

Thanks
