[sdiy] Wiard/Blacet Miniwave issue - Help please

[Thomas White]

Hi folks,

My Wiard/Blacet Miniwave is doing something strange now. It is a Rev.0 board. When I power it on, all is well. 30-40 seconds into power on the right most LED's fade to off. Then the rest start fading and "dancing" a bit before all of them turn off. The longer the power is on, the fade out to non-functioning gets faster. Does anyone know what causes this? When looking at the power rails, my supply is solid. The power component PS1 (unique to my Blacet modules), right after the power jack, loses voltage the longer the unit is on. Think it is shorting the voltage to ground? Seems like my likely issue is to replace this part. Thoughts?

Thanks for your help!
