Hi guys, could anyone help me with this.
I’ve got a PSU (power supply/power adaptor) model name PSM88W-213.Its a power supply for bose lifestyle and its not powering on.
From the specs of the PSU, output voltage should be 10v and 44v.There are 6 pins ouput.So when i measure it with DMM.ive got 10v and STB voltage of 1.86v and no 44v.
Is the STB voltage too low?
Thanks.

 

Don't know the Bose product, so just speculating here... could STB be an input to control on/off the +44V? What kind of V vs I curve do you get on the STB connection (with V only a volt or two from 1.86V)? If the current at 0V is a milliamp or so then it is probably an input.

 

It's an adapter that can be replaced easily, it says 10V and 44V no mention of the standby voltage..
