Re: My XL7 won't power up

2006-09-09 by gonzinigonz

Im looking into now. Ive just opened up my XL and will meter a few 
things to see what happens.
Quick look at those other SMPS's on powerdecs site arnt the same 
after all.
Theirs seem to be triple rail type so hence the less cables..
The XL has got 4 :-

    3.3v
      5v
    +15v
    -15v 

And 2 other lines that do the remote power up/down.
This has more incommon with a ATX PC supply at the moment. (now 
theres an idea..)
l'll get my scope on there and try to reveal once and for all the 
mystery of the PSU...
