RE: [xl7] Please HELP! My MP7 wont switch on!

2012-01-25 by barnabyandrews@colouredglasses.co.uk

Thanks for the quick response!

I have tried the hard switch and still nothing. I generally leave the hard
switch on and use the soft one, as its in a rack, however when it gets
switched off at the wall and then switched back on again it would power up
without touching the soft switch this is how I suspect it was turned on
accidentally. Ive had a quick look through the archived posts and it seems
that replacement power supplies are not available?? (please correct me if
I'm wrong) So I guess I've gotta mod an ATX PSU, before I do this though is
there any way I can tell if this problem goes beyond the PSU i.e. how do I
tell if my main board is fried or not and whether it is worth trying to fix
the psu??

Many thanks for any and all help :)

can tell you more about that.  Before you go that route, have you tried the
hard switch on the back of the unit... sometimes flipping it off with the
hard switch and letting it sit a few minutes before powering it back up can
correct this issue.  For whatever reason, on some units, if you always use
the soft switch on the face/front of the unit it will occasionally not
power up.  If it does happen to be an issue with the power supply, look
back through the archives... somebody posted awhile back how to mod a
computer's 5v supply to power a unit... also check erpelectronics.com, they
might have one.  However, unless you noticed your unit getting really hot
recently, it probably isn't the power supply... When I was going all
hardcore with mine, I used to hardly ever turn it off... it would be on for
months, and never had any issues with the power.

There is a possibility someone switched it on by accident while I was away
and if so then it could have been left on for a long time. Please can
someone suggest how I go about fixing this as I love this purple machine
and need to use it.. Does anyone know if there are any internal fuses that
may have blown or
