DO NOT USE MOBILE / CGNAT DEVICES WHERE THE IP CHANGES CONSTANTLY!
At this time, it is unfortunately not possible to whitelist users when your IP changes constantly.
You may inadvertently get banned because a previous attack may have used the IP you are now on.
So I suggest people only use fixed IP address devices until I can think of a solution for this problem!

Mega ST2 psu failure
I got myself a Mega St2 and it doesn't power up at all, nothing at all happens. I thought I would start with the PSU. It has a Mitsumi sr188 Psu. Will the PSU start without load?

Re: Mega ST2 psu failure
No, you need to load them for them to work properly. Lots of info on my site about PSU's..Erikswe wrote: 23 Sep 2018 12:35 I got myself a Mega St2 and it doesn't power up at all, nothing at all happens. I thought I would start with the PSU.

Re: Mega ST2 psu failure
Thanks for the fast answer. Well I did read there and it says the PSU don't work good with out load...
I have taken it out of the ST. It looks very much alike the sr98

Re: Mega ST2 psu failure
Does the PSU tick by any chance? I have a pair of Mega's with odd PSU faults, so I'm curious to know.
The 12v fan on mine won't kick over unless the PSU is disconnected.

Yes, ticking is normal. See also here: https://www.exxosforum.co.uk/forum/viewt ... ?f=9&t=937

Re: Mega ST2 psu failure
Without hijacking too much, PSU plugged in - no 5v, no fan spin. PSU unplugged 5v OK and fan spins (no tick). This happens on two PSU's and two Mega's, one PSU is recapped and had the rectifier bridge replaced, one not. If I plug in an STFM PSU - no problem, Mega's work fine. Just plain weird.

Re: Mega ST2 psu failure
I think someone else had the same problem, can't remember what thread is was though.. probably bad solder joint on the PSU somewhere.

Re: Mega ST2 psu failure
I wouldn't have thought it would be a bad joint on two PSU's. When the garage warms up a bit I will get in and have a closer look. ATM it is pretty cold in there. :D
