Hi Folks
Have to try and repair a couple of power supplies that are used on Acer Terminator machines, they are ATP-1655, and the same board is used in ATP-1505 as well
They are a small form factor Micro ATX PSU that pushes out 165W for the PC, and there's no easy alternative due to the form factor.
Both power supplies are suffering from bad TEAPO capacitors, one of them has lost the -5V supply, the other was sort of working, but doesn't even start when plugged into my tester box, and it won't power up the PC in less than about 10 attempts, so for now, I've cannibalised a spare machine I have here to get the user out of trouble, but it looks that that PSU is also failing, which doesn't surprise me too much, the 2 I have here have 6 blown 1500uF caps on them, and one also has a bad 220uf as well. The "spare" came from E-Bay, but I suspect that any PSU's from around that time will all suffer from the same problem, so I've got to try and do a repair rather than just throw another second hand PSU at it.
I can source replacement caps without too much trouble, there are 2 or 3 main line suppliers on line, but I'd like to see if I can get a circuit diagram to try and make sure that I'm not missing anything else that needs to be checked or replaced.
I have the necessary equipment to do the board repairs, and enough experience to deal with these units, they're not SMT, so relatively easy to work on when compared to some of the later motherboards and the like.
I need to try and repair them, as the PC they are for is specific, and can't be easily replaced, as one of the software packages on it is tied to the hardware, and can't be easily ported to another machine without a lot of hassle, and the user is planning to retire in a few weeks time, so it's kind of important to keep it going during the transition.
I've tried the "usual" things like Google searches, and the like, but nothing useful has come to light, and having been a long time lurker here, I decided that a post to see if anyone else has had dealings with these PSU's would be worth a try.
Thanks in advance
Steve
