Hello,
I'm working with a Spectroniq model PLTV-3250 LCD monitor.
It uses an FSP194-3F01 power supply.
The monitor won't start, there appears to be a standby led on
the front but its not lit. In the supply I am getting DC voltage at one of the
leads (about 160V) of all of the heat sinked transistors except
one, so the supply is live, but it wont start. I found some caps
that were swollen at the top, so I replaced them along with some other
smaller ones just for good measure. Also I replaced a shorted surface
mount transistor. Then I went through and checked other transistors and
diodes which all checked good. Just wanted to find out how to rig this
supply so I can run it on the bench. That way I can see if I still have a
supply problem, or something else in the monitor. I've seen different material
on how to manually start a computer supply but this one is a bit different.
I'll post some pics so you can see what I'm working with.
Thanks.
