Picked this up last week. It was used in an office setting and "one day it just wouldn't turn on". LED on the front of it shows no life. I've got it opened up and the first thing I checked were the 2 large rectifiers on the power supply(this was the problem on a Sharp I fixed a few months ago).
Now, either there is something odd happening with both rectifiers, or my meter is on the fritz...supply voltage always reads good at about 160vdc, but the 2 drop legs sometimes read good at about 80vdc, but sometimes I get no reading, and it seems to be random and it's happening on both rectifiers...like I'll measure once and it's good, move the meter probes around to different legs, and all of a sudden there's no voltage on the drop legs, but always shows around 160 on the input.
Shouldn't a rectifier always be "on" and always have voltage on all legs, except for ground, obviously? And why are there 2 of them? Part number TS10P06G.
Thanks.
