Hello everyone
The display I am troubleshooting is the same one mentioned in this thread:
https://www.badcaps.net/forum/showthread.php?t=10851
I am trying to repair a faulty Xerox XM3-22wB 22" Monitor.
Upon applying power to the unit, a large repetitive clicking sound is coming from the speakers but there is no picture and no LEDs lit up.
I have replaced all of the capacitors on the output side of the power supply, but the problem still remains. (Not touched the caps for the backlight though).
Further fault finding:
Upon applying power to the the power supply board disconnected from the main chassis, both power level (14V and 5V) appear Ok and stable.
When connecting the power supply board into the main chassis, the 14V is fine but the 5V level is dropping to about 1.8V.
All output capacitors (there are three) have been replaced on the 5V output side.
I wondered if anyone could assist any further please, as this is where I have got up to. The person I got the monitor from said that it was working but had been stored in a shed for about 2 months - Maybe it suffered from cold/damp during this time?
Thank you for any assistance
Ken

But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...
