[sci.electronics] wyse terminals

Greetings,

I have a few wyse 50 terminals which have gone bad.  All the problems
come from the video board.  Mostly, there is 5 volt but the 24V is gone.
I've checked the infamous C120 capacitor and it's ok.  I've also checked
all the solder joints and connections and it's ok as well.  Can some
experienced wyse terminals repairers give me a few hints on which
components to inspect?  The way they all fail leads me to believe that
it's just one component that's causing the problem.  Thanks.

Harold
