Re: multisync CRT monitor horizontal sweep

The monitor is an NEC MS75 (MultiSync 75), dated August 2001. I doubt
the electrical specs are on the relay. I was hoping the part number
would be on a parts list. Otherwise I can probably locate the suspect
relay by sound if I can run the monitor without the back and base.
