Hello Wayne - 

--8<--cut 

CA>> I took the case off and checked to see if the fuse was
CA>> burned out (somehow?) but it isn't. I'm guessing the front
CA>> ON/OFF is damaged. 

WC> Obvious first thing to check. 

I thought so. :-) 

CA>> It's an HP about 5 years old with AFAIK a micro switch
CA>> that 'signals' the power supply to turn ON/OFF. 

WC> Hmm, I know the H.P. uses a momentary contact on it's
WC> computers but this doesn't make sense to me on the monitor. 

WC> I'd think it likely a simple double pole double throw power
WC> switch. Mind you I've never even seen an H.P. monitor. 

I'm going by the sound and 'light' feel to the switch that it
isn't managing higher voltages directly. 

CA>> Any suggestions as to how I can test my theory and/or get
CA>> the monitor to turn on? 

WC> Well first you've got to open the monitor case and in my
WC> experience this requires a long reach philips screwdriver.
WC> I hacked half the handle from a regular one to reach. 

CA>> fwiw: Doesn't have to be pretty as long as it works. 

WC> If there are two wires to the switch from power and two
WC> leading out I'd say it's D.P.D.T. switch. 

WC> Solder a wire across the appropriate set terminals and use
WC> a power strip to turn it on and off. 

WC> If you're not handy with electronics or familiar with power
WC> line level voltages keep your hands outta there and perhaps
WC> consult someone who is comfortable with line level voltage.
WC> My opinion, YMMV. 

I bread boarded a few transistor circuits when I was younger
and can manage a soldering iron. I could read transistor
schematics and even spot the various sub assemblys at one time.
I guess I'm not 'handy' but am experienced (somewhat). 

I will try adding a jumper to the switch.
