Messed monitor. Any help?
« on: August 24, 2004, 02:52:12 pm »
I'm so embarrassed :-[.  I tried the monitor hack, and I think I fried my monitor.

What I did:
I connected the red, green, blue, and ground pins to 1,2,3, and 5 respectively.   Then I connected the negatve horizontal sync to pin to pin 13 and the negative vertical sync to pin 14.  I plugged it all in and the monitor blew a fuse.  I replaced the fuse and tried plugging in the monitor without the hack connected.  It blew the fuse again.
My monitor is a WG k7131 and is set up with a separate ground pin next to the negative sync pins.  Should I have connected that ground to pin 10?  Can someone tell me what I did wrong and/or how to fix this constant fuse-blowing?

Sounds like you have a bad part on the monitor and not the cable hack you created.  The signal wires coming in only have 1-5 volts of juice and very few amps, so unless you hooked your RGB to a power bar somewhere i doubt thats what it was.  When my Wg 7193 was blowing fuses, it was a bad flyback.  check out randy fromm's flowchart for your monitor and see where he recommends starting and go from there.
its better to not post and be thought a fool, then to whip out your keyboard and remove all doubt...

How can I tell if my monitor has a built-in isolation transformer?

Your k7131 (a.k.a. the k7000 series) REQUIRES AN EXTERNAL ISOLATION TRANSFORMER connected to it.
