Hi Jccaclimber,A couple things to check:
1) Make sure the voltage going to the monitor and rest of the computer are correct. If you had to change the taps on the transformer for the motor, you may also need to change the taps for the computer. I got lucky on mine, it was labeled as something like 480 on the cabinet, but was in fact set up for 230 when it came into my possession.
2) Make sure the monitor is good on another source. You should (at least I did on mine) see the BIOS flash by.
3) Consider plugging the entire computer in to a separate power source. The first monitor I swapped in to mine made some very interesting buzzing noises. Once I plugged it in elsewhere that went away. I have not gotten around to hooking a scope up to the original supply to see where it is coming from.
Sorry to dig up an old thread, but do you have a drawing for the transformer pictured in this thread? I have the same one in my machine but I want to check its configuration before I apply power. I've searched everywhere but cannot find a tap pinout for this. Its a 1999 Ez Trak DX.
Thanks so much!
