Are there any readme files on Power supply for a tron unit? I am not sure how to test it oe know what voltage should be or how to adjust.
 
Thank you for the links, I just found the schematics online.
Just wanted to check voltages as I was reading how voltage drop can cause crazy things to happen and with this vertical synch problem I have going, wanted to make sure it was not just this. Does anyone know if there is a vertical\horizontal synch on the video board as well? The synch on the monitor seems to be ok, but I have to find my logic probe to make sure. Will be doing a cap change next, have also ordered new ribbon cables for the boards.
Making me scratch my head to much, having to work 60+ hours a week does not make it any easier to have the time also.
 
OK, got some troubles.....Here is what I wrote out, meaning 1st down=1st column on the connector and say 2nd row well look at the plug and if you count left to right this would be #5 pin. I hope this is not to confusing.....

Should Be Mine
__________________________________________________

+5v Red 4th down middle row +5.51v

+12v Orange 2nd down last row +11.66v

+5v Red 4th down last row +5.51v

+5v Red 5th down last row +5.51v


2nd connector
___________________________________________________

+12v Orane/Red 1st down middle row 0.00v

+12 Orange/White 3rd down last row +11.67v

+5v Red/White 4th down 1st row +5.51v

+5v unreg White 5th down 1st row +10.20v

+5v Red 5th down 2nd row +5.51v


I also found the Red/white stripe wire (+5v 4th down 1st row) was broken and out of its socket. The +12v Orange/Red that has 0v, where to start looking?

Ok, where it says should be mine, I wrote as to the left side is what the Voltage should be and to the right is what mine is, do not know why the words are running together.
