now that you had me confused (because of a false interpretation left and right) let's get back to the original question / problem: the pink / brown and blue wire on the left of the secondary side. atm, the two pink wires and the brown one are connected to the 120v terminal, the blue wire is connected to 0. the pink wires run into one AC terminal of the switcher, the blue wire is spliced up later with one wire running into the other AV switcher terminal and the other wire running to the monitor. the brown wire runs into the monitor almost directly. why "almost"? because both the blue and the brown wire are spliced up again, because they also power the lighting fixture. can you still follow me? basically, blue and brown are running on 120V (123V to be more precise), the two pink wires (which go to the switcher) were originally connected to 100V, but right now they are also connected to the 120V terminal - but now i have the problem with the fireworks on the monitor.
should i try re-attaching the pink wires to 100V (thus feeding 100V into the switcher) and only connecting the brown wire to the 120V terminal (don't think this would change anything though). or should i re-attach all three wires to 100V (thus feeding both 100V into the switcher and the monitor) and try to find the "leak" which is stealing voltages on my +5V line? i do get a neckglow when running the monitor with 100V, just no picture. could this simply because the pcb doesn't get enough "juice"?
