Hi all
I am trying to get two WG monitors to work - a 4900 and a 4613. When I turned the 4613 on, I saw some smoke near the windings and heard a horrile crackling burning sound. I immediately turned it off and as a first step I am thoroughly cleaning it because it is absolutely filthy. All the boards have a layer of grime on them. But there are two connector thingys on the sound/power board I need to know how to undo (see pic). It's probably simple, but I don't want to damage them for the sake of asking an obvious question. So, do these just pull out, do I squeeze the bottom halves together and pull, or what? They don't seem to unscrew, but the top part pulls up a quarter of an inch while still remaining attached to the bottom part.
Next question: having read the thread about cap kits putting a strain on other, older components, would you do cap kit on this after it's been cleaned or reassemble it and try it and see if the burning sound was just some of the crap (I haven't found any signs of burnt components yet)?
Final questions (for now): when I tried the 4900 without the game boards plugged in, I got neck glow and I got a whole lot of pretty purple sparks coming out from under the anode cup but no sign of anything on the screen. I should still see the screen light up even without the boards plugged in, right? If so, and after applying dielectric grease to the anode cup, where can I jump to on the Randy Fromme 4900 flowchart? Should I install a cap kit as the first step?
Thanks very much, Dominic
