Repair expert needed

[Jerilock]

Hi all. Hoping someone can point me in the direction of a repair tech in the central FL area who would be willing to take a crack at a vectrex. Right now my system powers up and has sound but no picture, just the dreaded dot. I checked the voltages on both ends of the j204 connector those are good, switched out the ic303 and ic304 chips, cleaned the power switch and checked the xyz wires for continuity. All the possible easy fixes and it still isn't working right. I'm really at a loss and don't want to mess it up just randomly swapping out components (the chips were.kind of the last hail Mary). I called every retro game shop in my area and none of thier in house repair guys will touch the thing (or when I talk to them it seems I know more about it than they do). If anybody knows a competent tech in the central FL area I'd really appreciate it.
