Hi team,
I'm having an issue with a Mak Strike amd RGB connection..
First of all,I have to mention I removed the SCART connector (as I do not have any TV/monitor with scart here in the US)
Tha's the only mod I did, I can assure you the PCB is clean and I did not ruin anything, I used a desoldering gun which worked flawlessly.
I made a cable taking R,G,B Sync and ground (checked continuity to Jamma video ground pin) and connecting them to the right pins (on both 1084s and the cabinet monitor).
Now, when I try to connect different neogeo boards (2 slots, 1 slot etc..) on different monitors (one arcade in the cabinet and a 1084s-d2 commodore) I get the same issue.
When the supergun's main switch is *off* (but PSU is connected to outlet and to MAk Strike 12v,GND,GND,+5v)) I can see a blue pattern (attach 1084s...when I connect it to the arcade monitor it starts hissing but no blue lines:/ )
When I turn the supergun on, I can see the game (so sync seems OK) but it seems missing red and I can see a blue pattern moving (this on both moniitors, attach, never mind the bank error message, with other 2 boards the game starts perfectly, same blue pattern and missing red)
The power supply is new and is giving 5.0v measured by the MAk.
..it seems strange to me, as the Mak strike is a passive element?Any idea? Maybe one of the pots is gone?
Thanks!
Edit:
tried to disconnect the rgb sync and ground wires one ofter the other and here the result:
MAk main switch off:
R,G or B wires disconnected (until I had only sync and ground), similar "blue" lines patterns ,a bit different pattern, same color
removed Sync (only ground connected) same issue as above
disconnected the cable, no issue (obv)
I recall I disconnected only the video ground once (RGB and SYnc connected), and had the blue pattern anyway.
...?
