Ahh, yes. That would be perfect as the screw mounts make the panels a little thick for MVS-U4. Still though, it works. A little snug as the marquee bezel goes over the LED panels, but it works.
Question: I noticed in your video you are drawing +5vdc from the motherboard. Is that right? So pins 1 and 8 on the motherboard are GND and +5VDC respectively? No need to draw +5vdc from the PSU?
Ahh, k. Shoot, it was frustrating. Seems adjusting the brightness controls when the cab is on does nothing? I must have left it turned full clockwise. I'll mess around with it a little more. For the brightness adjustments to set the changes, the cab has to be power cycled?
Great product nonetheless. Will last much longer than the original ELA panels.
did you not receive instructions ? you have to press test to change the brightness this is so it's not always checking the pot all the time and it could fluctuate.
The new control board should light up panel 1 through to 4 and then go back to 1 and wait for the neo geo to switch panels.
You can test this by removing the game carts and pressing player 1 to enter test mode.
Mode 1 = Neo Geo normal mode
You can set the brightness of the panels by pressing Test.
Mode 2 = 1st panel is on and you can set the brightness level.
Mode 3 = All panels off.
Mode 4 = Test Panel 1.
Mode 5 = Test panel 2.
Mode 6 = Test Panel 3.
Mode 7 = Test panel 4.
Mode 8 = incoming BCD data
Press test to return to mode 1 or reset.
and yes you can take power from the ELA port on the NeoGeo it's directly linked to 5v on the edge connector.
I attached the instruction PDF and you can see the connections too red = 5v and black = gnd.
If you want to cut of the screw mounts to help with fitting it's fine
