make sure your video cable to/from the neck board is plugged into the VGA socket and not the CGA/EGA socket when using VGA. Be sure your computer is set to display 640x480@60hz
your issue could be with the video amplifier (IC 201 - TDA9210) it has a separate video input that it uses for the OSD...

to make things easier, remove the control panel. (undo chain and wires and slide whole thing out as a unit)
disconnect wires and whatnot to monitor.

Looking to see if anybody has a known working Chihiro motherboard they are sitting on.
I have a Ghost Squad game that the xbox board croaked in it. I purchased another board off ebay for it and it worked for 2 days before that board crapped out.
I have all the other hardware and boxes, so if...
some of these weiya made chassis have come from the factory with the HOT and the vertical IC's not properly screwed down. they can overheat and blow out after a few months of operation.
also check R113 if the vertical IC (TDA1675) has blown out, it'll blow out that resistor sometimes too. it...
what monitor resolution is it running at? some medium res monitors don't sync properly and need to have a dip switch on the board flipped to use a slightly different gun timing.
...unless this game worked in it's current configuration before.
OP said the video wasn't his. disregard any information contained in the video.
The gun connect has a small ferrite surface mounted filter on the input (L57). if a large enough static zap from the monitor goes through the gun, through the board and down the line, they can get blown out. (not...
bad sensor board in the gun.
part number 95-1019-00
likely the issue is the surface mounted LM311 IC that switches the output for the computer. it's a couple cent part if you can solder it. i buy tubes of 15 or 20 them off ebay for a buck free shipping
sometimes the optical transistor...
2929 with good bright OSD but dim washed out colors on the video?
problem with ABL system.
change D21 with 1N4937 for a better fix or just replace with same part 1N4148.
OSD manually disables ABL for the duration of the OSD write bypassing the diode which is why the OSD looks great but the...
