Recently purchased a working Tekken 4 cabinet, which played fine until the green video gave out completely.
Took apart assembly and examined the neckboard and found it to be fried, looks like a overheating problem (same as here: http://forums.arcade-museum.com/showthread.php?p=1081298). The old chassis is a P763, neckboard P719.
I had a newer TV sitting around and scavenged the neckboard and chassis. It is a Phillips 25PS40 - Chassis 25T800 with bundled neckboard.
Can I substitute the neckboard from the new Philips with the old chassis? If so, what is the wiring configuration? Looked everywhere for a manual for the 25T800 without any luck.
Or, should I swap the whole philips assembly in?
Some photos:
Old chassis + neckboard:

Can I connect these 2? Old chassis + new neckboard:
Hope this makes sense, sorry am new to all of this. Am being helped by my friend who is a professional electrician, so I've managed to not zap myself too many times while taking everything apart.
Thanks!
