Hey Everyone,

If any of you own this arcade or one that uses the same gun technology I'm sure you will relate to my problem. The optic sensor on player 2 of my HOTD2 is not calibrating. Now of course I can buy a replacement optic for $200+ but I did notice three pots on the optic board itself that I may be able to tweak to adjust the optic. I acquired a couple other guns off ebay with similar problems so I have a few optics to play and test with. The only problem is, I cannot locate any threads or documentation in reference to properly adjusting these on the optic gun. If you remove the black cover, these pots are located on the back of the board. I have already tried calibrating it from the arcade menu which did not help. Also I verified that the cables and such are all fine so the problem is defintely with the optics themselves.

Thoughts...

you should know first if it is the gun board, or jvs board in fault.

try swapping with player1. from your description, it might be gun board fault. the fault in this kind of gun is a bit hard to look at. open up the black plastic case. you'll see the front sensor with a protective enclosure.

since you have know that the gun is bad, not somewhere else, you're allowed to opened that enclosure. be very CAREFUL when you opened the enclosure, because there are 4 VERY tiny wire running across the 4 corner of the sensor panel. do not let your finger overlapping those corners, or those wire will be broken. now, take a zoom lens to see them. usually you'll find one or more of them broken. that's what make them can't be calibrated.
