I just bought a house of the dead 2 at auction and it might need new guns.can someone tell me what kind of guns I can replace the old ones with or is it possible to repair the originals
 
Did you get this at the Newton auction? I stopped through real early but didn't see anything of real interest. Do you know what that turbo cabaret went for?

I'm having a similar problem with a gun I have for LEII. Happ seems to be one of the few options.
 
common failure point on these is in the optic itself on the gun's board. after repeated drops eventually one or both of the legs will break (really only 1 break will kill the gun in all fairness :)) and under some circumstances you can desolder, cut the legs even and resolder them, unless it's a very high break towards the optic, then you'll have to replace that part. the gun boards themselves can get somewhat pricey... I've had luck finding them relatively cheap on ebay years ago. I don't know anything about finding the replacement part for the optic itself... maybe someone else knows.

other failure points will be wire breakages, which I've replaced entire wires in these guns before, so it's entirely doable. the other will be that the connector that goes to the gun board popped out... this was so bad on one particular gun on our House of the Dead that I said fuck it one day and just hardwired all the wires to the board by soldering them to the joints of each pin. I don't encourage doing that however... although it's been successful, I can foresee it becoming nasty one day, and that was during my early days of doing tech work lol

nothing a little silicon could've done the same friggin thing for.

also if you have motion in the gun in the gun test, but the trigger won't work, you're probably looking at either a bad switch or something mechanical came undone in the trigger. either way, under any of the above circumstances, you'll have to open the gun up to see what's going on. I STRONGLY encourage that if you don't already own a hot glue gun, to purchase one, if only for the purpose of hot gluing the nuts to the bolts that hold the gun shells together, because if they're the acorn nut variety, you're going to be doing a lot of tossing them into the hole and hoping they line up right... and then holding them on to make sure they don't fall out when you put the bolt back in. lol

last but not least, if you're huge into cosmetics, if your gun shells look like they've been through several wars or they're the wrong colors or something (player 1 is blue and player 2 is red) you can always buy replacements from Happ.

I think that's everything.

otherwise the more longterm alternative would be to replace the damn things with Happ .45s, but that's not "authentic" and under some circumstances the holsters on these Sega shooters don't necessarily allot for those.
 
Thanks for the info! So player 1 gun harly picks up on the screen and when it does it moves all around. Second player seems pretty steady but darts off every once and a while and wont go all the way to the left sometimes. So I switched the sensors in the guns and it did not change anything. Both guns the trigger works. Im kind of stumped. Could it be a problem other then then gun?
 
The happ guns will only work on HOTD and not HOTD 2 (see link below). You might have one of the LED Gun Sense Boards around the screen bad. If you look at the screen sensors in a dark room you should see 2 dim lights in each one. There are 12 of them.

"Allows Suzo-Happ Optic Guns to be uses on Sega games
Can be used on Virtua Cop, Virtua Cop 2, House of Dead 1
Will not work on Lost World or House of Dead 2 "
 
Not sure why there would be 4 lights on some. They only have 2 LED's on them.

If you only switched the sensors in the guns. Try to swap the gun connectors inside the machine so the left gun is on the right input and right gun is on the left input. That would help tell if there is a gun / gun cable problem(problem moves to the other side) or a Gun I/O board / LED sensor problem (problem stays the same).
 
oh, I have no idea how or why I neglected to mention this, but if your +5 at the power supply is too low it will cause the guns to not track as well.

considering it's a NAOMI game (according to our very own KLOV), you can't go above 5.10V at the main board, or else you'll start nuking it. if you want to meter this, pay mention that Sega's wiring color scheme is completely ass backwards from everyone else's.

yellow = +5
red = +12
brown = 3.3
white = ground

jam your meter probes in those pins on the back of the main board, make sure your +5 is 5.10V and the 3.3 is 3.30V exact.
 
common failure point on these is in the optic itself on the gun's board. after repeated drops eventually one or both of the legs will break ....

other failure points will be wire breakages, which I've replaced entire wires in these guns before, so it's entirely doable...

which legs did you mean?? any photos?

by wire breakages, you mean some small colorful wires that connecting the sensor bd? if that's it, then yes, usually because of the steel pipe wore off and tear off the rubber shield.

the sensor board itself have 2 pcb part, one is optic part, the other is pre-amp part. the optic part is easy to identify, the most front part of the sensor. it is usually protected within plastic enclosure. now, i'll let you know a little secret. do NOT ever open that enclosure (optic enclosure) if you don't know what you're doing. because in normal eyes, inside of it, there are piece of square optic sensor that are wire-bonded in 4 corner of it, which can not be seen without zooming. this wire is not ordinary wire/cables. untrained tech would try to open it and clean it with some ear bud/cloth carelessly. those act will absolutely destroyed the wire bonding and of course, the sensor will stop working properly.

hope this helps to prevent any unnecessary stupid act, like i did (before i knew).
 
yeah, I never knew House of the Dead 2's guns were different, I actually had to look up what boardset it was on. most of my information remains the same though, it'll either be wiring, physical damage on the inside, voltage, etc.

good luck to you all
 
I don't know anything about finding the replacement part for the optic itself... maybe someone else knows.

Phototransistors are somewhat standard. This is used on Big Buck Hunter guns and most Happ "standard" gun boards, but it may not be an exact replacement for LE2/HoD2, I'd need part numbers read off the original to be sure.

-E- Nevermind, you swapped the sensors already. I'll just leave this here for a Googler passing by.
