Lost World, guns not registering

[Sarver Systems]

I'm not really sure where to start with this one.

The game works (except for the audio, but that's a different story), and has a beautiful picture.

However, when firing the gun, I get the white flash on the screen, but I don't see anything being shot on the screen, and I'm not sure if I should see a crosshairs on the screen or not.

Looking at the game inside, I can see a ring of IR emitters around the screen. How can I test to see if these are outputting any IR light? I tried using the camera on my phone, since I can see the IR light emitted by the remote control for my TV, but I didn't see anything. I'm hoping for a more technical, definitive method of testing the IR emitters. I've also got a 2nd complete set of emitters I'd like to test.

How would I go about testing the guns? I see there are multiple versions of these guns for this specific game. Unfortunately, I don't know what version the game itself is. I can see by the schematic addendum that the 1 gun is one version, and the other gun is a different version. I can handle changing them to the correct version, if I knew what the correct version is supposed to be. The manual doesn't show any details on the schematic of the gun ports on the board.

Any help would be appreciated!

You really need a multi-meter to start with, not a camera.

From your description it's not clear which you have. To be honest, I long thought this cab was Japanese only and never made a U.S. release. I was kind of surprised to see it on KLOV as a Stateside release. So I'll make some assumptions.

According to the KLOV, this cab is interchangeable with "The House Of The Dead" cabinet. So it stands to reason the cabinet information for one can be applied to the other. Specifically the LED's. According to this version of the manual on page 47 there should be two LED's at the bottom that light up indicating a functioning array.

If there is no light, then I would see if there is power to the array by following the leads back to the source and measuring voltages with the Multi-Meter. Look for a fuse or burned traces on the board where the LED array plugs into.

I don't have any more advice as I haven't looked at the schematic in detail yet.

I have a House of the Dead in the same room, but there is no way that it'll be used for testing purposes. So we can rule that out.

There is an array of these IR LEDs all the way around the monitor, not just 1, like a Deer Hunter game has.

If I'm understanding you correctly, one of the IR LEDs under the monitor will have a set of diagnostic LEDs on it? If so, I'll have to check that over real close.

I think you misunderstand me. I never said to use a HotD cab for testing purposes, how could I since you never mentioned as such in the original post? What I said was,

Maybe someone had the same problem with their HotD somewhere?

I gathered that from your original post. No need to repeat it.

I lied. I looked closer at the manual as I wasn't able to locate a proper schematic. The array is made up of modules, each with two LEDs? There is a set of wires coming in on one side and out the other? They must over drive the crap out of the poor LEDs to even bother mentioning replacing them.

You could try the camera on the HotD cab and see if you have light, if you do, then you know the LW cab is OOO. Otherwise, you should get and use a multi-meter. Diagnostics is so much easier with a basic multi-meter. It gives you basic information about voltage levels and the like. LIke i mentioned previously, you use the MM to probe for good voltage levels. You'll need to explore the wiring harness to determine how the LEDs are wired, from that, you should have an idea of what the correct voltage should be.

That's where I would start. Make sure the LED array is actually working before you start looking at the rest of the system.

I've got a multimeter, and I do know how to use it.

THe schematic is awefully small, so I'm not sure what voltages I should be getting at the connector on the board where the daisy-chain of IR emitters plugs in.

each of those sensors you should see 2 red dots lit-if not check your wiring to the gun board

did this just develop this fault?

if the sensors are all lit then check the gun cables are not broken and check the gun sensor itself,there is a copper shield that is soldered at 2 points to the sensor circuit board-check this is not broken off

this game is sega mark 2 gun system

[Sarver Systems]

There are red LEDs on each of the sensor boards? I'll have to take a look at them again, I don't recall seeing any, let alone any that were lit.

I did take the guns apart, and I saw the foil you are referring to. Everything in the gun looks OK, but the plugs on  the guns are wired differently. He got one gun from some other game, and the other gun from some other game. Both are for Lost World, but from some other Lost World game.

ok best to post photo's of the guns,happ did make a sega type 2 gun replacement so i wonder if you have that
as long as the gun sensors are the same type there will no issue there

but yeah you should see 2 red dots on each screen sensor

i have worked on a fair few of these type machines and they are very reliable
