I hate Lethal Enforcers cabinets. They have been nothing but bad luck for me so here goes my novel with a few questions mixed in.

I have one at home right now that I picked up from a KLOV'er and it was working when I got it home but the monitor (K7000) had really bad gausing (sp?) in the top left hand corner of the screen. I couldn't shoot anywhere on the left hand side.

Day two the power supply died. I replaced it and still had the gausing issue. I degaused it and turned the flyback screen control up a bit as that was the only way I could shoot all the corners of the screen. Played through the game and shut it off when I went in for lunch and when I came back out the monitor wouldn't come on. The game was playing blind. Pulled the chassis and and foudn the R92 was cooked and open. Replaced it and the game plays again. The remote adjustment board did not have the plastic cover on it and I had set it down on top of the coin box while I was adjusting it which brings me to my first question.

Q: Did r92 burn up because something on the remote adjustment board shorted or because I turned the screen control up on the flyback?

Now that the game plays again (I should have capped it while it was out), the gausing is back again. I did move the cabinet in my garage and it seemed to come back when I did that. I checked the degaus wires are plugged into the chassis and there are no speakers hanging out of place or anything.


Q: Why does this monitor keep gausing really bad in the top left corner (mirrores so bottom left I guess)?


I have already sold the cabinet to someone and am afraid that he is going to get it home and won't be able to play it because of the gausing. I guess I could send my degausing coil home with him and pick it up later but I would rather fix the problem if there is one. The groudn wires and everything around the fram of the tube looks correct and tight.

Thanks for reading and any help here is appreciated.
 
Does rotating the cabinet 90 degrees make a noticable difference in the discoloration?
 
Degaus the hell out of that portion of the monitor frame. If it still comes back in the same place it might be screwed. I had a 19" WG that wouldn't stay degaussed for more than a couple hours after a manual degaussing. I never tried swapping frames, but that might work, if the problem is a magnetized frame.
 
Crap. So yesterday I degaused it and it looked pretty good. Today when I turn it on it is back. Is it typically the frame getting magnetized that causes this. Is it just going to be the monitor frame that mounts to the cabinet or will it also be the metal banding and frame that wrap the actual tube?

Thanks
 
Could be either, or both. But if one got magnetized by something, like an unshielded speaker, it is likely they both did.
 
best of luck. You might need a stronger degausser. HOw close are the speakers to the top of the monitor and are they shielded or some aftermarket car type speakers? If theyre aftermarket mabye the magnet is just too damn strong.

I can tell you from personal experience it totally blows trying to unmagnitize metal stuff around a monitor. I had a all metal 8liner bartop machine once that despite my best efforts, i could never get the damn thing properly degaussed/demagnatized
 
the speakers are far away as it is a mirrored cabinet. I haven't looked at them to see if they are aftermarket or anything. I will check it out.

I will degauss it every day until the guy picks it up and hopefully he has a deagussing coil.
