Konami 4P Cabs: Is Monitor Shelf Reinforcement Necessary?

<< < (2/6) > >>

It isn't nearly as dangerous as you think it is. People stress the dangers because it is theoretically possible to recieve a lethal charge from the picture tube of a TV that isn't plugged in. Note the word "theoretically"? I don't know of any cases of this actually happening, ever.

I took the full high voltage from a RUNNING vector monitor a few weeks ago. I didn't even get a headache afterwards.

All modern monitors have auto discharge circuits. These circuits USUALLY work. Most monitors I discharge do so silently because they have nothing to discharge in the first place. The only reason you even discharge is because the auto discharge circuits might be bad.

Secondly, the anode cap doesn't just fall off, it would be bad news if it did, but it would be the exact same bad news that would happen if the anode cap fell off a tv set that was inside the case. It would still be a freaking lightining bolt and the monitor would be ruined and probably anything hooked up to it.

Matter of fact not only does the anode cap not just fall off, it is usually quite a ---smurfette--- to get off in the first place, especially if you don't know the right motion to use.

So as far as the anode cap goes you pretty much have to make a DECISION to rip that sucker off and stick your hand in there. It doesn't happen on accident. My incident was with a vector monitor, which is a completely different beast (on a Vectorbeam monitor there is a spring which goes across the back of the tube, this is ground for the tube. I had one with that unhooked, and powered on, managed to touch both the back of the tube AND the frame at the same time, so the tube (which wasn't powering up because it had no ground) was able to briefly power up by going to ground through my body. Until I yelled monkey klaw and jumped back.

Frankly you are more likely to mess up your AC wiring and cause a fire than you are to get hurt by a monitor when you have read about monitor safety. I basically all comes down to two things.

Don't rip the anode cap off and stick your finger inside.

Know HOW to discharge, and WHEN you should do so. (You only discharge if you have to remove the anode cap).

I know that this is a little off subject, but...... How big is a 25" or 27" TV with the case removed?
I have a 2 player super off road that originally had a 19" monitor, and I was thinking about trying to stuff a 25" in there, but when I measure outside the case it is not even close. And I don't want to take the case off a perfectly good tv if it is not going to fit anyway.
Thanks, Patrick

A 25" tube will fit in MOST cabinets. The problem often isn't going to be width, it is going to be depth or height. Few games are narrower than 23.5" and a 25" tube isn't that wide.

Classic examples of the fact that most cabinets will take a 25" tube.

The old rare 25" Galaxians.

Many Defender protos had 25" monitors in the same cabinet that Defender ended up shipping in.

Star Wars cockpit had a 25" monitor and that game is the exact same width as the upright.

Dedicated Neo Geo units were usually 25", but they came in classic style cabinets that were 24" wide.

I don't know the exact width of a 25" tube off hand, but I know from personal experience that a 25" tube will fitthe width in a standard cab and a 27" one wont.

Thanks... That is what I am not sure about. The off road I have is not standard.  I think the width will be fine even if I leave the case on. The monitor is mounted at a downward angleand the height is going to be tight. Depth might be ok, because I can always leve the back off. So.... if anyone has an open 25"tv and can measure the height, I would be greatful.
Thanks, Patrick

paigeoliver:
You can measure height without taking the case off. Measure the height of the visible tube and add one inch (in many cases you don't even need to add the inch as a lot of monitors have their full height as visible tube, but some overlap the bezel up to a half inch, so add an inch to be safe).
