I have a 19" with a Wei-Ya 2620H chassis that I recently installed in a cocktail. When the monitor is laid down as seen in the Cocktail_Monitor jpg I get an excellent image as seen in DK_Good jpg.

But when I move the cocktail top assy with monitor to put it back into the cocktail body, I can see a bloom start at the bottom right corner and get worse as it move into the cocktail body as seen in the DK_bad jpg.

At first I thought it was ferrous metal. So I removed the CPs, coin door and anything else metal I could find. No difference. I then added the shield to the monitor and plugged in degauss pins on the chassis. No difference.

So it must be the tube right? Something loose inside?

Any advice or suggestions would be appreciated.

Thanks.

I'm no expert, but it looks like it just needs degaussed. It should do it by itself after a few cold start ups or from being on for 20 minutes or so. If not, manual degaussing is an option.
 
That's normal. It just needs to be degaussed. All color monitors do a degauss at poweron, all you have to do is turn the monitor on (from cold, like 1/2 hr of off) in the position you want it in. What you are seeing is the Earth's magnetic field interacting with the CRT.

A manual degausse won't always fix it. Sometimes it has to be corrected over time. Especially if it was around another object with a magnetic field for a long period of time.
 
When I installed a new monitor into my cocktail it did the exact same thing. I bet you turned it on with the cabinet laying open didn't you? lol
No issue. You need to simply close the lid and wait a good 30 minutes or so. I bet you'll find it'll correct itself. Something to do with firing it up on its side jacks up the colors which to this day I still don't understand.

There is a chance you might have to manually degauss it though but I wouldn't bet on it.
 
I just ran into this exact issue. Did it degauss itself? I don't have a degaussing tool and don't really want to buy one right now...
 
I have a similar problem and would love to degausse it, but how do you degausse a monitor in an exidy crossbow cab? The monitor is upsidedown facing backwards?
 
It can be done the same way (but farther away, obviously). or just open the back to access the monitor and do it that way...
 
It seems to make it worse, if you move the game or monitor while it's turned on. Most of the time, you can turn the game off, move it, and then back on without an issue.

In other words; don't move the game while it's turned on !
 
You can cut one off an old tube, and install a switch inline with it. You can only use it for a few seconds though, it'll get really hot, lol.
