Monitor electronics question

[durak]

When I first installed and setup my monitor, it would always scroll slowly on some of the boot up screens, but stop once in windows. I think it was something related to heat, since after running it for a while and restarting the scrolling would not happen. -> Only on a "cold start" the scrolling happened.
But now after having used the thing for a few weeks, the scrolling never happens anymore.

Why I am concerned of this is that the monitor is running on a too high voltage and has a case on it, so maybe these are symptoms of too high temperature, caps drying or something? Obviously there has been some change in the monitor, and only in less than a month of running it.

I don't know if it matters, but the monitor is NOS, never been used but certainly at least 7-10 years old, maybe even up to 20. Picture is perfect.
It is a japanese one meant to be run at 100V, but it runs at ~115V at the moment. I found a guy who worked in the company that imported and cased these, and he said they never had any 100V isolation transformers so that shouldn't be a problem. He said some monitors had caps drying out because of not sufficient ventilation, but I don't have any idea if my cab is better or worse ventilated than these cabs.

Here's a picture of the casing

To me that case looks like a shipping accessory. Does it slide right off or is it  
mounted?

If you have it in a cab I would run the monitor with that cover removed.

(I've got a 9200 in my cab, and have 2 cooling fans blowing across the chassis and neck board, and 3 fans running for exhaust. It runs cool as a cucumber)

The case is custom made, the company that imported them is a nation wide and has a monopoly on slot gaming in Finland, so they have money to do such things. The monitor was used in poker games and such.
It would be easy to slide off if not for the video and ac connectors, which I don't think can be removed from the case. (without breaking it anyway)
And not that I would want to remove it, the cab is very tight in space and it would be a safety hazard. At most I'd make ventilation holes in it if it is necessary.
