Title: Monitor electronics question
Post by: durak on October 09, 2004, 05:52:59 am
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)


Later,

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.
