Hey, everyone. I apologize for the beginner type question on here, but I just recently bought my first arcade units (A Mortal Kombat II machine and a Neo Geo sans pcb board) and I'm still trying to figure out all the kinks. Please bear with me on this.
I've recently added a new board to the Neo Geo machine and it looks like everything is working fine with the board itself. However, I noticed the brightness on the monitor (A Wells Gardner 25K7193) is slightly dim when it first starts up, with a slight reddish tint on most things, making things look off. Adjusting the brightness and contrast only succeed to make the image look "washed out". I expect some amount of this to be normal, but after about 15-25 minutes, the problem will stop persisting and the image will look like how it should, similar to that of a backlight suddenly turning on. The image will sometimes flicker between the two when it "fixes itself" like this, but it's generally okay from then until the unit is shut off again. Is there something simple that could be causing this? Is it old age (It says it was manufactured in January of 1992)? Or is there something far more sinister at work?
I apologize for not having any pictures of the unit and the problem, but I will get them once I get home from work if needed.
