I was told that it has a service menu but I have to purchase the service manual in order to figure out how to access it. Color bleeding requires recapping, so if that is what you're experiencing then you might need to invest in that service manual anyway, but if it's just misconverged then you might be able to straighten that out with a yoke

Gaming. You'll have to rotate the yoke; it's a bit off-kilter. Check the menu pages for a screen tilt option. If it's in there just adjust as needed. You could rotate the yoke. I would try the service manual first if that's an option. Especially with flat screen displays, rotating the yoke can cause geometry issues. . 323 27 126 344 156 340 292 150 304
