I have a golden tee 2005 and the screen is very greyish with no color or brightness at all.I went to play it today and the screen is very very dark,i could barely see a image.I did get a number off the back its WG1790179 and on a sticker it sais to replace with a k7500 chassis only.Do have to replace the whole monitor or just the chassis.Also if i could replace just the chassis how do i discharge the monitor.thanks
