Dont ever open your monitor and take off the shields. Each and every CRT radiates and those shields are there to protect us from Radiation. If you are operating your monitor w/o those shields, then you are getting exposed to Radiation (i would recommend a Doctor checkup for you) Also, pls tell me who you are so that i can stay about 1 mile away from you
as for the pink tint to your monitor, i had that once and thought my monitor was gone. Just when i was unplugging my monitor, i noticed that 2 of the pins (at the vga connector) were joined together. I separated them and straightened them and it was fine then. Monitor has been running excellent for 6+ years now.
