I came into a number of iMac DV's some have really dark displays like when they start up, it gets brighter as you let them run longer, any ideas what this could be..

A slowly failing CRT.

My old Princeton 17" did the same thing for about a year or two before it died.

its been sitting discharged for over a week.. i pulled the old crt tonight and figured as long as I had it this far apart i might as well completely clean it.. so all of the case plastics are drying nicely.. this thing smelled so bad. I dont think the PAV board is bad because it powers on just the display is super dark, gets brighter after a bit
