Hi, I have an iMac G3. The specs are: 600 MHz G3 /Graphite 1 GB RAM 40 GB HDD CD-RW Mac os x tiger 10.4 Here are the 2 problems with the screen/ crt: The problem with the screen is that it's not as good, as it used to be. I have another g3 imac (450 MHz Sage) and my dad pointed out that the sage imac's display is much more sharper then my 600 mhz graphite. And i had a look at at it and my dad was right. Also their are lines going down the sides of my screen (which you can barely notice on the sage imac) is their a way to fix this? Thanks. Also another problem i have with the screen is that I am seeing rainbow affects on the screen. I read online that the anti-glare film/coating is scratched (but thats with different crt monitors eg sony 21" etc) Is their a way to fix that as well? Just today I noticed more and more showing up! (or is it just me!) Any help would be great! Thanks!
