it's likely his tv shows blue for bad signal, so either the signal is getting messed up in the cables, or it's showing a black screen, and your tv is seeing no signal and showing blue, my vcr will show blue if i have a ps2 that show's black screen....umm...
1. does it always show blue screen, or is it occasional along with no eject light??
2. does the ps2 eject, when no eject light (if it eject's i'd assume your ribbon cable may be cracked and causing the eject light problem)
3. do disks spin up even though it doesn't show screen?
4. any idea's on what happened when your ps2 started doing this i.e. droppage, lightning. etc.
EEEEEEWWWWW... girls gots cooties
