I just got a new guitar (2001 RG 2550, i'll make a new thread when i take some pics

)
It's in very good condition, but there's a dead spot when bending the 15 fret on the high e (not when i hit it, only when i bend it).
Is there anyway to completly solve this? I'm going the to raise the action a bit because it's to low, would this help?
any comments are highly appreciated, because i can still send it back if i want.
Cheers!
