Hi,

Well i found some things called R-Bias, G-Bias, B-Bias...turned the
red one as fas is it can go and it does change to red...not as nice as
my RGB monitor though...so not sure if something is on its way out. It
proves the red gun works i suppose. Cheers for the help michael...that
might keep me happy for a bit ;-)
