I have Philips 105E 15'' monitor connected to my pc. Since last couple of days it developed a fault. When I start monitor, white part of the screen becomes purple and this color also remains overall dominent for 15-20 minutes and then monitor settles down to normal function. I am using XP service pack 2 .Fault lies with monitor because other monitors work ok with my pc .Please help me out to solve this problem.
Thanks- Omar
