Hi, My 14" CRT monitor (Vintron), which was part of my original machine bought in 1999, is facing a peculiar problem. Actually for the last few days, the screen is not shown in original colour. It is giving greenish, blueish an yellowish tinge. Also it starts flickering when these discolouration are shown. What has become the problem? And how to solve it? This monitor has given me great service for over 6 1/2 years. Waiting for your comments!
