Hello Friends...I am having a problem with the colors in my CRT monitor(SAMTRON 56v 15'').The prob is that i am losing some colors.Most of the time i am not getting the red color.I guess it is a problem with the signal cable because when i twist or move the cable,the color that i am losing changes..In some particular position the colors becomes okay..and somewhere the screen goes blank...So can i get a replacement cable somewhere..?..Or can it be repaired..?
