that is Always possible - you inspected and reseated them of course?<br />
there is still a slight chance it is the GPU (motherboard), namely the output to the LCD
</div>


<div>
Inspected them visually yes and of course reseated ram and all cables, It is like It am missing a color stream for lack of a better term ie I have red and yellow but no blue so screen looks pink.

<div>
yes )- it can be a bad contact in the cables or connector, so reseat them at least for testing<br />
inspect them also visually &nbsp;-could be a broken wire

A monitor or a display is an electronic visual display for computers, usually comprised of the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors used a cathode ray tube (CRT) about as deep as the screen size. They are connected to the computer via VGA, DVI, DisplayPort, Thunderbolt, LVDS or other proprietary connectors and signals.
