NEC MultiSync FE950!

[TOCSYS]

The problem started off with a grey flicker. The screen would just flash grey for about a half a second then go away.(Everything on the screen was grey including the text so nothing was ledgable).I thought it was my videocard so I switched it to my other PC but the problem still existed. Now the flicker has turned into more than a flicker. It stays grey for a few seconds and then flashes away. Sometimes it would stay grey and the only cure for it was to tap my desk table. Now, another problem has come up. I was just surfing the net and all of a sudden my screen had a pink/purle hue and was flickering from that color to the normal operating color. Unlike the grey flicker, however, I could read everything. It was like changing the color settings on my monitor. All of my speakers are shielded and I keep the monitor free of dust. I haven't had it for too long and I'm getting kind of annoyed. Anyone here know if I can fix the problem myself or should I just contact NEC asap?
