I have a 3 yr Dell UltraSharp 1905FP LCD monitor. Recently, when I turn it on, the power on green light would blink continuously for about 1 minute with no picture before the light become steady green and have picture (everything working).

Thanks.

I have a set of stereo computer speakers, Altec Lansing, Model #BX1121 ''Powered Audio System'' that has a subwoofer and a left and right speaker.
