Query: Problems with Monitor

I've had Sony Vaio desktop computers in my house since 1999. I bought this one in September 2006 and just six months later the monitor went bad. It was an excellent computer for the six months I had it. (that was in May 2007) Update from September 2007: Sony fixed the previous problem...the inverter was bad, but now the battery doesn't work and there's a yellow vertical line down the right side of the screen. Fortunately I have 2 weeks remaining on the warranty. Normally Sony is an excellent computer; I think I got a bad system...it's forcing me to purchase the extended warrany plan (approximately $400).
