Re: 2 inch band across the bottom of screen
Downloading programs would not cause the type of problem you're having. It should be a hardware issue only.
1.The bottom area of your screen is close to a small curcuit panel behind the bottom plastic border of the screen frame. This little panel/bar is called the Screen Inverter. If its connection plug has loosened it could be the culprit.
2. The Display Cable behind the screen panel has become partially unplugged or damaged in some way at the top of the screen, or, it has looseened at its plug connector just underneath the back edge of the power strip panel/keybaord area so that pressure applied to the bottom of the screen frame makes it connect correctly.
3. The Screen Panel itself is failing.
These are the 3 areas I'd say you should have a laptop repair tech look at locally in your area.

if that 2 band according to you from top to bottom,it has a defective vertical stage.if this two band appears one on top and one at the bottom,it`s on vertical stage.leaky capacitors,resistance changed or resistor devalued ang ic`s, are too weak to amplify a signal to make the screen complete....
Sounds like the LCD has some damaged crystals in it. Try connecting the netbook to an external pc monitor using a VGA cable. Hold the Fn key and hit the F8 or F7 key until the display shows on the external monitor. This will determine if it's a driver/settings or display issue. If the display is fine on the external monitor, the LCD display on the netbook is the problem. Good luck!
Fixed mine, myself! Black 3 inch vertical band (stripe) appeared after a cros country move on our PC-T50G10. Occasionally we would see white band with multicolored pixel width stripes. Took the risk of taking off the back to see if I could see anything. Found places on sides and bottoms where plastic like 2" flat cables could be seen. Guesstimated where the band was and found that I could flip down a black cover on one end of the cable. Tried to pull it, gently. Mistake. Realized it wouldn't one out like computer hard drive cables, so I took out the screws holding the plate on the other end (it's only an inch long). That allowed me remove the cable. Took it out, cleared away dust, put t back and closed the black over. It worked! Put the screws back in, back on and... we are happy (although I do have four extra screws!). Just be gentle.
Ur convergence is dead.U Know how to solders?Must replaced the 2 Convergence ICS and all it resistors.Tries Tv Repair World.com,Tvrepairkits.com for the convergence kit to repair it ur self.The shop will cost u $300 for parts and labors.
You have a convergence problem. Here are some of the most common symptoms.
Screen looks 3D One or more colors can't be adjusted when when using the convergence menu. Screen is bowed in but stationary.
Solution: You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit inlcludes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself. Its an easy fix.
Sounds like a problem in the main power regulator circuit, such as a bad capacitor or regulator IC or transisitor. There are no user serviceable parts inside these sets and every thing is soldered into place. I recomend that you call in a trained service tech to assist you with this repair.
