From your description, you may either have a bad cable to the LCD on your laptop or the LCD screen itself is going bad. I would guess a repair shop may charge $100-200 for the parts and labor, but you'll have to check your local area for price estimates.
Since your computer is nearly 3 years old, you may want to consider purchasing a new computer, especially since they start at $300-500 brand new.
Hmmmm! I would have to say you have a problem with the signal board. I have not repaired this brand or model. This would be the first thing to investigate. It is the board that contains all your antenna and rca jacks. Good Luck and visit your TV tech with this info!
Check the info from this website to see if you are able to fix your TV. You should turn the blue screen control down slightly counterclockwise. If that did not work, then more likely you have a video amplifier IC defective or a blue CRT.
First reduse the G2 voltage for the blue c.r.t,and watch if the unit works for longer period (offcource blue colour will be not present).After reducing G2 voltage to blue c.r.t still behaves the same than c.r.t is faulty and you have to replace.
Pls count the red led blinking when it goes off,incase it goes to std by mode.
you are experiencing one or more of three things
1.the crt itself is damaged
2. the vertical ic on blue crt board is bad
3. the focus block is bad
if you hire a sony authorized technician they should be well aware of this problem.
Sounds like you have a problem with the blue gun in your picture tube or its drive circuit.
You might remove the back cover and gently tap on the neck of the picture tube using a plastic
screwdriver handle while watching the screen in a mirrow. If the picture flashes back on or on and off then the picture tube is the problem.
If this is a projection tv you have three separate tubes : red, green & blue.
you'd need to tap the blut one.Gently!!!!
