Re: screen

First of all , it could be a solder problem try resoldering taking care do not leave any shorts circuits por ahi,may be a shorted coil, you have to test them all,look for a shorted diode esp. in de horizontal area. if any of this things sounds rare, leave it to the repairman!

When i am switching on my pc the picture shrinks and shows a green line.imy warranty period has expired.i want to know if it is a general problem and can it be repaired or it has to be replaced?

it is possible that the monitor has a power crunch as a lower voltage gives out a shrinking picture. also it is possible that the deflection circuit or the vertical circuit, the vertical driver IC or section is faulty.
You can remove power and check for dry soldering, measure the power supply to confirm.

This indicates that your vertical sweep has failed and the auto protection circuit is shutting down the video so you do not permanently burn that line you see into the phosphor coating of the CRT.
At any rate, the vertical sweep circuits need repair before the unit will work again.
Good luck.
