B+ line going hi.
probably bad capacitor on hot's collector.
could also be leaky dual diode.
if non of above, look for swollen cap on main board.

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.

Display Collapse


it is repairable but for the cost of parts and labor you would be better of getting a new 22" LCD monitor
for the problem I would suspect the fly-back transformer or power supply

thanks for rating

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!

A thin horizontal line across the screen


I know I have seen thin lines in the past on older CRT monitors, these are usually wires which support the aperture grill. LCD is just a panel so this must be something different. What color is the line? It is probably an error in the scanning process.
