White lines and greenish color are showing up of monitor and on pictures

Try clean install display driver.

Hi,
You have to check for dry soldering in the base board of you mointor. The base board is on which is attached to the picture tube neck. In most cases there will be dry soldering in the pins of cathode diver ic in that base board. It will be difficult find out which pin have the dry soldering. Do on thing resolder all the pins of that ic. This ic cotrols the three cathodes of picture tube (red, blue, and geen) is any one did not get the correct drive that color will fail to display. In your case the red cathode is not getting the drive voltage. Thats why it shows only gree and blue. This is a reular complait for crt monitors.
ok
