The flyback transformer is normally at the Horizontal section of the monitor's mother board, It sounds that your flyback transformer might be the cause, bright intensive white lines can be fly back defective. . Try changing your flyback cause I encounter a problem similar to this and it works.

HP Deskjet 5650 is printing off-center. The printing field is shifted to the right, so the right margin is non-existent and I lose a bit of the printing. How can I fix it?


I think the horizontal printing starting point can be adjusted by holding down buttons (??) when powering up. Right now my left margin is 3/8 inch too big -- photos have that much white space on left margin with borderless printing. I am trying to figure out the key combination.

Thin red horizontal lines across screen


replace the focus block or try to adjust the screen control on the focus block for red only. this will affect the white balance of the set so adjust it carefully. the focus block is located on the front inside the set. remove the speaker cover then the 4 screws on the front plate. the focus block is 3" x 2" black box with 6 adjustment posts three for focus and three for screen. adjust only the affected screen (R).

How to fix horisontal lines on display ( see the picture)? They stronger when system is restarted and then fading but never disappearing. They always stay the same.


horizontal lines can be caused by either a faulty grapchics card or a faulty monitor. try adjusting the screen refresh rate. if you are using a windows xp system goto

start>control panel>display>settings>advanced>monitor

then adjust the screen refresh rate and see if the horizontal lines disappear. if not, then you probably have a faulty graphics card or monitor.
