The monitor has heavy horizontal white lines across the screen. The desktop behind the lines shows up in double. The problem would occur occasionally and currently it has this condition all the time with either the VGA or DVI cable. I've tried different cables, computers, video cards and nothing seems to cure the problem. The monitors is 5 years old. What should I do?

Re: Heavy white lines accross the screen
Replace it, it is going bad. I could tell you what would cause this such as bad driver IC etc. but bottom line is its five years old, you got your moneys worth out of it so bite the bullet and get a new one.

solution 1 please replace the horizontal output transistor in near to line output
solution 2 in case you changed the horizontal output when the problem not solved follow this.
monitor line output transformer burned replace them its kept on monitor from mother board to connect thru picture tube. very carefully to change the part because its have a storings voltage capacity in heavy.
solution 3 check the signal cable
screen is going bad which is why its flickering and has the lines across the screen. Theres a board behind the lcd and when that doesn't process the voltage properly it can cause the screen to flicker. White lines across the screen means the screen is going bad. At this point unless your monitor is under warranty, go ahead and replace it.
Disconnect the monitor from the computer and turn the monitor on it will display a diagnostic colorbar are the lines still there. if not they are likely a cable or video card. if they are still there have a tech evaluate the monitor.
Check to see that the monitor cable is correctly installed. Also, make sure you have the most up-to-date drivers installed for your graphics adaptor card(both ATI and Nvidia carry catch-all driver programs to keep you up to date.) Tighten the cable screws of course, to make sure the monitor cable isnt just wiggling in its seating.
