Monitor flickers with lines across screen


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.

Signal degradation across vertical section of


This appears to be a common complaint on LCD monitors. Some LCD screens have control issues.
An LCD screen is the panel and a bunch of Line control chips wrapped around the outer edge. A problem with one line top to bottom or left to right is almost ALWAYS the LCD panel itself.
A problem with a fixed band (The band is in the same place at any resolution) is often the LCD but might be the signal driver chip (A large plastic pack with about 100+ leads). A person with a VERY small soldering iron might be able to resolder it, but they MUST know what they are doing. (board must be heated, lead free solder, eye like an eagle...)
If the band moves around or changes width, it is the signal chip or the power supply to it from the power board.
It can be software if there is a firmware upgrade. This takes a shop.

Flickering monitor


Flickering screen display

Flickering on the screen can be caused by defective hardware in the computer or by improperly installed software, but it can also be caused by interference from external devices. The following examples describe situations in which your screen could start flickering:
  • Screen starts flickering because of interference caused by devices which generate magnetic fields, for instance:
    • a TV set
    • a laser printer
    • another monitor
    • fluorescent lights
    • hidden power lines
  • Apart from interference, an incorrect setting in your system CMOS setup can also cause flickering. On some systems it is possible to distinguish between interlaced and non-interlaced monitors. The setup of your system should always be colour non-interlaced.
  • Proximity to the monitor of fans, air-conditioning units or other devices with rotating motors.
  • The number of devices using power from the same electrical line. Are you overloading the plug?
  • Monitor placed on an unstable surface.
  • Improper video drivers, this is a software problem, see section B
  • An improperly configured or a defective video card.
