How To Repair Common Hardware & Electronic Problems of a LCD Monitor

Common problems that affect a LCD monitor include:
  • Failing backlight bulb
  • Burned capacitors
  • Scratched or cracked panel
  • Dark screen with dim light
  • Non-functional inverter board which cuts off power supply to your monitor screen
If the screen panel is cracked, there isn't much you can do except go for screen replacement. But simple scratches can be fixed for under $10 with a LCD scratch repair kit.

If your monitor has become dim (dark), this is because of a failing backlight or power supply board. You can replace them both with low-cost parts from Ebay.

As long as your LCD panel is not damaged, most hardware & electronic problems can be fixed by repairing / replacing the backlight, inverter or a simple electrolytic capacitor.
