Reparing LCD Monitors – These LCD Monitor Problems Can Be Repaired Cheaply and Easily

As long as the LCD panel itself is not damaged, most LCD monitor problems can be repaired electronically, or through component replacement (like capacitors, transformers or power board fixes)

Even scratches or a star-burst pattern on the screen can be repaired – but broken glass or dark areas on the screen can't be fixed.

In the latter case, screen replacement is the only practical option.

LCD Monitor Panel – Performance Lifespan of a LCD Display Panel

The LCD monitor panel isn't just a slab of glass that lights up when a high frequency electric current passes through it. It has a complicated array of in-built electronics, each of which has its own life span.

One of the main components of the panel, the CCFL backlight lasts up to 20 months (15,000 hrs). In comparison, the LCD glass itself lasts almost 6 years (50,000 hrs)

CCFL tube (cold cathode fluorescent lamp) is the most commonly used backlight in modern-day LCD monitors.
