Simple LCD Backlight Fix

Fix any broken LCD backlight with an ordinary light bulb and a dead CRT monitor.

Broken LCD monitors basically come in three categories:
1) Cracked LCD panel, rendering the unit completely worthless
2) Backlight problem
3) Power supply problem

If it’s a backlight or power supply problem, it can be fixed.
Usually, the problem stems from the high voltage inverter circuitry, either bad power transistors, capacitors, or thermal stress on the circuit board leading to broken solder joints.
But fixing these problems can often be a short term solution. The bulbs themselves have a limited lifespan, and the high voltage power supplies are prone to failure.
