I need the complete schematics of LCD Monitors to be able to mend them.


Answer:
Try the LCD monitor repair site. It's a full-resource library with manuals, circuit board diagrams, electronic schematics and troubleshooting tips in one place. It's a great self-help site for hardware & electronics fans.

Answer:
Usually, it's just a matter of replacing either the 1 - 2 mm diameter fluorescent bulb, or the high voltage inverter.

Most bulbs can be ordered on digikey for $16. No schematic needed.

Measuring an inverter's output is challenging without a highvoltage, high frequency probe.
