COMMON FAULTS IN MONITORS !

PROBLEM 1: TFT DEAD
  If the TFT is dead then check whether the fuse is damaged.

        1.1 If the fuse is not damaged then you have to check the following components in order :

• Switching Transistor
• Switching IC's
• Filter capacitor
• Primary section resistor open
• Primary section diode short
• Secondary diode short
• Inverter power chip fault
• Invertor on/off control transistor

        1.2 If the fuse is damaged :

•  Then the circuit is open, so change it or repair
