LCD screen inverters The inverter in LCD monitors and laptop screens is used to produce the high voltage necessary to drive the cold cathode fluorescent lamps (CCFL). Due to the stress imposed on these inverters, they are one of the more common parts that fail in LCD monitors and laptops screens. Although we keep our repair charge to a level that makes a repair economical, carriage costs can be high due to the weight of monitors and laptops. Customers who wish to remove their inverter board can send them to us for repair, saving considerably on carriage costs. There are however, several important things that we ask our customers to be aware of before removing their inverter for repair. The common symptoms of a faulty inverter are:
Although the above symptoms are typical
of a faulty inverter, a faulty power supply, CCFL, or A/D board can
produce the same symptoms. Due to the time taken to thoroughly test
inverters that we receive for repair, any inverter that proves not to be
faulty, will be charged the full FPR. It's also possible that an
inverter could have been damaged by a faulty CCFL. If any faulty CCFL
is not replaced before refitting the repaired inverter, in time, the inverter
will fail again.
