I just want to let you know, the method of bypass lcd
protection is using for "Testing" purpose only, not to using it as "Repair" lcd display!
For example, an LCD Monitor has backlight shutdown
after 2 seconds. So you need to check their inverter section voltage Vcc is present or not. And then the BL_ON
signal. If both normal and stable, then you need to check the inverter board/section and the ccfl lamps. Using the
ccfl lamp tester to testing ccfl lamps, if all lamps ok, then you should check the inverter section. After checking
all of the inverter components and all are normal, then you can start using this bypass inverter protection method
to find out which components is defective and causing the backlight system (inverter section)
Please DON'T just removed or bypass
the inverter protection and got the display appear normally and then just return it to the customer! It
will cause a BIG problem later on. Maybe the lcd monitor or TV burnt, explode or fire!
Everything MUST SAFETY FIRST!
