Inverter protection | Wear of the LCD lamps. | Transistor q1 is responsible for the protection circuit when the lack of phase in reverse (shorted lamp or inoperative output) or one of the phases is uneven (lamp wear) and a potential direction is generated and q1 is activated, well I put a resistor 10k from the collector of this transistor to ground and the protection circuit stopped activating, when the collector raised the voltage above 1.0vdc the protection was activated, with this resistor the collector remained stable at 0.2vdc, hence the protection circuit was deceived | Edson Caeté |
