I have a LED light with two drivers( ballast) each driver has a dimming module connected to it. One of them turns on but stays dim and does not do anything when turning the potentiometer . It lloks like IC1 died but I can't figure out what IC1 is, there are no markings I have checked other one as well. Every other component seems t be ok potentiometer and adjustable resistor work good as well.
There are 4 pins:
1: On/Off — reads 0V when the potentiometer is off and 10.77V when on
2: +12V — reads 11.78V, comes from the LED drivers
3: PWM (0-10V)
4: GND
