Hi
I was working on my old LCD TV ccfl power supply. Incidentally the TV was repaired by a non authorized TV repaier technician and now was problem associted with CCFL gate driver, I traced the circuit diagram for isolated gate driver for the MOSFET to be similar to the image attached. however I am unable to read the components value from the board as they were damaged. Can anyonw help me analyse this circuit from texas instrument website so a to calculate rough or approximate values for this gate driver. FYI the TV was a toshiba 40BP20 serries and I don't have service manual or schematic of the exact circuit. The power supply has a part number PSIV201141A V71A00025300
