Default Re: Philips 234e problem

Whats the panel make and model, sometimes you can find some information that way. Or contact the chip maker
That circuit seems to be the VGH boost converter so it likely boosts the voltage to around +15 ~ +20 volts
Did you check the caps around the +12v boost circuit, The panel is supplied with +5 volts so the +12v must be from a boost converter somewhere
