Re: VIZIO V037L FHDTV20A powers up, backlight on, sound works, buttons work, no pict
U37 is the MOSFET that we put the jumper wire between the Source (pin 1& 3) pin and the Drain pin (pin 5~8). The Gate pin (pin2 & 4) of U37 is connected to transistor Q26 pin C (C = Collector).
The Q26 is getting the correct voltage to bias it on (0.6V on the E (Emitter) and B (Base) but the Collector voltage did not go down like it should and stuck at 12V, that means that Q26 is not functioning.
