I'm working on this Vizio flatpanel, but am having a bit of trouble with it. What happens is that after the power button is toggled, the white light comes on and just pulses. It never powers up. No backlight, nothing on the screen (after analysis by flashlight).
I opened it up and visually inspected everything. Nothing looks off. The voltages seem okay too. 5Volt Standby is good, Reg 20V & Reg 12V are relatively stable, AC_OFF_DET cycles between 3volts and nothing.
Even in this state, it still responds to the power-off command from the remote.
Any ideas?
