Re: Toshiba 42HL196 no power on

I just repaired one of these sets with the same problem. "LED flashes 3 times". I too replaced IC Q820, IC Q850 and IC Q880. As I had found in my research it takes between 15 to 30 seconds for the set to initialize the first time but then the OSD popped up. I applied signal, set the correct input and it was good to go.
