There was a power surge at home from "direct" (no sound delay !!!) lightning strike. Popped a 15 amp breaker for ceiling lights (old knob and tube wiring - perfect antenna?) "Fried" garage door opener buttons and remote, KVM switch, Magic Jack, and a ceiling fan motor.
And my 55" 6 year old Hisense Black Friday Walmart TV.
There is no Red standby LED.
I was wondering how to "jumper" the board on to test voltages thinking the STB pin would be one of the pins.
However, I decided to measure voltages at all 10 pins just so see there was something there to power the standby switch. What I found was something I cannot explain: Voltages with no power connection to board. Now I was working under 4 compact fluorescent light bulbs but that is a reach.
Maybe this is telling me the board is fried?
I have the board pinouts and the voltages are (line cord unplugged) / (line cord plugged to outlet) which is beyond my pay grade. Tried 2 different multi meters.
