Hisense LED 55A6G… it’s only a couple years old and suddenly wouldn’t turn on one day according to the previous owner.
I’ve done the basic troubleshooting of powering it off, holding the power button then turning it back on, etc. The red power button light flashes two times long, then a very quick two times and goes solid red again.
Capacitors that I can see look good.
Power cord has continuity.
I don’t see any panel lights at all.
Flashlight test, I can’t see if it’s trying to show a picture or not.
TCon board makes a brief buzzing sound when power lights flash two long times.
What’s the next step in troubleshooting?
I’m a computer guy, have done a few electronics projects and repairs, etc, but I’m pretty new to TVs. YouTube is a dead end at this point or I’m looking in the wrong places.
TIA
