1 Need help diagnosing boot up issue
Greetings everyone. I'm looking for some diagnostic help with a TV I have.
It's an Hisense 65r6e3 and it currently does not power on, but it does have a standby light. The light flashes one long, one short and then one long and repeat. That being said, I have gained access to the control modules and measure voltage at the power cord, and it's 65v, I assume that's fine with it being off. I have measured voltage at one pin to the next of the fuse and have same on both sides. Visually both the power board and the other main board, idk what its called, look fine with no signs of burns, broken solder joints or damage. All of that being said, I understand that there are test points along the boards but other than the obvious 3v3 and GND, I don't know what any of the acronyms mean and don't know what sort of values I'm looking for. I could also say that I've checked every ground for a short and they're all okay.
So, what I'm hoping for is to get a better understanding of how to diagnose this issue.
Please and thank you!
Attached are pictures of the TV model and the boards.
Esta é uma boa pergunta?

Harrison Becraft what “ control modules” and exactly where did you measure “voltage at the power cord, and it's 65v”. You should not have 65v on the power cord. There should be household voltage. So if you are in a country that has 110/120v that is what you should have on the cord. Post some picture of where and how you checked. Also post pictures of your boards that look straight at the board. Artistically angled pictures are not conducive to that :-)

You got it, thanks I will.
I was thinking it was suppose to be 120v, but convinced myself otherwise because I tried two different cables and multiple outlets. All of which are the same and I'm literally checking it at the terminals on plug at the power board.
