Sharp Aquos LED TV Problem

This is a 46 inch Sharp Aquos LED TV. It's been working perfectly for almost 7 years. After I carried it upstairs, the TV does not turn on any more. You see the power and OPC light blink in this pattern. If I push the power button, I do hear the little pop sound from inside the TV as if it's gonna turn on the TV. I could actually tell that the screen weakly flashes (very very faint flash) and goes dark. The model and serial numbers are at the end of the video. I am guessing it is a small issue. Anyone has an idea what might be wrong?

I had the same problem but I got it sorted out. Based on my research, the main board seems to be the most common problem. I ordered one on eBay and replaced it myself now the tv works perfectly.

Update: The issue has been fixed. During the past year, I did quite some online research, but did not find any definite answer about what is wrong. Some suggested a bad power board, so I ordered a power board from Sears Parts Direct after making sure that they take returns. The board didn't help. Returned. Then I bought a main board from ebay and it immediately fixed the problem.

The model number of this Sharp TV in the video is LC-46LE700UN. I am adding this comment for search engines.

Hi, I have a Sharp TV 46 inch that does this same thing, So if someone know how to fix it I would appreciate the help.
I changed already the power supply and nothing happened so I just don't want to keep buying parts unless I know that would fix the problem
