My tv is on the fritz, 50ux58B Hitachi. Green diodes come on then off again in the interior of unit, red led blinking afterwards. Have not been able to locate C-707 nor E-994. Any good advise out there?

I have a Samsung TV model QN75Q7FAMFXZA, which has a blinking red light and won't turn on. When I press the power button on the remote, the remote just flashes red for a few seconds and goes away. The Tivo remote will not turn the TV on either, nor will the Apple TV remote. A couple of weeks ago, the TV would start to turn off by itself. This happened a few times but eventually it wouldn't turn back on. The TV is mounted on the wall and when I went to pull the TV out from the bottom to reach behind and unplug it, it suddenly came back on. This worked a couple of times but eventually the TV would not come on anymore. I figured the power cable must be loose so I removed the TV from the wall, set it on the floor and plugged it into a wall outlet but still the same results.

I have read forums and articles of which most point to a bad power board, usually due to a leaking capacitor. I have taken the unit apart and inspected the power board but to me, all the capacitors look fine. The board in the lower middle makes a clicking sound every 1 second or so. It's a very faint sound, not sure if that's normal.

Any suggestions
