Chosen Solution
TV turns on, but no visible image on screen. When I do the flashlight test, I can see the menu and move through it. Also, audio, HDMI pass through, ARC, networking/streaming all are working fine so the main board appears to be OK. I am thinking one of the 2 LED driver boards are shot or possibly the power supply board is faulty? Has anyone seen the same situation before? Thanks in advance! HW
Problem solved and TV is now working perfectly. Removed rear panel. Removed power board. Visually inspected components and found a blown capacitor on at C9805. Replaced it with a 100uf 1KV 10% capacitor like TDK part number CK45-R3AD101K-VRA that cost me 0.38$. My suggestion would be to always start with the power board, inspect and test it then work from there.
