Help with a Sony X950

My Sony XBR75X950H TV went out a few weeks ago. Issue was it would begin the start up process but after about 10 seconds it would shut off. Diagnostics output code was 4 red blinking lights.
I have since performed a hard reset and replaced the power board. The first start up with the new power board lasted about 30-40 seconds. Long enough for me to go through some of the first time set up options before it shut down. Another 4 red light code.
I now want to try bypassing the backlight error before replacing all the LED strips. I have found the BLL_ERR wire on the power board but not sure what to do since it goes to the main board and doesn’t go straight to the LED controller.
Any help would be appreciated. I’ve had no luck finding circuit diagrams for this TV online.

I decided to replace it and upgrade to a OLED panel. Just in time for the Masters!
$2499 for a 77" LG C3. IMO it was the best deal out there right now as a replacement. Sony is way behind on releasing 2024 models so the A80 is still $3k. So far it is a very nice TV.
But would still appreciate any useful info to bypass the BLL error and see if that will get the x950 working again.
