@snevets, if your display appears with a green tint then the green LED seems fine.
The absence of red causes the green tint.
When the red LED fails the display has a green tint because of the lack of red color spectrum.
Replacing the red LED on this television is comparable to replacing the CPU on a computer.
This repair took me a little less than 1 hour to complete.
This includes the time I took to document the repairs with photographs.
I have had around 5 users complete this repair using my guide, and no failures!
Good luck!
