Sharp LC 80C6500U 1 long 1 short blink

[Rotorcraft230]

Hello all, I have been here from time to time and now I'm back for some assistance.
So I have the TV above and its doing the one long and one short "V" blinking. I did the reset on the controls on the side of the TV and while holding down the volume - and the input button, then plugging in the TV the "V" light is solid, then very briefly I see the backlight flash, then the "V" goes back to the 1 long and 1 short blinking. I just want to make sure its the backlights before I get the parts to fix it. Is there anything else I can do to confirm its the lights.

thanks everyone
Mark

one other thing I noticed when doing this procedure is there is a quick LED light blink on the mother board
