@mike8888 your panel is a LED backlight panel. If your Display actual appears to turn on and off and thus looks like it is blinking, you may have issues with the backlight array. Your TV should have an LD board and once you have your TV apart post some good pictures of your boards etc.. Clarify for us that you get sound etc. or that you at least checked if you maintain a picture during the blinking, by shining a flashlight beam at an angle against the display. Personally I’d check
power board output
LD board
LED backlight array
My number one suspect here are the backlight strips but measure the voltages between main board and LD board etc.

@jayeff possibly a generic message. I've added the SM to my answer for verification [document|6321] Hopefully I’ve read it right :-)
