Tv screen is dark and back lights are blinking. No sound either

My tv will not turn on. No sound or picture. I plug it in and the power light blinks along with the back LED lights. Tv does not respond to remote either. Got a Tcon board and power supply board. Neither fixed the problem.

ANSWERS:

kmcdpine not sure what you mean your back LED lights are blinking. Since you already changed the power board and the T-con board your next candidate would be the main board. Let us know if those lights blink in a pattern or if they just continue to blink. Post some video of what the blinking looks like with your question Use this guide Adding images to an existing question for that. It will allow us to see what you see.
