Blinking red light and flashing backlights but TV won't turn on.

When connected to power, the red power light continually blinks and the tv flashes but nothing is displayed. I have already replaced the power supply board and the main logic board but the same problem persists. Any ideas on what I should try next?

Answer this question I have this problem too

Is this a good question?

i plug in my 39" Samsung led tv . red light blinks at the same rate the black lights are flashing like a camera. Will not turn on.

If i unplug the led back lights the Tv will turn on, Sound, if i use a flash light i have a dark picture.. Then if i plug in the led back lights in the tv turns off.

What is my fix? bad led? bad power source?

@inktank when you say "tv flashes" and you mean the screen then it could be an issue with the LED array. Post some images of all of the boards on your TV and post those with your question. Use this guide Adding images to an existing question for that. It will allow us to see what you see.
