Flashing LED at bottom is normal power up cycle for Samsung. You'll need to get it opened up for some voltagce checks.

Do you have sound? If you shine a light at the screen, can you see a picture, or the menu (if you push the menu button) Un plug tv, the disconnect the cable between the main board and power supply, plug in tv to see if the backlights come on

Open it up and unplug the wires from the power supply to the mainboard. Plug tv back in and if backlights come on, the mainboard is bad. I have a feeling it is because I have seen this many times on c600 series.

the red light near button on/off bliking 2 times and then a small sound appear "like sound error" and stop blinking again 2 times = small sound error and stop blinking .

i make a second test i disconnect the cable going to the mainboard and i turn on the tv and now the tv back light turn on i suppose the problem is in the mainboard ? but not sur ...

i would make some test measurement but i m not sur about my test ... how to proceed i post to you some picure to help if possible

thanx a lot
