Re: Sony KDL - 52W4100 powers off after turn on, gives 14 blinks

snme: Interested in your post, as I have a KDL 40W4100 with same symptoms as yours--primarily 1) Click on/SONY lights up, 2) no Backlight, 3) clicks OFF with 14 blink error code.

I'd like to do the same test you did for the Backlight, before purchasing a TCON online.
Would you mind clarifying a bit what steps you took to test the backlight? I am new to this, and would benefit from some additional description of the steps for that test.
Thanks, in advance!
