I got two Sony KDL-46z4100, same problem: blank screen, then shut off gave 14 blinks.
This is the t-con problem, part number 1-877-777-11, I checked all the fuses, F603 was open for both t-cons. I replaced one of the t-con fuse, TV works for 2 hours and then shut off gave 14 blinks again.
I checked the replaced fuse, not open, the other fuses are fine, looks like something else burnt.
When I measured one of the diode (815B), surprised the resistance is not the same as others (There are 4 the same diodes near by). I thought this is the problem.
I did a research but still not find any datasheet or specs for this 815B diode (R825 marked under 815B).
