TV set is dead

After resetting the Samsung UE37D5000 TV with OK until the led blinks etc I have decided to enter the reserved menu of the TV because my image during playback of movies on HDD suddenly was quite dark and not well defined besides the fact the all the other functions were ok. On the diagnostic it said that " T-con Failure"

I played a bit with the menu and submenu and suddenly the power went off.

Now the TV is dead.

The red LED doesn't display anymore etc.

I made some test. The fuse is okay on the PSU. It seems all the voltages are there. From a visual inspection no capacitor seem bulky.

I tried to disconnect the Logic Board and all back light led's came on. I suspect the T-Con but I am not sure. Any advise? Even because to find the T-Con is quite a challenge.

Kindly advise if you can or if possible some logical tips after all the mess I did and for which I only have to complain to myself.

All the best Rob
