Samsung LE32E420E2W Troubleshooting Assistance

Hi people!

I've been trying to troubleshoot an LCD TV which shows a black screen. Backlight turns on, but the screen remains black, menus are not showing.
I have measured the power supply board output:

1 B 13V: 12.70V
2 P_DIM: 4.83V
3 B 13V: 12.70V
4 NC: 0
5 B 13V: 12.70V
6 BLV_ON: 4.07V
7 B 13V: 12.70V
8 GND
9 GND
10 GND
11 B 5V: 5.27V
12 A 5V: 5.25V
13 B 5V: 5.27V
14 P5_ON: 3.11V

and also the ribbon cable of the T-CON board:

0: 0V
1: 3.23V
2: 3.25V
3: 0V
4: 1.36V
5: 1.03V
6: 0V
7: 1.34
8: 1V
9: 0V
10: 1.32V
11: 1.06V
12: 0V
13: 1.16V
14: 1.21
15: 0
16: 1.37
17: 1V
18: 0V
19: 0V
20: 0V
21: 0V
22: 0V
23: 0V
24: 0V
25: 13V
25: 13V
26: 13V
27: 13V
28: 13V

The output voltages of the PSU looks ok but I am not sure if the BLV_ON voltage is too low(also not sure about the expected voltage). Then, I'd like to get some expert opinion of the panel ribbon cable, does these voltage outputs make sense/look ok? Any ideas of what I should be checking next on the T-CON board? Or should I just buy a used T-CON board for replacement?

Thanks for your help in advance.

I would try a new t-con. Or post good picture of t-con.

da quick check of t-con fuse, neg probe on metal chassis, pos probe on each end, see if its around 12 volts each side.
