Try to to put-off your lights and see if you have slight illumination on the screen, if it does, its the t-con board. If totally none, you have to change your Inverter board.
Testimonial: "This was helpful. The screen is dark. Should I replace the Master Inverter, Slave Inverter or both?"
If you will ask me its better to change both Master and Slave for sure and if the price is not much.

Disconnect the LVDS Cable that runs from the small signal board to the display panel and apply power,if the screen comes on,the Small signal board (aka Scaler Bd ) is the faulty board. other than that,all that's really left that has gone bad for me is the logic board.

Hello Mendez the problem that your tv set is having is coming from the inverter board this board provides the high voltage for your backlight without the backlight no picture, what i want you to do is go online sometimes this happens go online look for the service manual for your tv set once you find it get it look for the inverter boards location and check the fuse that is on that board sometimes they blow and it will give you this problem if that is your problem you save money and the hassel of taking it anywhere to get it fixed,if it is not the fuse then the inverter board needs to be changed out and that will fix your problem thank you hope this helps.
