    From what I've readso far, it's not the inverter. It's the main board or is there a t-con board on this tv?

    The backlight turns on when started up, but when it would load a picture, the screen is black. That's why it's not the inverter

    I have an UPDATE! SOUND WORKS! I tested the video and audio in's on the side and it does have sound, but no video, so if thats hooked up to the main digital board, does that mean It's the t-con board since the backlight does pop on?

Chances are its the Inverter. However since the audio doesnt work either its also possible that the main board could be the cause. As in most cases audio will still work when an inverter fails. so its about a 50% for each board when the audio doesnt work either. You can get some free assistance yo help troubleshoot which board is at fault from www.tvcircuitboards.com they should also have replacement boards for your model.

My LCD HDTV screen keeps going black.


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
