I will be happy to help. 88% of LCD tv problems are with the backlight, the symptoms you described indicate a probable inverter malfunction. Lets do a simple test to check the functionality.

green screen on hdmi is normally a defective hdmi cable. 1st try a different device , like a dvd player. if same problem try dif cable. if it still does not work you have a defective signal pcb otherwise known as a main pcb.

I recently got this tv from somone because of this exact problem. I have found a solution that works for mine. You can check to see if it works for you also. What I did was take of the back cover. 3 screws (1 big one in the center and 2 little ones below it). Next look at the power board. If plugged in and turned on the red light on the power board should be lit up. If so your power board is fine. Next find the component that has 4 switches. I manually turned these on and turned the tv on and it worked! Has been working ever since!

I'm assuming that the cable is connected directly to the tv, not thru a box, otherwise you will need to check the box by plugging it in another tv - if it's the same then the box is dead: call the cable company and tell them to come and replace it.
The tv can turn on when there is a broken component inside it - it shuts down or refuses to start only if the defect is large enough to block or damage the power source and clearly that is not your case.
Do a simple test: disconnect the cable from the tv, plug in a rabbit ear aerial and see if the tv picks something . If it does then it definitely is the cable, not your tv. If nothing is detected then do one more test: connect the same cable in another tv. If that tv shows the image then your tv is indeed defective.
If the menu appears correctly but nothing is detected then the defect is in the tuner - it got fried. It can be replaced on its own but the procedure is complicated and must be done by a pro. So it will cost a lot - it will be cheaper in the end to sell this tv for parts on Craigslist and buy a new one than to repair it.
