When turned on, the green power light flashes as if everthing is ok but then when it is time for the picture to come up the screen flashes one time, I hear the show for one second then it shuts down. The flashing green light changed to a flashing red light. This happens everytime the unit is powered on.

The flashing green light is likely indicative of a self-test failure, indicating the TV has detected some sort of internal fault. With no picture or sound, one strong suspect is the power supply. Flat-panel TV's have an internal DC power supply that converts the inbound AC current, and when these fail, or are unable to supply a minimum level of power to the set, it can behave as you describe, providing only enough power for the green light to illuminate.
Check the Lamp if no picture, audio may be present. Screen is completely dark. Lamp LED
flashes 2X every 5 seconds, Power LED flashes GREEN for 140 seconds then
flashes RED. Check the ballast if no picture, audio may be present. Screen is completely dark. Lamp LED
flashes 3X every 5 seconds, Power LED flashes GREEN for 140 seconds then
flashes RED.
Try removing the motherboard from the screens and attach the battery the green light should turn on and stay on.
Now attach the lower screen and turn on. If the screen is ok the screen and green light will flash and then turn off. (if the screen doesn't flash the bottom screen is you're problem and will have to be replaced)
If this happens the problem is then you're top screen which you will have to replace.
When the lamp fails in this unit, often the thermal fuse opens. The error code is 6 blinks. To replace this part requires a great deal of deal of disassembly.
i also have the same problem with the flashing green light for a while then a different red light starts blinking on and off around 5 times....and i replaced my burnt bulb with a new one...still no picture.
