Green screen on Toshiba 34N9UXE

It sounds that the LVDS cable; the cable that connects to its T'Con board to panel have loose contact with its edge connectors. Re-set it once and check. For more information go to http://electronicshelponline.blogspot.com/

These blinks are fault indications, and are called blinking codes. From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. If you're sound in electronics, this will make the repair easy. If you wish to get more details about these blinking codes, check this link. Blinking codes to many brand TVs are described in detail. http://electronicshelponline.blogspot.com/

I have the same exact problem...for a few weeks the TV would turn off and the red power light would blink. Then the other day I started having exactly the problem you describe...green screen for a few seconds and then total shutdown.

Here is something that may help from the toshiba.com website under your model number television. Q. Why are people on my screen green?

If the problem is not the connections, try adjusting the tint on your television. A high tint setting will usually create a green
image on the screen where as a low tint will create a more red hue. In order to access your television's tint:
1. Press the “MENU” button on your remote control and use the LEFT or RIGHT arrow keys and select the
VIDEO menu.
2. Then use the UP and DOWN arrow keys to highlight PICTURE SETTINGS and press the "ENTER" button on
your remote.
3. Next use the UP and DOWN arrow keys to highlight TINT then use the LEFT or RIGHT arrow keys to adjust the
TINT. If the picture is too green the tint will need to be lowered.
4. Once you have adjusted the tint to your liking, use the DOWN arrow key to highlight DONE and press ENTER. The toshiba customer service telephone number is : 1-800-631-3811. I hope this helps you with your problem.

Some newer sets appear that way when there is NO signal to the set. That and my Sony looks like that when the bulb is burned out.
