I have an insignia ns-lcd22-09 TV. It turns on for about a second and the video disappears. The audio still works. There is no backlight. The flashlight test does show video. I replaced the inverter/power supply but that did not fix it. Any ideas.
Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

If your TV is less then a year old, still under manufacturers warranty. If not under warranty the defective parts could be the power supply or the back light inverter board. Both boards can be replace easily.
The way to know if you have a defective backlight inverter is by shinning a light from a flash light near the screen with the TV on and check in a 45 degrees angle if you have a dark video in the background, if the video is present then you have a backlight board failure. If no video, then is a power supply failure.
I have both boards if you want to buy them.
Let me know if you require further assistance.
