I have an l.c.d t.v. and the pic went black and the vol. is out but the power light is still on and it blinks 15 times


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.

My screen is totally black.


If you still get sound, then the problem can be in the backlight inverter board or in the power supply that supplys the power to the inverter board. Look at those two places.

Insignia NS-LCD37-09 turns on but no image


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.
