I need help. I have a INSIGNIA NS-L47Q09-10A with both no sound or picture. I get the light on the front to light up red when plugged in. The light will change to blue when i press the power button. No flash or flicker on screen. No imagine at all when turn off the room lights and check the screen.
I have already replaced the power supply board. It was not producing 12 or 24 volts. The new power works. But I'm still not getting any picture or sound. The closest manual for this tv I found was one for the NS-LCD47HD-09 tv. I also unplugged the T-connector board to see if the backlight would come on but nothing at all.
