Insignia NS32LCD screen shuts off

My insignia NS-32LCD turns on and runs just fine the first time you turn it on, but the screen goes blank after about five minutes, and won't restart for a while. Unplugging it for a minute or two doesn't fix it, I shined a light on it, and as far as i can tell I think the whole screen is shutting off, not just the backlight, if you let it be for awhile, it will restart and run again for a few minutes, as if it's getting hot and shutting off. If you leave it on, after it shuts off, it won't restart, making me think the problem is in a circuit that is powered all the time, not just the cathode getting hot or something. Lastly, it will shut off whether it is displaying something, or it has a blank ''searching for source'' screen, making me think it isn't a problem with the driver, but again, I don't really know anything, just a farm kid making observations...
Any ideas? Does this sound like anything you've seen before?

Thanks!!!
-Parker

SOURCE: Insignia NS-32LCD Backlight or Inverter bad???

If you've done the flash light test, it could be the inverter board became defective but it could also be that the power supply does not provide the +24VDC to the back light inverter board.
If you could do the +24VDC test using a voltmeter then we can say for sure that the back light inverter board is defective.
Let me know if you need further assistance.

Heat the bridge rectifier with a blow dryer and see it turn right on.

SOURCE: Insignia TV model NS-LCD19. TV shuts off

Unfortunately your TV will need to be serviced. You may take the unit back to the retailer of purchase to arrange for repairs.

SOURCE: I have an insignia NS-32LCD and it will not turn

Capacitors are probably bulged in the power supply. Need replaced, not expensive.

Insignia NS-32LCD...Manufactured 2-07


This set should still be under a manufacturers warranty. This set has a board that is very hard to get. Do not let them tell you to wait, or you will wait and not get the set repaired. You need to call and have them repair or have them replace the set before the warranty runs out. If you do you will have a hunk of junk.. Good Luck

How to remove the back from Insignia NS-32LCD?


I unscrewed all the screws in the back, detached the tv from the base, and was able to get the back off. I ordered a new power supply board and will install it to see if it fixes the problem with the tv (won't turn on, insignia light alternates between red and blue). I didn't notice any problems with "swollen" capacitors, so if the new power board fixes the problem I'll update this website.
