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.

SOURCE: 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.

SOURCE: 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.

SOURCE: No picture, no sound, does light the insignia sign. Why?

In about 90% of the time the power supply is defective if the TV fails to power ON.
I repair these power supplies, if you need further assistance write to jah2mil@homtail.com

I have an insignia ns-55d420na16 sound YES, picture NO. i have diagnosed: and have narrowed: to either the backlight inverter board or the led itself. is there a way of knowing which IS the issue?


Shine a flashlight on the screen while the TV is on. If you see movement then the Inverters are gone. If you don't get a dim picture then the T-con board is bad. You can get parts here: TV Parts Universal TV Stands DLP Chips ShopJimmy

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board....

Tv picture will not come on


We need to find out if the power supply is putting out 24vdc for the backlight inverter board and 12~16vdc for sound, look for bad caps with leaking/bulging tops first. If you do have all the voltages then the backlight inverter board may be bad.
