Question about Insignia Televison & Video

1 Answer

I have an insignia tv ns-lcd42hd-09. If I have no backlights and cannot see the menu with a flashlight does it still mean the inverter is bad or is it the t-con or main board.

That brand TV will not display anything on the screen if the backlight is burned out. Depending on how much you paid for it, you might come out better just replacing it that repairing it. The backlight stretches the length of the screen and it only takes one diode to go out to cause the whole TV to go out. If you are a DIY person, know you will be dealing with 50-70 screws. NOT counting the plastic mounting screws for the front and back bezel.

The other kicker is the availability of the actual part. The LED strip used for the backlight WAS a proprietary part and is supposedly available only thru the manufacturer. However, it is possible to replace it with a modified strip from strip LED lighting, a little soldering, and a little bit of know-how. This will void the warranty, but, if it fixes your TV for actual pennies on the dollar, you cut out the middle man by doing the work yourself, you're looking at about $50 for parts.

Hope this helps. http://www.indoffofficefurniture.com/led-retrofit

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

NS-LCD42HD-09 Insignia. The power light is on, but no sound, no picture. TV is 13mths old. Best Buy junk I'm guessing, but as a electrical engineer, I'm determined to fix it myself. I think it's the power...


At least the 5VDC stand by power supply is working, there will be a control signal pin from the mainboard to the power supply board to turn on the rest of the power supplies (24vdc for the back light inverter boards, 12vdc for other circuits). Any bulging caps in the power supply?
