Hello,
this problem can be fixed by opening the back cover of the television to check for blown fuses, and if found replace with the same current rating and if otherwise the power board supply is bad try websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

How to repair an insignia 37" led tv


The first thing I would try is to disconnect the tv from the power source. Wait five minutes before plugging it back into the wall socket. Turn the tv back on and see if you get a display. Try changing the channel and switching inputs. See if you can get it to display anything at all. You could shine a flashlight at the screen and see if you can make out an image. If you see an image with a flashlight then your backlight is out.

Is your tv less than a year old? If it is less than a year old you are still under the manufacturer's warranty. I would see if Best Buy would honor the manufacturer's warranty in store. If that is not the case they should give you a number to contact Insignia directly.

If your tv is out of warranty, it may be cheaper to replace it. I would do your homework and check the price of a repair vs the price of a new tv.

Insignia 26 inch TV/DVD Combo produces strange odor when on.


You should never have an acrid or burning smell coming from electronics. I'd return the unit, if that is still an option, as it is about to fail.

Insignia? 37 720p Flat Panel LCD HDTV will not


Power-cycle the unit (turn it off and unplug for several minutes). If you're unable to power the unit on successfully, the TV probably requires repairs. In home service can be obtained by calling 1-888-237-8289 in the U.S. or 1-866-237-8289 in Canada.

When i turn on tv screen is bright white instead of blue!!!


This is a problem that should be taken in for service as there could be many problems causing the problem. The power supply could not be supplying voltage to run the video card or you could have a failure in the video card itself. Try calling this number for Insignia Customer service help. 1-877-467-4289. Hope this helps you with your problem.

Insignia lcd 37''powering off and right back on by itself!


Hi Ed,
Since the TV is less then a year old and still under manufacturers warranty, I would suggest to take back to the vendor to get it fix because this LCD behavior is not going to get any better.
The failure on this TV is related to a power supply in most cases if the TV is turning OFF by itself or needs to be unplug to let cooldown and it works afterward.

TV was playing, then the screen turned black.


If the screen is black and you have sound then lightly press and shine a strong flashlight against the screen. If you see an image around the edge of the flashlight, an image is being 'displayed'. The problem is probably in the Inverter/CCFT or the power going to the Inverter.

Insignia LCD HD tv with "No Signal/VGA input"


With the model# and date of manufacture I, or others might be able to help better.
• Generally, Most of the insignia TV's are manufactured by Lucky Electronics and have some amount of problems on the main board. The power supply filter is likely drying out it's capacitors as they use caps that are to close in rating to their actual voltage. IE 25 volt caps in a 24.5 volt circuit.
(We replace them with 35 volt.)
This causes flakey actions. Try unplugging the set for an hour, and try it again. It may work, but for how long? IF it works, you should replace all the caps in the power supply area, about 10. You can be sure that one is bad if it is swelled up, dome shaped on top, or hot.
