Hi , I`m Jack
Perhaps I can help you with this problem

Expert:  Jack replied 7 months ago.

What is the tv doing now if anything ?
Is there a light or blinking light at the front , clicking sound from inside when you plug in the power cord or try to turn it on ?

Customer: replied 7 months ago.
nothing. I have it turned off
Expert:  Jack replied 7 months ago.

O.k but is it completely dead or is there some sign of life ?

Customer: replied 7 months ago.
the red light is on on the front of the tv. It goes off when the tv is turned on.
Expert:  Jack replied 7 months ago.

O.k then there is hope

Here is something for you to try ;
Unplug the TV's power cord and hold the power button directly on the tv ,keep holding it for 20 secs or so then let the tv sit unplugged for a couple of minutes before you try it again.

If that does not do it then we are looking at internal problems with the tv.

let me know how that goes

If that doesn`t do it then your local bestbuy`s geek squad will be the ones doing the service on it .

By the look of it the power board has failed .

Here is also a link to insignia where you can get more info ;

It would be a good idea to have you bill of sale but if you paid by credit card then they will have a record of this.
