Lock on insignia tv

Hello
Specify your TVs model number. I've to know the model number of your Insigina TV, to give you the method to get it unloked. Send me its model number, which you can see at its back cover label. Send it to me please. OK.

Go to menu and look for lock function and turn off. blue screen. tv is muting video bucause it is not getting any input signal .

just hold down the display button for a few seconds

try this with the tv off simultaneously press and hold volume minus on the tv's front panel and clear on the remote control for 5 seconds then enter a new password good luck

Somehow in handling the remote control I pushed a button or combination of buttons and now have a blue screen with a lock symbol in red in the top left hand corner. I've tried turning the tv off, and unplugging it, as well as a combination of buttons on the remote, but it still is there.
What do I need to do to remove the lock?

I dont have a clue what happened...
The screen is blue and has a little red lock on the upper left hand side...
remote only works to turn it on...no other buttons work.
Help please!!!

The Tv's Child Lock has been activated...
Hold down the F button and press the MUTE button to unlock.
You can only remove the child lock using the remote.

worked just fine for me! thanks!!! 'function' key is in the top left hand corner

my tv is locked & the screen is blue . how do you unlock it ?

the exact same thing JUST happened to us, my daughter unknowingly pushed a button, or a combo of buttons on the remote, we got the blue screen with the lock in the left hand corner, tried ALL of the above (we have the same tv, insigna, only 2 yrs old), I typed the problem in on the net and got the solution, pressing the display button worked!!! Thank U who ever knew this!!!
