I had the same problem with my hyundai hf2215 tv. Hold down the DISP button on the remote for at least 30 seconds and the lock comes off and tv returns to normal.

Just like a few of your other readers mentioned, we pushed the button below the AV/TV button for 3 seconds and the screen unlocked. Thanks for everyone's advise, we were ready to throw out the TV.

Press and hold the "Music" button on the remote control until normal function resumes. (The problem in the Logic TV originated by pressing and holding the music button. Repeating this action solves the problem and unlocks the TV.

to unlock the parental control on a Telefunken TV that has a blue screen and a red padlock on the top left hand side, hold down the display button on the remote for 10 seconds and it works

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!!!

Hold down the tv call button on the remote for a few seconds and it should unlock.

it is due to vertical section. in tv there is one control called vertical hold control. scrolling down the screen will be ok if you adjust it . if you are not tech.person call tech for help. as you say that it is 20 years old .

If you push and hold down the display button the lock on the blue sceen will come off.

Try pressing the "F" or function button and hold while pressing the Mute or "M" button at the same time. Good Luck
