Apex model PF3225, The TV is Locked (blue screen with red key on the bottom left corner). Don't have original remote...please help

Press the "Menu" button on the remote control and use the arrow buttons to scroll down to the "Parental Guide" option, then press the "Enter" button.
Type in the default parental code "6688" if you have not set your own code. If you have set your own code, type it in. If you set your own code and forgot it, override it by using "6688."
Use the arrow keys to switch the parental lock to "OFF." This allows all programs to be viewed no matter the rating. Press the "Exit" button on the remote and start watching all your channels

Wharfedale 21in tv blue screen with the word key in top corner with 3 dashes please help


You have accidentally activated the system lock or parental lock. This usually happens when 2 buttons are pressed on the remote simultaneously.

You will need to enter a PIN number using the numerical keys on your remote. If you have set a PIN number for this TV you will need to enter this. If not, you will need to enter the manufacturer's default PIN number. This is usually a simple combination such as 000, 111, 222, 123, etc,

I can't tell you the exact PIN number without knowing the model number of the TV. Please try the simple number combinations shown above and post back with the model number if you need further assistance. The model number can usually be found on a sticker on the rear of 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.
