My panel is frozen or locked and I have tried to take off the child proof lock but nothing works. I have tried to press the power freeze and the fridge buttons but nothing happens.

I would power it off, wait for 5 minutes and plug it back in.
If the logic board has frozen, that will reset it.

Is it t h e child proof lock? Press CLEAR/OFF button for 3 seconds to see if it unlocks.

Have switched this on?

Child-proof lock
? You can protect the appliance from being tampered by activating the child-proof lock.
? When activated, no change can be made to the programme running.
To activate the child-proof lock:
1 Press the 1st and 2nd additional function buttons for 3 seconds.
2 The "C ON" (child lock is activated) symbol appears on the screen.
Note: the child lock symbol will also be displayed whenever any button is pressed while the
machine is child-locked.
3 The child-proof lock lamp on the programme follow-up indicator will light up when the childproof lock is activated.
To deactivate the child-proof lock:
1 Press the 1st and 2nd additional function buttons for 3 seconds.
2 The "C OFF" (child-proof lock is deactivated) symbol appears on the screen.
3 The child-proof lock lamp on the programme follow-up indicator will go off when the child-proof
lock is deactivated.

It still sounds like the child lock is on since that prevents accidental setting changes on the refrigerator's control panel.The following will NOT work if the child lock function is activated: Freezer Temp Button Fridge Temp Button Power Freeze Button Power Cool Button Ice Type Button Water Button Ice maker Water OR it may be in Cooling Off/Demo Mode. Cooling Off/Demo Mode is a feature used by retailers to display the refrigerator without running the compressor. If your unit is not cooling, and the bars are constantly scrolling up and down the temperature, check your manual for reset advice

The most likely cause is a defective lock actuator.You'll have to pull the door panel to get at it.Unplug the connector,and rig a 12v test light across the two connector pins.Pressing the lock or unlock button should make the light come on(lock or unlock just reverses the polarity).If you get a light,then the actuator is the problem.If not,then trace back towards the lock relay to find the open in the circuit.

Child Lock is activated. Look for a picture of a small child's face on the Facial Panel (usually with picture of a lock) follow the arrows to 2 buttons, press and hold these buttons for 5 - 7 seconds. Child Lock will then deactivate.

Hope this helps

Hi what you can do is to buy a universal remote control for this TV to remove the child lock. You can get that online or on any electronic shops in your area. Once done here is the instructions on how to remove the child lock using remote.
Look at the "Power" indicator light on the front of the television to check if it is blinking. When blinking, the child lock is enabled. You can also check by pressing the "Power" button on the television.
Point the remote control at the television and press one of the buttons on the number keypad. The "Power" indicator light will stop blinking, indicating the child lock is turned off.
Lock the television again by pressing and holding the "Power" button on the remote control until the indicator light starts blinking. It takes approximately three seconds before the light turns on. Thanks

to make sure you do not go through a lot of work for nothing did you make sure that the child proof switch is not activated on the edge of the door when opened?

To turn off the Child Lock
Press and hold ENERGY SAVER DRY for 4 seconds. The
light turns off.

you can try it by pressing the power button and the tv/av  button at the same time, that worked for me ,My tv is about 8 years old
