OK usually any lock or such thing will be reset by removing the unit from the wall mains supply and leaving disconnected for about 5 -10 mins. This will reset anything that had been done on the remote.
Turn on the TV and grab the remote. In most cases, you will need the original remote to unlock the TV if you aren't sure of the unlock code. If you don't have the original remote, you will need to purchase one.
Look at the screen. If you see a blank screen with a red key on the bottom of the screen, press 'Function' and 'Mute' at the same time. This should unlock the channel. This is an option for people who want the TV to stay locked but, want to be able to bypass the lock to watch a certain show or channel. All other channels will remain locked and the TV will fully lock when it is turned off.
Unlock all of the channels on the TV by entering the factory reset code. There are three main reset codes that TV manufacturers set. These are 0711, 6688 and 3308. Try each one until you find the one that works. This will reset the TV to original factory settings. When you do this, you will loose any information that you have stored in the TV, such as favorite channels, automatic timers and the clock. You will have to go through the full initial set up.
Call the technical support service number in your owner's manual if none of those codes work. A technician can help you troubleshoot the television because the problem may not be the locking control. When you call, make sure that you have the model number and serial number of the TV.
Take your television to a TV repair shop. In some cases, a professional who access to wiring diagrams for your television set may have to rewire certain components in order for the television to unlock. This is usually the case when the TV locks by itself while it is on.
i There. Had the same problem. The Red Lock indicates that it has been Child Locked, this could be done my accidently pressing child lock. On your remote control there is a MUSIC button, to turn off the red child lock PUSH & HOLD the button. The red lock does not go off with a qucik push. You need to Push & Hold The music button for about 10 seconds.

This has to do with your child lock, just reset that and you will be good, use the manuals and links and fixes provided, i am sure you get the idea, now.

Changing TV, model CKT2521. Classic number CH- 10C. Where can I get a replacement remote control?

You should verify in the user's manual of the remote you mean to buy if your TV brand is listed. Bad new is thart models are not listed.
Your TV may appear with several codes
You should feed the code according to the instructions and test the remote.
It is possible that none of thse codes will work; then your only rsourse might be to scan your remote according to provided procedure, until you get some response from the TV.
In worst case, if no code works, you should return the remote to the shop where you bought it and find another one, so maybe buying that remote from some online webstore might not be the best solution

I have a TruFlat RCA model # 27F520T have lost original remote and FPA lock is on how do I unlock without original remote? Dish universal remote not working to unlock tv, it will pull up menu but cannot...

Try this -
  1. Press menu for main menu.

  3. Press "OK" to enter preferences submenu.
  4. Press CH + or CH - to high light "FPA"
  5. Press VOL + or VOL - to turn the FPA on or off.
  6. Press MENU repeatedly to exit.
  7. Back to normal
  • FPA stands for Front Panel Lock. It makes it so kids don't push all the buttons on the front of your TV. The power button on the TV will still work and the remote will still function as normal.

Blue screen says this tv is locked enter your personal code using 10-keypad then press enter to view this tv-my daughter pressed the cable remote & this happened this is the only remote we have&use

What brand is the TV. I would call the manufacturer tech support. If you have the manual the number could be in one of the back pages. If you don't have the manual search the manufacturer online. They usually have a support link with a phone number.
