My hisense 55" tv model number 55K20DG closed caption won't turn off

SOURCE: Hisense Remote

Use the "auto search" method to program the remote and it found a code on its own and get your tv unlocked. Try using 0478 code

SOURCE: hisense tv

Try this code 142, inform us for any updates.....

i know this may sound silly but check the batteries. now if you allready changed them and your still having the same problem check the ir signal on the remote. now all you have to do is take any camera( camera phones work just as good) hold it to the ir sender on the remote press any button on the remote and look through the view finder on the camera. you should now see a light go off on the remote through the camera. if you dont see a light then you have yourself a broken remote. if you do then its possible its the tv ir reciever. and may need to be serviced. but hoping its the remote you can always get a replacment remote for cheep.

Hello

Press the LOCK button to lock or unlock the TV.

When the TV is locked, the screen will turn to blue background, and nothing can be viewed unless you press
LOCK again to unlock it.
OK
[Sometimes you may need to press the LOCK button more than 5 seconds contnously to unlock the TV]
OK.

Hello, it sounds like you have a short in the power supply, this is very common and shouldnt be too expensive to repair. Get a few quotes and pick the best. Approximately $150- $250 depending on what the fault is. By the way, its not usually the screen. If they tell you it is, get a second and third opinion. I hope I have helped.
