Seems to be a lot of similar issues with these All-in-ones.
Good luck.

my tv control panel is locked.there is only on screen av1.it is not changed.

Unplug the tv for fifteen minutes or so.

Call service provider to see if they can talk her thru a master reset.

The Service UART is used to make internal adjustments or updates to your tv. It is intended to be used by service technicians only.

Since you accidently plugged something into it, it's possible that an internal component has been damaged. Your best option is to call a tv repair shop have have a technician check out your tv.

Hopefully, your tv hasn't been damaged and the tech can get it working again. At the very least, the tech will be able to tell you exactly what's wrong with it and what it will cost to repair it.

Have her take the remote and hit 03. Alot of people think hitting the 3 only will work. Not the case have to hit 0 then 3.

The only way to fix it is wit remote , get your self a universal remote and do manual search until set switched on , then go to menu and turn lock off before it happened again.

I'm not sure what type of TV you are using,, but most all Large Screens have a reset button someplace. You should be able to reset the TV and fix the problem. Its not the remote, making the image appear, but a command from it was misinterpeted. Sometimes turning the set off will work, but most often it needs to be reset.

EXCEPTION... if you are using a cable box. Disconnect it from power, wait 1 minute and then see if the problem exists. If the cable box is on even with the DVD you may still have this issue. Please reset the cable, and if that doesn't work, reset the TV.
Thanks! //D
