I Havelocked My Remote And Tv Control Panel On My Sharp Aquos Lc-46le810un

The manual tells how to use the remote to return the keyboard to normal, and the keyboard to restore the remote operation, but since you have turned them both off, then it needs a technician to reset the operation to "out-of-the-box" mode. I would give you the directions, but you can harm the set if you move other things, but more important, having these directions on this post will tell others how o enter the service mode. You can call 1-800-BE-SHARP and maybe they will talk you through it, or just point you to the nearest shop to do a factory reset.

This answer came from a forum about a 52" lcd sharp and I used it on a 46" so im sure it will work on your 60"

To get the set to come on in service mode you are be able to factory initialise

 

3. Entering and exiting the adjustment process mode

1) Before entering the adjustment process mode, the AV position RESET in the video adjustment menu.

2) While holding down the "VOL (-)" and "INPUT" keys at a time, plug in the AC cord of the main unit to turn on the power.

The letter "" appears on the screen.

3) Next, hold down the "VOL (-)" and "CH ( down)" keys at a time.

(The "VOL (-)" and "CH (minus )" keys should be pressed and held until the display appears.)

Multiple lines of blue characters appearing on the display indicate that the unit is now in the adjustment process mode.

channel up and down moves the line up and down and volume plus of minus toggles the settings from what I remember

 

You need to factory INITIALISE in menu 2 and ok wait 30 seconds then reboot
