How to Operate a sharp TV without a remote control

If both your front panel and remote control are disabled, the best option would be to perform a factory reset to restore the TV to its original settings.
To reset the Sharp LC-40LE830U to factory settings:

1. Unplug the TV from the power outlet and wait for at least 60 seconds.
2. Press and hold the power button on the TV for 5 seconds while the TV is still unplugged.
3. Plug the TV back in and turn it on using the power button on the TV itself.
4. Once the TV is turned on, press and hold the "input" and "volume down" buttons on the TV simultaneously for 5 seconds.
5. The TV will then enter the service mode menu.
6. Press the "menu" button on the remote control to navigate through the menu and select "option."
7. Select "factory reset" from the options menu and follow the on-screen instructions to complete the reset.

Note: The factory reset will erase all custom settings, including parental controls, picture, and audio settings.

Hi Phil Philips, try disconnecting the TV from the outlet, wait 30 minutes, reconnect it and see if it is corrected
If not, get another Philips remote control, usually all are compatible, remove it from the setup menu and then turn it off from the TV, until you get a new remote control

Hola Phil Philips, prueba desconectar el televisor del toma corriente, esperar 30 minutos, reconectarlo y ver si se corrige
Si no, consiguete otro control remoto Philips, por lo general todos son compatibles, sacalo del menu de configuracion y luego apagalo desde el televisor, hasta que consigas un control remoto nuevo

If you happen to have a mobile phone with IR feature, you can download a remote control app and set it for you TV.

Some TVs has the manual control to menu down right, on frame. Did you check?
Else, only way is to get a GOOD universal remote. The one used for DirecTV has a control of SOURCE.

Check this manual

You don't. A good "universal remote" available from Radio Shack (Phillips) for about $15 will provide access to all TV adjustments. Easy to program for all TV models, VCR's, DVD players, etc. About $35 + S&H for the Sharp remote replacement.

several answers:
1get the original remote control
2get a universal remote control and maybe you can get menu from there.
3get menu on front panel of the tv and search for the option.
4send the tv to autoprogram. Good luck!

The manual can be found near the bottom of the Product page for this TV.

From the manual, pg 11 -

If you misplaced your Remote Control you can still access most settings via the MAIN MENU screen when you press both CH UP (8) and DOWN (9) on the TV set. • Some features of your TV Set will not be accessible without the Remote Control. If you lost your Remote Control, contact a Sharp Authorized Servicer by calling 1-800-BE-SHARP for a replacement.

Let us know if this fixes it for you.

its very easy on the t.v and press on channel up or down on your tv. u will get the screen
