I have a Sharp TV model LC-32SB24U. I cannot access the menu screen because I lost the remote control. Is there another way I can change channels without a remote?

The Sharp LC-32SB24U has menu, input, volume up/down and channel up/down buttons on the top of the TV. When you access the Menu using the buttons on the TV, the Input button is the same as the Enter key. The volume up/down buttons map to the left and right arrows. The channel up/down buttons remain up and down. The Menu button is the closest to the power button (on the right). The volume buttons are the ones on the left.

Make sure that the input is set to TV to change channels. Then you need to program the available channels, access the Menu and navigate to Setup (left/right arrows). Press Input to enter this sub-menu. Then use the Up/Down arrows to select CH Setup. Press Input again to enter. Now you can set the channel source and let the TV scan for channels that have a strong enough OTA signal or are unencrypted cable channels. These are the top two options in the Channel Setup menu. The details are available in the manual which is available here: . For OTA channels, you may need to check the signal strength under the Antenna Setup - Digital option in this Setup menu. OTA Digital signals will not be tuned in if the signal strength is low. It's an all-or-none tuning; amplifiers and external antennas may help. See for details of transmitters and the recommended antenna for your area. (Warning: damaged amplifiers can become filters and block the signal on some channels. Replace the amplifier if it is damaged.)

If you look to replace your original remote with a universal remote, you'll need one that was programmed more than 6 months after the TV was released. That may be 12/2005 based on the manual copyright date. Look for a remote that has a Menu and Input or Source button and check all of the codes to find one that matches all of the features on your original remote. Amazon has an OEM remote for the LC-32SB24U; also has a replacement remote available that has been programmed for the TV. (On, search for the LC32SB24U.)

I hope this helps.

ILO LCD Color HDTV does not change channels / volumn...just turns on/off

The symptoms your TV is experiencing is due to a power supply that is not longer providing the 5 volts properly to the circuitry.
It seems to be a common failure on these TV sets.

Original remote lost. have universal remote. cannot program TV

On the right hand side of this television there are panel buttons. It appears that your son in law knocked the tv out of the correct input. Press the input button in order to cycle through the 5 inputs. Typically pressing the input button on the side panel of a television and pressing it again and again and again will make it change inputs. Universally the buttons on the tv panel function as follows: Channel up moves the cursor up. Channel down moves the cursor down. Volume + moves the cursor right. Volume - moves the cursor left.
Hope this helps

I need to re tune my samsung tv but have no remote any ideas?

you can always use the button on your Tv itself.

ie menu = Menu
Channel up/down = take you up and down
volume = goes left and right.

follow these steps

channel down button to CHANNEL
press the volume button along
channel down button to AUTO STORE
press the volume button to Start the scan.

right now you have your telly tuned in. What you could do it get an old sky remote off a friend/ neighbour. or buy from argos etc ( a lot cheaper then getting a replacement samsung one)

press the following buttons on the sky remote to program it to work with your samsung tv.


try the volume if this works press SELECT to save this code if it doesnt press Tv then try the volume again. repeat this step until the volume works your telly. once it doest dont forget to press the SELECT button to save.

Now you will be able to change your volume use the number keys. if you also press the HELP button on the sky remote this will also change your AV / SOURCE I hope this post helps you out. When it does please leave a thumbs up for me Please

Mintex 37 inch wide screen. remote is working however cannot change channel, input source or volum. only turns tv off. The buttone on tv doesnot work connot change input source or volume

Check if the remote is in TV position, that is, because most of the remote controllers have the feature that you can program them for use with another devices. Make shure that one button that says "TV" in pressed and released once before you try to change any function on the TV.
