I cant to program my cable channels with my univ remot sony tv

Most TVs have manual buttons on them for changing channels. My Sony TV has the buttons on the top of the TV screen.

Try after amke a factory reset to your tV. Normally, aits remote control is needed to make it channel-4.

I assume you have analog cable TV service and no cable box. Press MENU button on your TV remote. Go over to CHANNEL SETUP. There are four arrow buttons and a button in the middle of the arrow buttons on the TV remote control. Use these arrow buttons to go up, down, left and right. Use the button in the center to select. TV On-screen menu has Video, then Audio, then Channel Setup.

Cable can be set to ON or OFF, you want to set it ON to get cable channels.
Go down to AUTO PROGRAM and select it, press button in the center of arrow keys.
A short delay while available channels are searched so be patient. After Auto Program finishes, press MENU to exit. You can perform Auto Program whenever required.

You can also add or skip channels manually. You will discover more options in the TVs menus.

Did you attempt to program the remote with the tv? Is it a universal remote? If so, most remotes come with a list of codes to try with most tv's. Does the volume work? Can you type in a channel direct... pressing 5 for example? If those work but not the up/down channel, the remotes faulty. Or is it set to tv or cable?

pls autoprogram or add manually the channel lost.

Try this: Press and hold the TV Power button and the Dirctv/TIVO button at the same time. Hold both buttons down for about 4 seconds or until remote light stays red. Then press the channel up button until the tv turns off. You may press the button over 100 times. You need to go slow. When the TV turns off press the enter button (or select button).

Go to the Menu setting, and do a auto channel scan, it will automatically program it to NOT skip 3.

Use the code for the sylvania tv. It worked for me!
