The paperwork that come with the remote should have a list of devices and a number to enter for each. There should also be a method to press button combinations till you find a fit.

It could be a timing board failure

You need a more advanced universal remote, that's all. I had the problem too; my first universal remote had only power, channel, volume and guide. A better remote will be bigger with more buttons and have menu options you can use.

Hello, Tom - If you choose not to purchase a universal remote control to use with your Sylvania TV, you can probably use the buttons along one side of the TV screen to adjust the color and whatever other aspects you wish to adjust. First, you will need to turn the TV on by pressing the Power or On/Off button for the TV. Then you will need to figure out what the other buttons on the side of the TV do. If you have the owner's manual refer to that. Without knowing the model number of your Sylania TV, I cannot find an owner's manual for you and give you the specific directions. If you wish, using the Edit feature, you can add the model number of your Sylvania TV so I or someone else can better help you.

Something may have happened in the DVD unit to take out the main fuse in the power board, start by checking that

Hello... Somewhere in the same menu as the Air/Cable setting should be an option to scan for channels. It might be called Auto-Program, or something similar. The bad news is that: "On June 12, 2009, the Federal Communications Commission (FCC) mandated that all U.S. based television signals must be transmitted digitally." Since your TV was manufactured in 1992, it isn't capable of detecting or displaying digital channels. If you're really fond of the TV, you will need some sort of conversion box. If you can afford to, I'd recommend buying a new TV, and get the extended warranty. I hope this helps!
