I have a 19" Sylvania

It is over 10 years old so would no longer be supported.

Difficult or impossible----Sony and Mitsubishi have less than 5 common codes but Philips who is Sylvania at last count had over 30 and some units with their name are made by other companies and will each have a different and non Philips codes----the comcast remote does not have that many codes for this purpose.

Check if there are input on the audio connected.

Replace Lcd screen.

3. Press the pound(#) button once.
4. Test the functionality of the TV.

Hello! I hope that you have gotten this resolved, but if not, here are some steps to do so. You can program the remote to the TV first and then use that for this, or you can use the buttons on the TV itself.

Remote to TV Steps:

1. Hold down the clear TV button until all lights light up at the top of the remote
2. Punch in a 3 digit code (provided below)
3. Press the # (POUND) button
4. Try powering the tv on/off, and the volume. If one or more of these functions do not work, start over from step 1 with a different code
527
733
632



Satellite picture back:

If you are at TV1, where the receiver box is located, the tv needs to be on channel 3 or 4.
If you are using a coax cable, the TV needs to be on 3 or 4.
Depending on the cable that is running between the receiver and the tv, the tv may need to be on an input, such as video 1 or 2. If you are at the TV2 location, where there is no receiver, then the tv needs to be on channel 60 or 73.
If you are using an HDMI cable, then the TV will need to be on an HDMI input
If you are using Component cables, your TV will need to be on a component input. (Usually Comp 1 or 2)
If you are using RCA cables, then the TV will need to be on a VIDEO input (Usually Video 1 or 2)
