Have supersonic 3.5 inch tv it does not find channels what do I do

That's because there is no signal :>D

Unless you are using an outdoor aerial on the roof and the signal via a aerial cable, your signal is not provided by 'Channel Scan'. In most homes, your television comes from a Cable Box or a Satellite box. The signal from those is fed to the television via an HDMI cable. On your remote, find the Source Button and scroll though the HDMI socket inputs.

Many universal remotes have a code database that you can use to access at least the basic tv functions. I'm assuming you are asking how to program a universal remote when you do not have the original remote. If you are asking how to program stations via buttons on the TV, there is probably a menu button to get in the main menu, then use the channel up/down and volume up/down buttons to navigate the menu.

Return if under warranty?

Hello
Four digit universal remote code for Supersonic TV/DVD combo is:
0944
Direct Code Entry

1. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
2. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks, then stays lit.
3. Enter the 4 digit code from the code tables. Note: after a valid code entry, the red indicator turns off. For an invalid code, the red indicator flashes.
4. With your device on, press CHANNEL UP. If the device responds, no further programming is required. Note: If some buttons do not operate your device, try one of the other codes for your brand

Hello Alfredo. turn on the tv and the DVD player. Use the tv remote and push the input key. When you do that you will see a list of choices. One of them is DVD. Click on it. That said, if that doesn't give you a picture from the dvd, go down through the list one item at a time and you will find it. Joe

if supersonic is not listed in the codes section manual of the rca. then you have to program it manually.
