Maybe someone can help me with my...TV?

Read the manual? Dunno.

OK, so you were fooled by the digital changeover. Most cable systems will continue to be analog for many years. They are digital on the cable but that is a different system. Until you purchase HD cable, the box still produces an analog signal most often on channel 3 or 4. The "reset" could be a reset for the cable box or the TV. It is clear that you ran the auto channel scan in the second part of your post. It should only find the cable box if it is turned on. What you may have done is reset the remote. It is likely a programmable remote designed to switch to the TV standard it is used with. If it was given to you with the cable box last week, the installer made the choice for you at installation. The website for your cable system is likely to have a an area to help you learn the operation of the remote and how to reprogram when needed. Check there first for instruction if none were left by the installer.

Look on the back of the remote, find the model number and manufacturer's name, and post them.

Or take a picture of the remote so we can see what it looks like.

It's pretty much impossible to help you without knowing what you're working on. The "read the manual" advice is the best place to start.
