How To Change Input On Dynex Tv Without Remote

My Dynamics TV doesn't have remote control and I accidentally switched the TV input. 3

I accidentally put the remote that came with the TV in the washing machine: / then used the Comcast remote. But when I increase the TV volume, I accidentally change the channel and switch from Channel 3 to Channel 51. I tried resetting the TV buttons, but it only reaches 50, 51 and 72. What am i ? He does ??? Help

Apparently you have removed Channel 3 from the Channel list. Instead of trying to rearrange manually, you can easily run the TV's Auto Channel Search feature. Let the TV rearrange the list. Make sure the cable box is on. You can search channels using the TV control panel without using the remote control. Press the S menu and find the Channel Setup tab. If necessary, consult your bidder's manual for instructions.

If you do not have a manual, visit the TV maker's website. Find a guide to the TV model you are using. As a rule of thumb, you will need Adobe Reader (you can download the free reader from Adobe) as it is usually available as a .pdf file.
