its not always going to be channel 3, it depends on the input cable you are using, if you are using an HDMI cable you need to switch to the hdmi input, same with component, and if you are using RCA cables it will probably be called video. Try your other inputs dont just stop at channel 3. If you are using coax and its supposed to be on channel 3, make sure you are on the correct coax jack on the receiver, make sure its the "to tv" jack not the "to wall" jack.

If your Sharp television has RCA jacks, you may use them through your VCR. Your VCR would have to have a tuner and then you may use this as a means for getting a signal. Newer VCRs and DVD players generally do not have a tuner. Thanks for asking!

I do not see a question. "Which input goes with the cable channel?" Don't understand. Is there a cable box or SAT box connected to the TV? What kind of cable is running to the TV from the source? If you just have the coax cable going from the wall to the TV, then you need to auto format the channels. Select menu on the TV remote. Find Sources or Cable. Select "Cable" not "Air". Select Auto Format. May take several minutes. Input selector from TV remote should be "TV".

your line in or front RCA yellow/white/red cable input is usually defaulted to channel -1 and is accesible by either pressing the tv/video button on tv or remote or sometimes by scrolling down channels past 1

Use channel up or down buttons, the inputs are usually in between the highest and lowest channels you have programmed, or if you have a remote try entering channel 90 or 91 another possible is enter 00.

tune your tv to channel 3 if you're coax cable, if you're using rca or component cable then tune your tv to the proper input on your tv.

These are the codes printed in the owners manual for your dvd/vcr player.If they do not work you will have to contact Emerson and ask them for help getting the code. The contact number should have come with the instructions for the remote. Just give them the model number of you remote and the units model number and they should be able to help you. I hope this information helps you with your problem. Switch the input selector on your TV to an appropriate external input channel (usually near channel 0).
Press a button on the TV’s original remote control that selects an external input channel until the DVD
recorder’s picture appears. Check your TV owner’s manual for details.

on some of these older RCA try simply tuning it from the remote down to chanel 01 or 00 this may work. if not you have to go into the setup menu of this set and enable the aux inputs

You can purchase an RCA universal remote that will let you access the A-V inputs. These only cost about $10.00 or so. Stargazer

Try the old RCA/GE channels of 90/91 or 92 to get to the inputs. Or try entering channel 00. Let me know if that works.
