Will only display on ch 3

The ones i know are 0047, 0240, 0104. If they do not work, try searching for the code page 10 in your book

The simplest explanation is that you are using a video tape that has it's protect tab removed. Covering the slot with tape will solve that. However if the tab is there, it might be that the switch inside it pushes on is bent or broken.

I assume that you are coming in on channel 73 because you don't have a line level input on the display (tv) you are using. If that is the case, your options are limited. If you DO have a line input to the monitor, run the VCR to that input and just switch to that input when you want to use the VCR. If you have RF in only, -that would be the screw on type connector- you would have to have the same kind of output on the VCR. Understand, the VCR will be outputting to channel 3 or 4, so you would need a 2x rf switch, and you would have to change from channel 73 to 3 or 4 whenever you wanted to watch a movie. There may be other options, but I don't really know what you have.

the output of the vcr...
what is it physically wired to?

I would love to say we can help, but the truth is, you remote needs to be replaced. One of the advantages to have the remote is that you wear out the remote, not the controls on the tv. And replacing a remote is much cheaper. You have done all you can to save this remote. You will need to replace it.

CH

1. Set tv to channel 4
2. insert a pre-recorded tape into vcr.
3.press play once to start playback.
4. after a few seconds press play on the vcr for 3 sec you will see a playback picture.
when a picture doesn't appear on the tv screen repeat step 4.
5. press stop to stop playback.

lost manual need codes

Go into setup thru the "Menu" or similar button on the remote and you should see the "Language" option.

I suggest you get the Tape path cleaned up. Could be dirty video heads or a dirty Control Head. Use a good 'wet' type cleaning cassette.

there is a switch at the back that you can to channel 4 or 3 good luck
