Hello,
Check the back of the VCR, you will see Video, Audio Out and Video, Audio In.
Connect a RCA wire from output of the VCR to Input of your TV.
The RCA comprises of Yellow, white and red. The yellow wire is for visual (display or video) and the red and white part is for audio (sound). Find an image of RCA wire below:
Connect one end of the yellow wire to "video out" of the VCR and the other end to "Video In" at the back of your TV. This is responsible for display.
Also, connect one end of the Red/white wire to "Audio Out" of your VCR and the other end/part to "Audio In" at the back of your TV.
Make sure the VCR is turned on, then press Source/AV on your TV remove and the VCR will display on the TV. Also make sure a VCR Tape is already playing in the VCR so that you can get a signal.
Good luck.
