Why does my VCR play audio but not show video?
The VCR shows the menu but once I play a tape (a known working tape) it shows a blue screen but plays the audio.
What is the make and model number of the VCR?
Have you tried cleaning the video pickup heads, located on the revolving drum in the VCR?
With most VCRs the video heads are located on the drum and the audio heads are located separately along the tape path.
Check if the drum is even spinning.
The audio track uses a small bottom portion of the tape whilst the video track uses the rest, above it.
The reason why the menus work is that the video for them is stored in an eeprom on the motherboard in the player and is not from the tape.
Here's a service manual that may help (it should be close enough)
If the drum doesn't spin, go to p.1-10-10 FLOW CHART NO.7 Drum Motor does not rotate.
If the drum is spinning go to flowcharts No.9 and No.10 on p.1-10-10 and 1-10-11.
