It depends on what kind of a connection you have coming out of your VHS VCR.
The best way to connect stuff to this TV is via an HDMI cable, but your VHS VCR may not have an HDMI jack.
It is more likely that your VHS VCR has one of the following: A component video connection or a composite video connection.
Unless Panasonic has changed what the TV comes with, they package it with an adapter that allows you to hook ONE component cabled device up to the TV. (Component cables are the ones where the video signal is sent over three cables - usually a blue, a green, and a red connector - and then two for audio - usually a white and a red connector.) On this TV, you'd plug all five of those into the included adapter, and then plug that adapter into the back of the TV.
If your VCR is MUCH older, it may have a composite cable coming out of it. Composite cables send the video signal over one wire (typically with a yellow connector) and the audio over two wires (typically red and white connectors). In that case, you may still be able to use the included adapter with that type of wire.
Depending on the connection for the VHS player will depend on how you hook it up. This comes with an attachment that you can connect to your RCA cables to. If you need more attachments for RCA, you can purchase a splitter for RCA connectors but this can be done.
Assuming you have a standard VHS player, you will have some form of analog video output such as composite video (usually a single yellow RCA connector on the VHS player), or possibly S-Video (has a round DIN4 connector). There is a single analog video adaptor for the analog input for this TV. Unfortunately, it will only accept the composite video and audio inputs from your VHS player. This TV does not have an S-Video connector. If you are fortunate enough to have a VHS player with an HDMI output connector (found on DVD/VHS combo players in my experience), then you can use one of the HDMI inputs on the TV to view the output of the VHS tapes on your TV.
