How to Stop a VCR From Flickering

The VCR reads a tape using physical contact. When you load the cassette, the VCR opens the door on the front and loads the tape using rollers. The tape runs over the read/write heads. After many viewings, the tape begins to wear, and you may experience issues such as lines, flickering or audio breakup. Compensate for these issues by adjusting the tracking. If the problem happens with many different tapes, clean the heads.

Step

Check the instruction manual for your VCR for the location and type of tracking controls. Most VCRs have an analog tracking knob or buttons located somewhere under the front panel.

Step

Turn the VCR on and load a regular tape.

Step

Push the "Play" button to start playing the tape.

Step

Adjust the tracking controls. Note the frequency of the flicker. If you adjust the tracking one way and the flicker gets faster, try adjusting it the other way.
