VCRs also act as broadcast receivers, the same as a TV but without a screen, a nd can cause impaired reception if faulty. With the aid of your manual, check that the controls on the VCR are all set correctly. VCRs can be susceptible to interference from nearby radio transmitters. If the reception difficulty remains, check to see if the reception problem looks like radio interference . With the help of your TV handbook, check that all your TV controls are set correctly - including those which are seldom used.
Some controls can cause reception difficulties if accidentally adjusted to the wrong position.
If possible, try substituting another TV or VCR, remembering to switch off the original equipment. Connect your antenna to the second TV or VCR - if the reception has improved, the original receiver is likely to be faulty. If both receivers are affected, if possible, check to see if your neighbours are experiencing the same interference problem. If your neighbours are also experiencing the same reception problem, it is likely the reception problem is caused by some sort of interference to the received TV signal in your area. If your neighbours are not experiencing the same reception difficulties, check your TV antenna equipment.
