VIDEO HEAD CLOGGING/CLEANING VIDEO HEAD CLOGGING The video heads are the means by which the VCR reads pictures from the tape during playback. In the unlikely event that the heads become dirty enough to be clogged, no picture will be played back. This can easily be determined if, during playback of a known good tape, there is good sound, but no picture (picture is extremely snowy). If this is the case, have the video cassette recorder checked by qualified service personnel. Good Picture Snowy Picture VIDEO HEAD CLEANING This VCR has a built-in head cleaning system that cleans the heads whenever a tape is inserted or ejected. However, cleaning still may be necessary when the playback picture becomes unclear. The heads can get dirty when playing poor quality or damaged tapes. If the heads require cleaning, use a equivalent high quality chemical non-abrasive (wet) head cleaning tape or have them cleaned professionally. If playing a head cleaning tape in the VCR once does not improve the picture, play it several times before requesting service. • DO NOT ATTEMPT TO CLEAN THE VIDEO HEADS OR SERVICE THE UNIT BY REMOVING THE TOP COVER. • Video heads may eventually wear out and should be replaced when they fail to produce clear pictures. • To help prevent video head clogging, use only good quality Video Cassette Tapes. Disregard worn out tapes. 51
