OSD--On Screen Display
CFM--Confirm (used to confirm program settings) No idea on the other ones.. VCR repairs "back in the day" were 90% mechanical. Worn/slipping/broken belts. Idler tires/clutches, or damaged front loading mechanisms. Lots of dirty/damaged video heads from playing creased/poorly spliced rental tapes. Early VHS units used incandescent bulbs for the tape end sensors, and the bulb would burn out causing the unit to lock itself out to prevent tape damage. Main electrical problems I saw were Panasonics (PV-1225 and others) with burned up SMPS. Most units used linear supplies, which were usually pretty reliable. Now, of course, these things are getting into the age where leaky or dried up caps start to become an issue. Last edited by N2IXK; 09-12-2014 at 09:00 PM.
