Video not showing pitcure, but does have audio


Sounds like really dirty or worn heads inside the unit. If it is just dirty heads, a head cleaner won't shift all the muck off the surface of the drum, as it will collect while the tape is moving past. You will need to unplug the machine from the power point, carefully remove the top cover, access the head drum, and carefully swab the surface with alcohol or methylated spirit (whichever is easier and cheaper to obtain) - do NOT use Q-tips on the drum, use special flat swabs (available from most electronics stores, like Radio Shack etc.) - moisten these and carefully wipe in a horizontal motion, gently rotating the drum in an anti-clockwise direction. Also carefully clean the CTL head (usually on the right hand side in VHS decks) and FE head (on the left side of the drum) also check the condition of the pinch roller (making sure it's not shiny) and the capstan shaft (near the roller) should also be clean. Once done, carefully put the top cover back on (do not put any screws back just yet - as you may need to remove the cover once more to check/clean again) plug into power point, put a tape in, and do a test playback. If the picture appears clearer, you can stop the tape, unplug machine, put the screws back into the top cover, declare the job done. All it will cost you at this stage would be the methylated spirit/alcohol cleaner, and special flat swabs. If you cannot get the swabs, you can use flat strips of clean paper dipped in the alcohol/metho to gently wipe the muck off the drum. I have done this with many VCRs with success.

If cleaning them via this simple method does not improve things, the heads are most likely worn, which means an expensive repair, as they would need replacement and alignment by a qualified technician. Judging by your post, it sounds to me like a simple case of clogged heads which a simple clean should fix - avoid using head cleaner cassettes in the future except in light cases as they are not 100% reliable.

Horizontal lines across TV screen, picture jumps. Unable to adjust tracking [ supposedly automatic]. Could this be the heads slowly dying?


Yes or maybe, or just very dirty.. Get yourself a FABRIC cleaning tape & fluid & try a clean. If still no good.. time for a new one.. head replacement, is probably uneconomic.

Vhs tape from the library...when rewinded, caused vhs player to no longer play any vhs tapes...broike 3 vhs players...any idea?


I know this problem---you put a damaged video tape into the unit---it blocked the video heads up----after they are blocked they will not play back a picture. First: return the suspect tape. Second: you have 2 choices to restore playback on the 3 units. A cleaning tape "may" clear it up but is not a good idea. I usually cleaned these units(yes I am that old that I worked on a lot of them) with a cleaning wand with denatured alcohol--do not use a Q-tip. With the cover removed wipe gently across the heads--they look like razor blades and if it is a four head unit there will be two or more openings in the round chrome drum in the middle of the mechanism-----any shop can open and clean the heads in about 5 minutes each---most shops no longer work on these--I rarely use mine anymore. The cleaning wand has Chammois like a car uses for cleaning up water(Sheep gut).

You could buy one at Radio Shack and some denatured alcohol at home depot---only wipe across the heads--not up and down on them. Look for any black debris on the drum--tape residue-- any black residue will make the tape ride away from the drum.

I do this here for free--so if this helps you give me a vote here. If you need more help or have questions contact me here.

No picture


I assume this symptom appears when attempting to play a tape? If the picture is mostly snow, VCR may need video head cleaning. To do this, take the top cover off- You will note a cylindrical shiny aluminum drum- the actual heads are at the lower edge of this rotating drum.

Anyway, use a lint free cloth or special wipe moistened with rubbing alcohol, or product specifically made for such, carefully cleaning those heads as well as the drum itself. Occasionally, it may take 2 or 3 cleanings.

If the VCR has lots of hours, or abrasive head cleaners have been used, the head could be worn out. If so, toss the rig and purchase a new one. Head replacement is non-economical unless you have a high end machine.

JVC video recorder - replacing rubber band


Not spinning disc If it spins with a little help from yourself replace the spindle motor with improved motor, part number: RXQ0749A Unable to detect discs The laser head was the culprit. Replacing it fixed the problem. (Laser head code GRP6278A) Dew indicator is on permanently. Cannot play or record tapes. No dew present - caused by internal fault This Camcorder uses very fragile flexible circuits to interconnect the PCB's. They plug in to edge connectors. It seems that when they made these camcorders at the factory, they had as many problems getting these film flexy circuits back into the connectors as us service engineers have. I saw one unit that had a crease in the flexy circuit which had caused a hair-line fracture. Solution, trace the wiring and solder a sub-miniature wire across the broken track. Don't disturb any flexy connectors that you don't need to. This camcorder is a **** to work on Not loading properly Usually due to incorrect head alignment or dirty head, or failure of LM324 op-amp Doesn't record properly, ie: looks like one channel is down when recorded, pre-recorded tapes are ok Check Q008 for dry joints

Does it do so on all tapes? It sounds like you are experiencing a tracking or tape path problem. You might try taking the top cover off, then cleaning the video head. Info is available on the 'net on how to do this. If problem remains, play a tape and see it is wandering up/down across video head. See if any of the tape guides are broken or bent, causing tape wandering. you may also have a problem in the electronics, perhaps in the servo circuitry, which has to do with careful control of tape speed, video head rotational speed, and certain other parameters. If electronics are bad, then VCR is likely a tosser, unless it is a high $ rig. Most electronics are disposable these days, unfortunately.
