Magnavox ZV457MG9a problem

assuming its a mechanical noise, not noise on the audio, check the back tension on the supply side

The "snoring" sound coming from the VCR part of my Magnavox ZV427MG9A (DVD recorder / VCR combo) is from the hardware and not audio. This sound has just been noticeable for about a month now and is audible from 25 feet away, either in play or record modes and with multiple tapes, including both

6 & 8 hour tapes. I've had this unit for a year, as the original purchased unit lost vertical sync and was replaced after 11 months under warranty, by FUNAI as a "reconditioned" unit.

I can find nothing to adjust the brake (tension) straps on either of the supply or take-up reels or nothing to bend.

A stethoscope indicates the loudest "snoring" sound is coming from the VCR tape cartridge, regardless of which cartridge is in the machine.

Haven't found any help with this specific problem online from Magnavox or FUNAI.

the cartridge is probably acting as a resonator, so perhaps misleading. What happens to the sound if you manually move the braking actuator pillar in and out? The other possibility is part of the slip clutch assembly is worn/misplaced and some part is rubbing on the deck or even the underside of cartridges.

Thanks for your replies; your theory is correct but I haven't found any means of viewing or accessing the straps when a cartridge is in place. Also, I have been unable to find a parts list/manual for this unit.

I have determined the location of the "snoring" sound. There is a flat plastic part which has a piece of rubber-type pad on one end and about 180 degrees on the other end is a spring; this flat plastic part has a pivot hole in between the two ends. The "snoring sound is coming from the rubber-type pad which is held against the supply spindle, on the same surface that the brake strap rides.

I removed this flat plastic part and the "snoring" sound is eliminated. But this flat plastic part is required, because the the rubber-type pad is used to apply drag against the supply spindle during sudden stops (such as during fast forward or rewind).

There is no visible wear on the rubber-type pad or on the supply spindle surface which it rides. I cleaned the surface of the rubber-type pad with a pencil eraser and that did not change the "snoring" sound problem. I thought about putting a oil or silicone lubricant on the pad surface but that would also affect the function of the brake strap since both ride on the same surface of the supply spindle.

Suggestions would be appreciated.

UPDATE ON VCR SNORING NOISE: after running more tests, i found that the "snoring" sound only happens in the SLP speed, not the SP speed. and MAY be associated with the belt that drives the spindles. i can see a portion of the belt through a hole in the motherboard, and with a wet Qtip, moistened the inside of the belt, which solved the noise problem for a short time. After drying, the noise returned.

since removal of the belt would be a significant task (because to remove the drive assembly, requires removal of motherboard from case), is there any acceptable "belt dressing" available that i could apply with a Qtip?

Fedron. Perhaps it is available from Shop Jimmy. Ness used to carry it.

talcum powder is useful against belt squeel, dusted in on a small paint brush perhaps
