Which components is responsible for the auto tracking in the sony vcr, model slv d380p


Auto tracking, or 'digital tracking' as it is sometimes known, is generally governed by the CTL (the linear control track head), located toward the right-hand side of the main head cylinder drum, along with a combination of the guide posts/rollers, the capstan speed as the tape travels in the deck, and of course the drum balance since this rotates the fastest. Usually this is pre-aligned to factory standard, but as parts wear down, the alignment changes - hence your 'tracking query'.

Presuming you have a video picture from your tapes on the TV screen, you can bet the tracking is controlled electro-mechanically (as above). One of the first parts on the mech to wear out is the rubber pinch roller - when it becomes glazed or shiny, tapes can be chewed and/or the 'control track' drifts during playback - more so than when recording.

Nevertheless, it is usually a simple workshop repair involving inexpensive part replacement/alignment on the mechanism including a new pinch roller and cleaning of the entire tape path. The only 'cost' would be labour on top of the parts. The option here is that you can submit your unit to a workshop/service centre for a quote on repair/parts costs first, then decide if you want the tracking fixed - up to you. I hope you have no other really serious issue with this combo unit - SONY is a premium brand - trusted and reliable. I assume the DVD section works fine.

Remember; bad tracking is not always a mechnical mis-alignment - it can also be the quality/age/condition of the tapes a person uses as well, even if that person doesn't 'thrash' tapes on a daily basis. From memory, the SLV-D380P is one of SONY's better DVD/VCR combos.

My player eats the vcr tapes!


It is most likely that the pinch roller will need replacing. Once these become glazed (shiny) the tape slips over them, resulting in 'chewing' as the edges of the tape ride up or down the capstan shaft and into the top or base 'rabbit' of the exit guide nearby. Replace the roller, clean the tape path (capstan, guides, heads, take up arm, etc., *gently of course*) with alcohol solution or methylated spirit - do not use q-tips to clean the drum.

VCR should be OK after that. No further repair should be necessary here, and rubber pinch rollers for VCRs are not expensive to order as a generic part for this model.

The capstan drive roller on my tape deck fell apart. Spindle is .0975" dia. Pinch roller is .862" dia. All other belts and rollers seem OK. Where can I find a replacement capstan roller? Thanks.


You need to locate the supplier of pinch rollers that will fit your tape deck. If that fails, you have a useless piece of gear. If the unit is of decent quality, you should be able to locate a supplier. You didn't include the make or model, so good luck.

Likely capstan motor and/or pinch roller worn. Probably more than new VCR.

Sounds like the pinch roller isn't engaging. The pinch roller is a black rubber wheel that presses against a silver post (capstan) the tape is held between them. With the door open and no tape press play. The roller and capstan should touch. If it recently ate a tape there could be some tape on the capstan that also will cause it to run fast.

VCR Eats the tapes


Often the "Pinch Roller" type Tape Drive can "Dry Out" and it slips. this causes the tape to get all screwed up.. It could also be a belt that turns the capstan.. Or even a thing called the "Mode Switch" In any event Ya probably be best to take it in for repair as it's not really a "Homer" I suggest ya get a quote and an explanation, and see if it is economically worthwhile?
