Sony SLV- E7 VHS eject problem
This machine has been intermittent in ejecting. The motor's plastic worm gear had split and was occasionally slipping on the shaft. I've repaired that and it seems to be holding but the eject function labours at one point as it raises the cassette, which makes me wonder if that was the cause of the broken worm gear. I've lubed some of the slide points but hard to see exactly where it might be struggling. Any suggestions with this mechanism?
Thanks, Tim Sorry, model number is SLV EZ7 . Couldnt work out how to change it in title. Last edited by TIMTAPE; 7th Apr 2019 at 5:37 am. |

Hi Tim
Your VCR have the S mechanism. Check the following parts. 1. Check the motor coupling for cracks( the part which engage the loading motor shaft with the worm gear. 2. Remove the front panel and operate the VCR observe if the eject function works OK or not. |

Yes the coupling was cracked (split) as I said. That has been repaired now. Quote:

Re: Sony SLV- E7 VHS eject problem
I'm still unsure whether I've fixed the real problem here or whether the same thing will happen again. Does anyone know how often these small plastic worm gears used to split?

Re: Sony SLV- E7 VHS eject problem
Goodmorning Tim
The link is for the SONY S mech https://elektrotanya.com/sony_s_mech.../download.html Check the alignment of the gears. In your machine there is a slide block between main cam gear and eject mechanism. Be sure that it is well lubricated and do not overtight the screws on slide mechanism. About lubrication be sure that you had remove the old grease before apply new. Also check the grease for plastic compatibility. Check also the worm gear for cracks. If the mechanism stuck in eject but you hear the loading motor rotate freely this mean that you have problem on motor coupling or in worm gear. |
