Sony Sl-S770 vcr interrupted playback and AV display issues

I'm encountering an issue with my Super Betamax player. During playback, some cassettes abruptly stop playing at seemingly random points, accompanied by a sound similar to the one made when a tape reaches its end. This interruption also renders the rewind and forward buttons unresponsive. However, it does not impede the manual forwarding or rewinding of the cassette. The only solution seems to be ejecting the cassette and reinserting it. Occasionally, even this workaround fails, allowing only two seconds of playback before the problem recurs.

I sought guidance from the Mister Betamax troubleshooting page, which indicated that the tape safety device might be the root cause. I received additional advice suggesting that the issue could stem from one of the sensors within the VCR, possibly due to oxidized contacts causing intermittent operation. It was recommended to resolve this by carefully cleaning the contacts on the sensor switch responsible for detecting loaded tapes or the sensor that detects if the tape is "record-protected." Another suggestion was to monitor the output of these switches using an oscilloscope or voltmeter to determine if they are indeed the source of the problem.

I'm eager to hear if anyone has additional advice or personal experiences to share regarding this issue.

Additionally, I'm facing an AV cable problem where the yellow AV cable fails to display any video. While it used to work correctly, the AV audio cable still functions properly. As a temporary workaround, I've been using a coaxial cable and routing it through another VCR to utilize its AV output. However, I'm interested in exploring potential solutions to fix the issue with the yellow AV cable, if possible. Any insights or suggestions would be greatly appreciated.

Sony slv-x57 javíthatatlan?
Sziasztok! Apum kitett magáért. Van egy címben szereplő video, azt mondták neki nem érdemes megjavítani, erre miszlikbe szedte :( Miért nem hallgat soha rám... Ki ismeri ezt a gépet? Netán tényleg egy gagyi gép és nem volt kár érte? Üdv: Pityesz
Sony SLV-X9 némely kazettákat csak fekete-fehérben játszik le (megoldva)
Sziasztok. Családi VHS digitalizáláshoz többek tanácsára vettünk egy állítólag alig használt 6 fejes sony-t, aztán nincs is vele nagy baj némi fejpucolás után, egy két szalagnál ugrik néha néha a függőleges szinkron, van amit szépen lejátszik de csak fekete-fehérben, van amit meg hibátlanul lenyom. Van otthon egy szintén hat fejes samsung valami, ez meg alul csikozza a képet, mintha a szalagpálya nem volna rendben. Kínomban előszedtem a régi Fishereket, ott meg szíj és idlerproblémák vannak. Úgyhogy egyenlőre van négy videom amit nem tudok használni amire megvettem. Mindenfél tanácsot megköszönök, nekem ez a vhs technológia mindig is bonyolult volt. üdv András Update: Sajnos a videomagnó német piacra készült, így csak a PAL rendszerű felvételeket ismeri. A házi vhs kamerák szerencsére PAL-ban rögzítettek, így amire kell arra jó lesz a magnó (digitalizálni). Mindenkinek köszönöm a segítségét!
