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.

Combo Philips 14PV385 TV+VHS, VHS 11mp-ig müködik.
Sziasztok! Play-re pontosan 11mp-ig mukodik addig minden jó, majd megáll és kidobja a kazettát, és lekapcsolja a TV-t. Elejibe azt hittem TV táp hiba, de a TV mukodik ha nincs bekapcsolva a VHS rész, meg ha kazetta nélkul berakom (infraszenzor eltakarasaval) akkor is megindul mivel nem forog majd kidobja és kikapcsol. Mivel nincs LED-je amivel a hibát jelezné igy kikapcsolással jelzi a hibát, mert ezután nem lehet visszakapcsolni csak áramtalanítással. Ha csak bent van a kazetta (STOP) akkor nem jelentkezik a letiltás hiba. Ha tekerem elore (FWD) vagy hátra (REW) akkor összesen megy kb 20mp-ig. Ilyenkor megindul tekerni majd átvált szupergyors tekerésre, majd 5mp mulva átvált ujból lassu tekerésre, majd hibával kidobja a kazettát és lekapcsol. 2 gumiszij van (lift, capstan tekerés) azt próbára kicseréltem, idlert azt fogaskerékkel oldották meg. Program forgókapcsolót megtisztitottam. Infra adóból 2db van az oldalán hogy a kazetta bent van-e, 1 db infra hogy forog-e a lukas fogaskerék, és ezekre 1db prizmával közösített infra vevô dióda, ezek mind jók letakarva ellenôriztem. Capstan motoron van egy hall szenzor azt nem néztem meg, nemtudom hogyan ellenôrizhetném le. Más szenzort nem látok, nedvességszenzort sem (száraz minden nem az hibázna). Annyit tudok még hogy a tv része az Funai TV-2000 mk12. Nem tudom mi nem tetszik neki, miért kapcsol ki?
