Schneider SVC618 videómagnóhoz alaplapot keresek.
A panel tápegysége rossz. Minden szóba jöhető alkatrészt kicseréltem, eredeti, belevaló példányokra. Táptranzisztort 2SC3717, az emitterében lévő 2.7 ohmot, a tápelkót 22uF/450V, ami ki volt száradva, ez lehetett az alapprobléma, mert egy hálózat kimaradás után szállt el. Cseréltem még 2 db 1N4148-as diódát, egyikük mérhetően rossz volt, a BC639 tápszabályzó tranzisztort, és a hozzá kapcsolódó 817-es optocsatolót, a szekunder körben lévő LM 431-et, és az 1.6 A-es biztositékot. Bekapcsolás után semmi áramfelvétel nem volt, a tápelkón a teljes gyök 2-vel felszorzott egyenfeszültség volt, kijelző nem világitott. Mire elkezdtem volna mérni benne, egy nagy villanás, elszállt a biztositék, és persze a végtranzisztor. Itt feladtam a küzdelmet, és Hozzátok fordulok tanácsért, mi tévő legyek. Szivemhez nőtt a gép, nagyon jó állóképe van, sok márkás terméket meghazudtolva. Ez a funkció fontos nekem. Sok gép megfordult nálam, köztük még a Grundig GV470 is, ami egy 7 fejes, professzionális gép, de ebből a szempontól nem vitte a pálmát. Arra is gondoltam, hogy megoldás lenne, ha tudnék egy mechanika hibás példányt venni, aminek jó az alaplapja. Csatolok egy rajzot, ami kicsit egyszerűbb, de hasonló..A válaszaitokat előre is köszönöm.

Tiszteletem a tanyának! Arra várnék választ, hogy emlékeitekben rémlik-e olyan VHS videomagnó, melynek volt S-videó kimenete? Esetleg a típus megjelöléssel. Válaszaitokat előre is köszönve: exGelkás
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.
