Panasonic NV-7000 videó nem szines a kép "megoldva"
Mielőtt szelektív hulladékba küldtem, gondoltam kap egy sanszot-hobbiból gumi alkatrészek cseréje után próba.
csatolva kép. Egyébként a tartalom természetesen színes. A TV-n színnormát váltva feketefehérré vált nem zöld.
Videón bármit állítok+tracking, nem lesz szín. próbáltam antenna kimenetről és video (BNC) kimenetről. Hang rendben.
fejek pucolva.

VCR Panasonic NV-260 (Esquema eletronico da fonte)

Hello everyone, thank you for participating in this forum. I need the electronic layout of the Panasonic NV-260  video source. I have already researched several lines without success. Does anyone have this electronic schema?
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.

Sziasztok. Még az 1980-as évek második felében vettem a fenti típusú videomagnót Ausztriában. Pár évig használtam, aztán félre lett téve, mert vettem egy sokkal jobbat. Most a rendezkedés során előkerült a szekrény mélyéről, gyakorlatilag szinte új állapotban van. Szeretném rendbe tenni, utána néztem az interneten. Ezt találtam: A Capstain motor három elkójának cseréje után a mechanika elindult. A motor szinkronizációjával még gondok vannak. Talán más elkók is kiszáradtak az eltelt kb. 25 év alatt, még nem mértem végig az elkókat. Ékszíjakat majd cserélni kell benne, de szerintem a jelenlegi hibát nem ezek okozzák. Kapcsolási rajzot és tanácsot szívesen fogadok, mert nincs gyakorlatom a videomagnók javítása terén. Üdv.: Kumi
