Hello!
I have a problem with my Panasonic NV-FJ620 video. I can't see any mechanical problems more. I replaced a part i nylon which I noticed was just worn. A wheel which "teeth" wasn't so fine. But I think it still was working well. However I replaced it for not having problem in the future when it goes even more worn. But I don't think that was the main problem. The main problem is that when loading a cassette, the cassette just go down the loading process. After that the loading motor changes direction and make the movement in opposite direction. The cassette is thrown out again. What does it depend on ? I have a litte idea. Could it depend on the optical sensors which detecting tape end are worn and doesn't work ? I seems to be a electronical problem. I dismounted the loading motor and loading wheel then I simulated the loading process manually. The mechanicals work 100% and the loading arm goes forward after the cassette elevator is in loaded position. Excuse my English grammar... :-) Hope that you can help me! Best regards SM6SKZ, Roger in Sweden |
