TV Horizontal Roll
Hello, Nick!
You wrote on Fri, 17 Mar 2006 18:46:56 -0800: N Panasonic 29ad2 N The picture is rolling horizontally until it warms up. It was N suggested it N could be a capacitor on the tuning circuit. It also rolls form a N video tape. N if this is true how do I recognise the tuning circuit? N is it in one of the shielded tin boxes? N I have sprayed all the caps I can see with freeze spray to no avail. N I would be grateful for any suggestions? N Nick HORIZONTALLY?? are you sure you don't mean Vertically? Vertical roll would be much more common, also if the roll is present with a signal from the VCR then the tuner is innocent and the fault lies in vert oscillater. if the roll is horizontal then signal line sync is being lost. It's still not the tuner however which incidently will be in it's own little can. If sync circuits are suspect there would be line tearing and not smooth rolling. With best regards, 3T39. E-mail: |

No,no...there's a little guy standing on it wearing a hard hat with a
flashing light on top, waving a flag that sez: "tuning circuit" JR Just Another Theremin Fan wrote: if this is true how do I recognise the tuning circuit?
