Question sony 53xbr25 2 scrolling bands, please advise

on a 53xbr25 there are 2 bands one light one dark they are always about a 1/3 of the screen apart and the move from bottom to top whenever you use the s-vhs inputs ( dvd or satellite ). it takes about 6 seconds to go from bottom to top. any ideas would be greatly appreciated. thanks

Thumbs up

Your problem is shield grounds or bad solder connections within the set. What you are seeing is 60 Hz AC from an adjoining line in the set that is radiating over to the the signal line. Since the Vertical circuit runs at 30 Hz, you should see at least two of these bands on the screen all the time.

Bad solder connections. This can be cured with a low heat soldering iron and a little 60-40 electronic solder.

Need a service manual on the set: try our friends at
