Question about Sanyo DS20930 20" TV
When I turn on the TV I have a small white line across the middle of the screen...After a bit of wait time the picture above it stretches and the line moves to the bottom. After a bit more wait time the white line begins to stretch upward and it takes quite awhile but the picture is fine. This entire process takes close to a hour.
Based on your post, the TV unit is suffering with a Vertical collapse. Further, your description indicates that it could either be a capacitor problem or a cold solder. Though of course there are instances that it could be the vertical IC that may be defective.
This is a relatively easy repair and the part should not be expensive. If the problem is a cold solder, then simply reheating the solder joints with a soldering iron should correct the problem with no parts replacement. Even if you were to do a shotgun approach and simultaneously replace the IC and capacitor, again would not be that expensive.
However, the repairs do require that you be a bit familiar with electronic components and circuitry and the use of a soldering iron (with a desolderer). Should you not be comfortable dgoing this router, perhaps you can seek the assistance of a friend with soldering experience. otherwise, your best bet maybe to seek the services of a qualified professional.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
