There are white thin horizontal lines across the top 2" of Toshiba 27DF47 TV. Can this be repaired and how much would this repair cost?

Check and replace all the electrolytic capacitors at its vertical output section circuit. There will be five or 6 of them. Replace all.

White lines across the top of the screen

It sounds as though you can see Transmission lines which are sent out with any broadcast at the top of an image, The TV should normally blank these out, i suggest checking your horizontal and vertical settings

How do you fix a white horizontal line across top of Orion TV?

Hello eatkinson,

This denotes a problem with the vertical deflection circuit. This is more then likely the result of the vertical coupling capacitor failing. You will need the schematic diagram of the TV to find the capacitor in question. it is located between the vertical output stage and the vertical deflection winding of the yoke transformer. In addition check the continuity of the vertical winding of the yoke transformer this can cause the same problem. In any event the problem is that the vertical deflection signal is not getting to the yoke transformer or the yoke transformer is malfunctioning.

I hope this helps,

Thank you,

Orion TV, Model STV2763A

This is usually caused by some of the electrolytic capacitors in the vertical deflection amplifier and in the blanking circuit areas. Sometimes it can be some of the other types of components going slightly off specs.

To test the capacitors, an ESR meter or the equivelent is required.

I would suggest sending the TV out to have an experienced TV service tech do this type of work for you. These types of problems can get very involved. There are also some serious safety issues when working on a TV set.

White horizontal, zig-zagging lines

It sounds to me like you're describing the re-trace of the unit. It is repairable, and more so the sooner you get it to the repair facility.
