You have a bad capacitor in your vertical area.

My 15 year old Toshiba Televisiononly shows a narrow horizontal band in the middle of the screen. Sound OK.

Hiii fairley,

You aren't specsificly dercribe yor tv set.
For common TV horizontal problem ;i.e : White line accross the horizontal screen, horizontal band,'s can solved by replacing the IC Vertical/Transistor, and olso to replace the cap nearest the IC.

For common TV Vertical Problem :i.e : White line at the center of the screen (top to bottom),Vertical band,etc...It's can cure by Replacing the Horizontal IC/Transistor,and offcurse the cap's.

Tha's what all I know....

Hope can help you to solved the problem.

the vertical drive ic that drives the yoke for vertical sweep has blown.
sometimes it is solder problems like sharp and toshiba had.
the part is 10$ the pc board will label it ,the yoke is the coil setup on the picture tube.if you follow the wiring half goes to the horizontal drive,and the others to the vertical section.the chip drives the coil directly.there are VERY high voltages in there ,even turned off. the pix tube cap on top is 30000v. like a stun gun.the horizontal drive 2000 volts and the main power supply 165 volts dc high need a special setup to discharge the picture tube.

Toshiba TV CX2789K Horizontal Line

Failure in the vertical deflection amplifier section. This is usualy from failed components, and sometimes cold solder connections. Most of the time, I found bad capacitors, and sometimes the output IC or transistors (depending on the model type) that have failed.

Take the set to a service center for an estimate. You may find it more feasible to buy a new set depending on the parts that failed and the time involved to do the work.

Tv showing blue screen with flyback lines sound ok

Flyback lines? Is the picture all white with no brightness control with faint horizontal faint lines? If this is what you are saying, the screen voltage could be bad, and if thats the case, the picture tube or the flyback itself could be bad. You could also have a bad connection on the crt socket
