My screen just powers up to a horizontal line. Does the smaller backup battery need replacing? Is something else wrong? Thank you.

Horizontal lines across whole screen

Bad inverter, or a dirty one. Remove the power cable and battery, then take apart the screen bezel, or casing. Remove the LCD by unhooking it. Disconnect the inverter. Clean it. Reconnect it. Fixed.

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.

Won't power up, flat line across screen - battery problem?

Yes, this sounds like you'll need to replace your back-up batteries. That will probably resolve the problem.
