Does it only happen when you use your Xbox?

Try pulling the cable in and out between the TV and Xbox

2 things that will cause that vertical IC or Yoke! Listen to this one went on service call 2wks ago Customer had a 50 INCH1988 pioneer big screen replaced 3 capacitors resolder poor connections TV is now working like New ?

Could be a horizontal output fault, faulty power supply, a simple dry solder joint or HVT. If you can hear arcing or smell an ozone odour, it will be the HVT which may cost a bit.

Without knowing the actual cause, it's impossible to say how much it would cost to fix it.... could be anywhere from $50 to $250 etc

Best to have it checked by a technician and get a quote to repair... then decide if you think it's worth it.

Toshiba is generally a reliable brand, so if you were happy with the picture quality before the fault occurred, it's probably worth repairing.

Cheers

Pls more info; what do you mean tv on, picture froze? you are watching on tv chanel, do you use cable? I can help you but need more details.
