You have convergence output failure. The output ICs will need to be replaced and possibly a small component like a resistor or two as well. Expect to pay a service company $350-$450 to resolve this.

Toshiba 50H72 have blue and yellow ghosts


Sounds like your convergence circuit went out. It lines up the red,green and blue picture tubes so the colors are lined up. Usually these TVs all use the same type of IC chips called "STKs" both usually get replaced along with any resistors etc.. around these chips that may have burned up. Depending on who fixes it could be around $300-400 parts and labor.

Toshiba 55hx70


check all the fuses. Its easy to mis the 2amp pico fuse mounted near the middle of the power board. When this fuse opens, the red at the top, especially at the left side of the screen, will not adjust enough. Be sure to use new heatsink compound behind the ic's Shutdowns,are usually,not an easy repair Good luck
