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

Toshiba 55hx70

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.
