Typically this is a convergence problem and can be repair relatively easy. Refer to this video to determine if you truly have a convergence problem. Also make sure you use your TV's original remote to make this adjustment.

TOUCH FOCUS ERROR on Projection Toshiba TV


My 57H81 won't converge, plus I get the "touch focus error" message. I could get manual convergence of blue, but not red. Plus, during touch focus the red would not move horizontally

TOUCH FOCUS ERROR


The convergence IC`s need to be replaced and the related low ohm resistors need to be checked for proper value.

Touch Focus Error


Even if the pix appears to be "OK", the internal convergence

alignment (in servicer mode) must be accurate within certain

parameters for the Touch Focus function to complete w/o error.

Adjustments should be done in "Full" mode,both HD & regular

signal.
