System Error (Focus)


The systems control board has detected a problem with the auto focus lens, the focus is controlled by a tiny motor that has jammed or there is a mechanical issue with the camera lens. It will require a technician that is highly skilled to deal with the situation, but the repair cost would probably not be justified.

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.

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.
