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.

I have a rear projection Toshiba 42 inch and cannot get convergen


Sounds like convergence should replace chips marked Q 751 and Q752 part numbers ( stk392-110) check restors 1.8 ohms 1 watt rateing should be marked on board as R 7721 and so on, should more than one in the area of the ic. Look to see if there is some small fuses in the area also. They dont look like a normal fuse may be yellow or green black marked F on board around the ics these fuses are called pico fuse.
