Question about Toshiba 32A50 32" TV
The fault is a failure of the deflection circuit and since you have not specified whether it is a vertical or an horizontal line the section failed will be related to the position of the line.
If horzontal the vertical IC or the section related is faulty and if Vertical the horizontal section., Now this can be the deflection IC, teh deflection coils or even discrete components like capacitors or resisitors in this section which will require a signal trace with a voltage test before the absence of the sync pulses are confirmed and the section identified.
I request not to change the IC unless it is proved but you can solder the vertical IC or the section concerned -- if there is dry soldering.
