KP342
MFD June 2002
Set has a tic or twitch in the picture with a little jump in the
horizontal, appears PIN related. Scewing is left on top right on bottom with
a little black revealed in the corrners (relitave to scew) . Have
resoldered the horizontal and Pin board, changed out the transistors on the
PIN board, checked caps on PIN and vertical, moved the PCC and Horz width
pots on the pin board, nothing seems to help. The PIN tic/scew/jump goes
away when the pin board is removed from the circuit (there is a slight, but
noticable, pin distortion though). Set is simmilar to the G models
(simmilar setup to most panasonic quazar since 1998 or a little earlier)
except that this set uses a LA7845N as the vertical out not a LA7838.
Voltages on the pin out were low compaired to the G sets. Didn't have a
schematic on this but not sure it would really help. Any ideas?
