I went out on this sony projo a while back. The customer complained of
a
convergence problem. One of the fuses was open on the convergence module.
I replaced both fuses and both convergence IC's. I did use quality IC's
from B&D. Now my convergence is corrected but the picture is narrow on the
sides. The sides are not bowed it is just too narrow. I have noticed that
Q508 (Pin-Out) runs pretty hot. Is this normal? I do not have the exact
schematic for this model but have one that is close (KP-53V15). I have
checked the following components in the horizontal circuit: C569, C502,
C522, C510, C512, R509, D507. Is L501 the horizontal linearity coil a
suspect problem on this chassis? Any help would be appreciated. Thanks
much. Shannen
