Video is slightly smeared. ESR'rd the caps aroud flyback and video
drivers. Anyone have any info on this symptom on this model?
Thanks, Lenny Stein, Barlen Electronics
 
"Y" line Zenith 25" around 1995?
#1 failure for any kind of video smearing, CRT.
#2 failure, if the model has Q5104 on the corner of the crt pcb, it will be
bad, G1 control transistor.
#3 failure, 180K resistors on crt pcb, causes loss of colors.

Always test a Zenith 25" and 27" crt if the tv was made between late 1992
and late 1997 before wasting much time on the set. Bad thing though, many
of the failures will not show up on a standard crt checker, hv to g2
leakage, G1 to G2 internal short, etc.

The problem was Q5104. Thanks David for the help!
