Default Panasonic CT32SX31 Pincushion

I posted a problem last week on this set. Thanks for your help. I
repalced the parts that everybody told me except the flyback. Out of
the parts that I replaced, the only bad one were R517 ( 10K ) and the
chip resistor ( R246 ).The others checked fine. I still have the
problem. I have to hit the power buttom many times and when it does
chick I get a high surge pitch and then nothing.At the time it clicks I
get the 140v and the 12 volts supply but then goes away to nothing but
no action on the HV with the probe on the anode. I will check some more
but if Anybody has a few idea's I would appricate it. THanks

Set would not come on. I was checking the epom and found no voltage on
the clock line. It show about 100 ohms to ground. I traced it over to
the Jungle Chip and found pin 29 was the short. I replaced It (IC101)
and behold a picture.And it turns on. However now I have the picture
shifted to the right. About 2 inches on the left is black and the
picture is off the screen to the right. I have to check further...
Thanks
