Currently I have a 472J cap in.
If I change it to a 4.7uf the picture is to small....

Why did you change the value from 4.7uF which is correct to 0.0047uF (that's what 472 is)??
If you can't adjust width and you have a pincushion distortion it's because the correction signal from T19 is either missing or it doesn't arrive at the diodes. I'm wondering if the bridge/width coil is the problem. Or R135.

Hi
THANKS! ;D :notworthy:
It where R137 that where dead! :cheers:
Put in a new 10 ohm resistor, and now I am able to adjust picture :applaud:

I don't work much on these later POLOs and I didn't notice there was a resistor in series with the EW signal until I looked at the schematics last night. Earlier Hantarex chassis don't have it.
