Hi,

Can you control H-width? I bet you can not, so check horizontal stage.
Damper diode (usualy on same heatsink as HOT) could be a problem.

H.Width control FET or damper diode, usually.

Thanks heaps,I tested all parts on the heat sink and found a A1659A which I
gather is a 2sa1659a fully shorted,all the diodes checked out fine,is it a
FET or transistor there is a big K on the top line then under that A1659A
then on the bottom line Y 124??
