SANYO CTP 5101

The trouble is arcing from the flyback transformer T904,
where the lead goes to the e.h.t. rectifier. Does this mean
that the e.h.t. is too high for some reason, and how do I go
about testing when the arcing starts immediately the set is
switched on?
This is a fairly common fault on these sets, and is due to
the insulation breaking down around the high -voltage
connector. The only cure for the problem is to fit a new
transformer.
