Flyback was arcing badly, replaced, works, & looks perfect,
but momentarily shuts off, & right back on, even before you
can look back at the set. may work for hours, or happen twice
in a half hour. Unplugged the customer controls on top of the set,
to make sure the "tact" switches aren't "leaky". Anything common
here? Nothing on the Thomson B2B website. Sky.
