this set came in with blown HOT ( 2SD2645 ) & D614 measured open I replaced them
but set woulld not come on ( no HV )  B+ would come up to 135v for a few sec 
and 
then would shut down
I went ahead and changed MCZ controller-error amp DM58- and opto and still same 
results
Here is what  I have  D621 = 14v    D615 = 19.5v ( s/b 14v )  IC603 ( 9v reg OK 
)
non of scan derived volt  (  FBT )come up at all so I had a HR8579 on shelf 
which i installed with same results
And then for good measure i replaced vert IC & TDA on CRT brd.  I seen tip to 
check R591 = ok
I haven't scoped any thing yet cause my scope is at new store and i am woking 
out of my house
I am thinking that whatever made HOT blow is the root of my problem but can't 
seem to put a finger on it
Maybe someone can help with some info
Thanks
