I have a new Black Bar Problem with this set in for repair. Black Bar
in center of picture. In the past this has been a tempature related
problem with the TCHIP as set warmed up black bar would appear in
center if screen. Cooling the T Chip would correct thr problem, But
this is different. Black Bar is in picture when turned on & does not
change cooling does nothing heating changes nothing.
I have changed thr r-c network on input to vert IC as well as the Vert
IC its self I am now looking to the scan loss Circuit. Has any one run
into this or am I just LUCKY. Any Ideas welcomed
