SUBJECT
SOLUTION
Horizontal Output Transistor on
the U2000 and U5000.
The cure is to change D712 to a
germanium type diode. This will
limit the frequency drop and pro-
tect the Output Device. A gen-
eral purpose germanium such as
1N34 will do quite nicely.
PROBLEM
In some cases, operating the
monitor without the remote con-
trol board or if the cable is inter-
mittent or has a broken potenti-
ometer, can cause the Horizon-
tal Output Transistor to fail. This
happens because the horizontal
frequency goes too low and the
collector voltage on the H.O.T.
can exceed its rating.
CAUTION
It is recommended that the moni-
tor not be operated without the
remote cable or control board
attached.
