SYMPTOM: Set is dead, line fuse is open. Further inspection reveals Q551 is
shorted.

CAUSE: Horizontal Output Transistor Q551 has failed due to excessive reverse
bias across the

collector-emitter electrodes. This may have resulted from turn-on and
turn-off transients, hydro

line transients or the like.

REMEDY: Replace Q551 with the improved type (available in kit form). With
most models, it will be

necessary to change resistors R510 and R511 as well, to reset the H drive
T501 primary

saturation current. Please refer to the following listing for kit
application and ordering details.

NOTE: The new type transistor is larger. Use caution when forming the leads
to fit the PC board and

the heat sink. Apply silicon compound to the transistor surface prior to
securing it to the heat

sink.

Does anyone have a manual for this?? I'm looking for the original
Output Transistor # if anybody has it.

This TV has blown the output every year for the past 5 years( 5
differant shops).. Now I've ended up with it for repair.. Any help
would be great..

Thanks in advance.
