Panasonic CT27G4A

[Jim]

This set has no raster. Unit has HV for about 1 sec when turning on, but
goes into HV shutdown. A series light bulb test indicates that there is a
short. I've replaced IC451, IC803, Q551, Flyback, C454, C459, C815, C805,
C806, C823, C555, C552, C561, and C556. Any other ideas of where the short
might be?

Do you have the equipment to drive/test the H sweep circuitry with the set
off (ala Sencore?)

What happens when you fire the set up with no light bulb?
