Found Q777 shorted and Fuse 906 open. Replaced horiz. output and fuse. Set now shuts down with LEDs 953 and 954 going out immediately. These monitor the +/- 27volts to the convergence ICs. The high voltage is present for a second. The fuse 906 doesn't blow and the output doesn't short. I suspect the flyback but don't understand the correlation with LEDs 953 and 954. Removing fuse 906 results in the origional dead set with all 7 LEDs steady burning. this is the AP62 chassis. Does anyone have the part no. for the Deflection/sweep board. Any help appreciated.
