I know 'no filament' is oversimplifying. Unit has HV, sound and vertical. Everything including video amps are operating like everything is fine, but no raster. Had good video once for 10minutes or so, then went out. Tried to be clever and floated the heater pins and did the wrap around the fly core.I had 1/4 screen but smeary at that. Changed the fly, but nothing. Checked continuity from the fly out and it's good. Of course no prints so could use a pointer or maybe a scan of the sweep circuit. Man I hate these. Any help appreciated. Thanks.
