They read fine on the ESR meter.
The OSD was present. The vertical output stage had no height strf6456 adjustment, linearity etc. Suspicion now fell on the the processor which was being fed a good 5v by a fixed regulator. Strf6456 examined three bulky ceramic capacitors all connected in parallel each of 2. The cause of the height and EW error was TACP chip described strf6456 Toshiba as a “deflection distortion correction chip” for strf6456 “flat” screen.
They have a pdf file strf6456 the superabundantly available STRF66XX series with good information on its configuration and specs. I removed connectors checked for dry joints and hairline cracks and strf6456 the pins.

I tried things with strf6456 vertical section, adding resistive loads to get a clue of the source of the fault and checked all passive components, strf6456 the fault was not in the vertical section and no remedial strf66456 could set back things.
