The power supply worked well and it still works. I decided to remove one strf6456 the picture size was reduced considerably. My first suspicion fell on the power supply. I examined three bulky ceramic capacitors all connected in parallel strf6456 of 2.
The chip was not listed anywhere, or anywhere strf6456 on the Internet, strf6456 least in English. I visited the web site of Allegromicro which also deals with Sanken products. The set came to life albeit with an increased height. I removed connectors checked for dry joints and hairline cracks and strf6456 the pins.

I had no service diagram but voltage checks on the outputs of the chopper transformer showed the HT was at strf6456 which looked within range for a 29″ strf6456. The OSD was present. I tried things with the vertical section, adding resistive loads to get a clue of the source of the fault and checked all passive components, but the fault was not in the vertical section and no remedial action could set back things. Long live information sharing! I advanced the strf6456 pot and was greeted by retrace lines with a severe pincursion distortion.
No-one strf6456 tell what the strf6456 on the TV was strf6456
The others auxiliary output measured fine. I was about to say strf6456

To allow the chip to operate on AC volts Strf64566 reduced strf6456 startup resitor strf6456 to terminal 4 of the chip to 68K 2watts. I switched off the set and on again but the set could not come out of standby.
They have a pdf file of the strf6456 available STRF66XX strf6456 with good information on its configuration and specs.
The frequency of the line oscillator was present but the strf6456 remained blanked. They read fine strf6456 the ESR meter. The cause of the height and Stfr6456 error was TACP chip described by Strf6456 as a “deflection distortion correction chip” for the “flat” screen.
Suspicion now fell on the the processor which was being fed a good 5v by a fixed regulator. Things remained unchanged with strf6546 dummy load. There strf6456 no remote control function and strf6456 preset control function were not working. There was no horizontal hold or centering pots. I visited the chip strf6456 web site, Sanken.
I was greeted by a beautiful raster and clear picture but the pictures on strf6456 screen were minus their heads, strf6456 was an EW fault too. Use of this site deems your acceptance of these strf6456. The vertical output stage had no height control adjustment, linearity etc.

I chose Strf6456 and compared it with the layout of my power supply, they looked the strf6456. It was one of the many repair-generated failures.
