I did the same troubleshooting as guided by many ppl above. It worked. It was absolutely dry soldering at heater (which I call electronic gun in lay-man term). I removed heater plug which is soldered on a small rectangular cirsuit plate & resoldered all 708 joints. Now pitcture is clear and constant... thanks alot... bye.

Thanks teams for guidence. Just out of curiosity, somebody told me that black coloured trasformer (sylinderical shape) - a very thick wire stretching out from it and connecting to picture tube body with a rubber covering. So called, "FlyBack" transformer, has a huge amout of elctricity, enough for harmful shock to humans, if touched with bare hands. Is my conception correct? If yes, pls help, what precautions to take while testing or soldering such a nasty daemon....

Regards,
