Question about RCA F19426 19" TV
Mr. Pravin .ihave tv samsung model#tc9865tb. burn up resistor 1olm repeated right by flyback, when power on. power supply, horizontal output & vertical output ok.
Check very carefully for cold solders on horiz. drive transformer also replace the electrolytic cap that shapes the horiz. drive signal - if you have a scope and manual compare the drive signal shape.
Some times using poor after market horiz o/p's also causes the problem - does the o/p heatsink get to hot to touch or does the horiz o/p blow immeadiatly?

Testimonial: "In my first post I said: No horizontal & vertical drive from IC001 jungle chip. And I say a little further: IC001 still have no drive output. I obviously checked with a scope. You suggest: with a scope compares the drive signal shape?? Something wrong with your analysis. Thank you anyway."
