check mo ang Yoke mo. sirain iyan sa mga samsung. 
Check mo rin ang CS503 mo at ang horizontal oscillation mo

wag magtiwala sa ordinary tester sa pagtest ng yoke. gamit ka ng ringer o direct replace na lang

malapit sa jungle/chroma ic iyan ts.
normally open iyan sa ohmmeter kaya needed mo ang crystal tester.. or risky iyong padaluyan mo ng 220Vac in series. then test in voltmeter

kung may madidinig kang whitsler sound ay direct replace ka ng mga snubber caps... double check rin baka may tagas/arching ang FBT kaya ka nasisibakan.. isa din iyan sa mga rason. naway makatulong

Try ako ng china board gumana gamit ang lumang yoke at picture tube. Wala ako makita hv capacitor sa horizontal section .  Pinatest ko rin ang horizontal flyback sa Quiapo at good health daw.

OK FBT dahil pinatest ko sa Quiapo flyback tester store. Saan ba ang snubber capacitor? Ito ba ay parang chicklet na pula may dalawa wire?
