dagdag ko lang mga masters wala din pala sound pero paglipat channel magkakaroon pero mawawala din agad . yong regulator na sinasabi ko 5 pins 5 volts regulator siguro yon. yong isa IC851 pin 1=3.3 volts 2=9.5 3=0 4=5  5=1.4 tapos yong IC880 pin 1=2.6 volts 2=10.2 3=0 4=3.4 5=1.5 pareho nakasulat sa 2 regulator OOBCOW 748 HO6. thanks sana matulungan nyo ako, kakaiba kasi para sa akin yong problem

update lang nakkuha ako diagram although hindi ka model pwedeng reference. yong 2 regulator na nabanggit tama voltage output. supply sa vertical ok din. hindi kaya posible na may tama vertical IC tapos nag protect sya kaya pati sound apektado? na try ko na rin kasi i shunt mga ecaps sa vertical section pero gnun pa rin. ano sa palagay nyo mga masters ? response naman dyan. value nga pala ng vertical AN15525A

lagyan mo din ng antenna may mga unit na nagmumute kapag walang narerecieve na station, sa vertical naman check mo po yung 100uf na capacitor papuntang pin3 pump up, tsaka yung filter capacitor sa pin2 tsaka yung 1000uF capacitor at 1 ohm resistor na nakaseries sa yoke paki check narin :)

nagka sound nga nung may antenna master nucleus, pero nag shunt ako mga ecaps wala pa rin normal naman voltage at ok rin mga resistors  kaya vertical IC talaga salarin. ang problem di available AN15525A dito. baka may alam kayo substitute sa ganito IC pa help na rin. +1 sa inyo master nucleus at master seph, salamat
