Pambihira case ito. Common na kasi ung naninira ng HOT pero ito flyback ang sinisibak.
Anu ba TS ung flyback,replacement? di kay me factory defect. Ung unang flyback na nasunog un pa ung luma na orig?

mga limang flyback pa sis at sure makukuha mo na ang salarin dyan. ;D ;D.. try mo muna sis yung suggestion sa taas. tapos monitor ang B+ at ang Base voltages ng Hot habang naka ON ang TV set.

uncommon tong problem mo a..monitor mo B+ ng HOT and fbt around 125-130volts, after 5 mins unplug the set and pakiramdaman mo baka overheat na FBt or nangangamoy..wag lng masyadong tagalan ang pag-test kasi wala ka pang nakitang defective parts..

btw.. baklasin mo DEf.Yoke baka may trace ng sunog ang HOr.windings.. :)
