AKIRA flyback modification: BSC 25-1055

had confused the TV AKIRA get 14 "of his damaged FBT, which bertype: BSC25-1055buatan KONKA.Karena the best mechanic in Jakarta especially allergic to artificial konka FBT, due to its spare parts are hard to find.
Luckily I 2000.selalu since records and records pin layout of the legs of each flyback all kinds of type-been entered in the ZIC WORKSHOP (our garage).
After I observe apparently no type equation of this type, then the only solution is to modify the flyback-like arrangement of legs.
Of the many, my choice fell on the type of flyback Goldstar 154-177B or 154-064P (the second type is identical)


The order of the pins bsc25 FBT-1155 is as follows:
1.PIN1 = Coll (H-OUT)
2.PIN2 = B + (VCC)
3.PIN3 = 180V (VIDEO OUT VCC)
4.PIN4 = GROUND
5.PIN5, PIN6 = N.C (TAKTERPAKAI)
6.PIN7 = ABL
7.PIN8 = Heater
8.PIN9 = N.C (TAKTERPAKAI)
9.PIN10 = AFC
While the sequence of FBT 154-177B or 154-064P is
as follows:
1.PIN1. = Coll (H-OUT)
2.PIN2. = B + (VCC)
3.PIN3 = 180V (VIDEO OUT VCC)
4.PIN4 = GROUND
5.PIN5 = 15V
6.PIN6 = 24V
7.PIN7 = 40V
8.PIN8 = ABL
9.PIN9 = Heater
10.PIN10 = AFC.


The trick is to modify it as follows;
After the original FBT (BSC25-1055) has been released, disconnect the line by cutting the PCB track (using the cutter) that led to the hole (pin) 7 and pin8, while pin9 is free (NC). Enter the FBT-154 FBT 177b into the socket. after a certain point and pin8 pin7 been disconnected, jumper (connect) pins (legs) 9 kejalur bound pin8.dan pins (legs) 8 kejalur which also connect to the external pins that pin7.setelah ABL from fbt154-177b combine it with pins ( feet) 8.
flyback ready for action, and good, not an iota of difference with the original appearance, such as image width and height of images, as well as temperature rise TR. Hor-out is also very normal.
TV sets were ready for action .. JUST DO IT.
