SAMSUNG ZOOM TOTALY DEAD


This time really make perforated bag (not a word Rano Karno, hehehe). Samsung zoom vision CS1439Z, owned mas Nardi, Sapen, Manisrenggo. Under these conditions the total dead, in a voice quite loud ringing on the SMPS power supply.
Tv is using IC MCU SZM-139, IC Chroma (1CHIP) m52777SP

After opening the lid back, check-type TR HOT SD1771 in a state short, I immediately replace with new.
Tried ringing sound now turn away, ....... indicator light is a flame. At the start there are changes to the LEDs, but no any reaction on the screen and sound, what's this?

Check voltage on the basis of TR HOT absent.
Note: if I use led to know it, mounted on base with ground, the position of TR HOT removed. All TR the drivers before the normal transformer, the other components around the IC Chroma (1CHIP) jg not find any discrepancy. Finally i try to replace the IC m52777sp and can turn on the ignition, turn off ... try to hold the heat sink gets very hot TR Horizontal teryata not normal, its allegedly defective FBT nih. Try to replace the former but ok FBT type FCK14A033.

Try again ........ can flame but why there are no broadcasts that stuck, try changing the voltage to normal tuner tuner type TELE 1-002A.
Ooo ...... means that it is true tunernya damaged.
But why not focus the image, try cleaning the inside of the socket CRTnya (focus). Images can focus again. Alhamdulillah finally finished as well. In total it cost so much, but who have not said anything, because TV is giving parents.
good luck...
