Two blinks indicate OVP over current proction. Check for abnormal +B, FBT & related circuit.Shifting of picture indicates defective AFC.

Thanks Gore, i have checked B+, fbt and soldered all pcb. since i don't have
the schematic, to check AFC is quite diffilcult, searching in the net is also not fruitful at present. pls help me with schematic or guide to available site.
thanks again.

hi Gore,
            thanks for your help. i find the fault, it has been the B+ resistor R615 , 1.2ohm goes high ohm. which switches on the ocp transistor and
shut down AFC first to shift the picture to left side before shutting down.
Thanks for your help.
