Hi, I thank you, I replaced all the electrolytics on the primary , and since I found the diodes bridge so much to remove my doubt, then I managed to find on another circuit I also have resistance from 3.3ohm 10 w, but just current the resistance is jumped immediately, I tried to measure the heads of R601 and there are 240V, I can't understand, there is a short circuit somewhere that puts R601 in parallel to tension of network . Whether it's all the fault of the str, the strange and that only Zener D611 jumped at the beginning.
This scheme should be more detailed
