[QUOTE="harm lok, post: 1088306, member: 415123"] Thanks for your quick responses. The diagram and layout off the power supply of my SR8700 is different from the LT8700 schematics. Although some parts of the circuit seem to be the same. The rectified voltage of 240 v is present but the power supply does not switch. I have enclosed some photo's from the power supply board and the overview of the SR8700. Unfortunately the NTC (also RT1 on this board) is not defect. So i have to search further. There is a spot at the inner top plate above the 2000 uF capacitor so i wil solder it en test it separately. If someone recognize the board and maybe some clues please respond.
