I took other measurements, I'll have to find something wrong ��, so, on + of C824, according to the diagram, 24 V should be coming, but I find 16.3 V. Then, continuing with D807 in parallel with C820, I find 3.8 V. I tested D807 disassembled and the multimeter is fine. If I read the diagram correctly, D807 and C820 go to pin 9 of the flyback .
The 24 V line that goes to C824 comes from pin 7 of this thing that I don't know what it is, I have to locate it on the board.
