Hi,
I am an engineer and like electronics and starting to try and fix things. I have power supply board from a tv and the 5v line is actually 13v so im trying to find why. I have traced it back to the transformer that goes from primary to secondary circuit. There are two resistors that have 13v each side of them. Then theres a capacitor linking them to the transformer. But there is no voltage at the transformer i cant work that out. Its the only place the power can be coming from i think, if anyone can work it out from the photo would be much appretiated.
Thanks
In the bottom photo the yellow circle in the transformer, the red circle is the blue capacitor connecting across, The two smaller blue circles are the end of the resistors that have 13 volts voth ends. And the big blue circle is the part that is 13v should be all 5.
