Hi there. Frost of all I'm a noob when it comes to electronic repairs. My knowledge is very limited. I have TV power supply. Which is not outputting any voltage to main board. But that's not a point I have rectifier diode N4007 and on start it has 236V AC and on the other side just 4V DC, so rest of main caps has just 4V, is it faulty? I test it and it seems to be ok one side is closed other has 0.56v. As I said I don't really know how them things work like. What I read this diode converting AC to DC. But is it fine when 236 DC going to 4v DC?
