Hi, new here, fairly new to electronics. I found a led tv on the tip and thought it's an opportunity to learn stuff. So far it seems the power board is no good. Some tiny diode seems no good as well as a mosfet. No doubt there are other components that are no good. Blown fuse. I find my skills and tools so far are not enough to be confident in being able to repair the board. Ive got a pc 12v psu to provide 5 and 12v and figured if I can wire 2 12 pc psu's together i can get 24v. On a site ( https://www.acopian.com/acopianPowerSupplies/entry.aspx?nsid=17 ) is a diagram. Is this applicable to a pc psu and if so how to know which wires are sense + and - ? Also is the 'reverse biased diode' enough name to know what diode to use.
