I am troubleshooting a SMPS for a projection tv and am not too sure on
what the load should be. The prints only mention voltages, no loads. The schematics show that a +130vdc line is connected to a photocoupler, so im assuming this is the line that is used for feedback regulation, and therefore the one that needs the load. I have looked all over google for "dummy load" and cant really find a good site to help me out on this. Any ideas Sam? The sticker on the outside of the smps says 120v 150w if that helps. |
