Ganeshan, It is best not to assume, or hope things just work when powering a pcb externally. Be sure that you understand the datasheet requirements and limitations. That being said, you can use a multimeter to check for shorts or bad components. The Schematics should be available in C2000Ware including the BOM. find and replace any bad component. If you are unable to do so, the next thing to do is to purchase a new pcb. Thanks, Mark
