Certainly measuring the voltage of the supply should show that either it is functioning or not. But please be very careful to not cause any short circuiting to other places while measuring. In other threads probing errors while measuring have caused additional failures.
Unfortunately, on most occasions, the component that is burned is not the part that caused the problem, but rather the unfortunate victim of an excess power surge caused by some other part failing. The result being that replacing only the burned part will only result in a second burned part. So additional analysis is required to learn the actual cause of the failure. Switching power supplies are a very challenging product to service, as a result.
