Power Supply Needed Repairing
Often when an power saw quits working the problem is with the power supply, not the unit itself. I have recently experienced this very thing with one of my most used power saws. When I went to turn the saw on, it began to start up but then quickly shut down. I double checked everything and it all seemed fine. I called my usual power saw repair shop and they said that was a sign that the power supply was bad. I sent them the saw and they confirmed that the power supply was indeed the problem. They fixed my power supply and I am now my power saw works fine again.
