Can you use an oscilloscope to check if the problem lies on that the MCU doesn't output high voltage or the LED is broken?

It was working properly earlier and now I can only see the LED blinking on the Captivate BSWP programmer. In the Captivate Design center tool, MCU seems to be connected but the LED indication is not up now .

The LED1 will gets turn on sometimes but no touch is detected at the time and LED2 and LED3 are not getting turned on.

I know, can you change the code directly to light these 3 LEDs? And then use an oscilloscpe or a multimeter to detection the GPIO output.
