New to Arduino. Have an Arduino UNO (Funduino). The Green PWR led does not come on when I connect to the PC. It is not the USB cable. Do I have to buy a new board or is there a fix?
Have you tried using an external power supply via the input jack?
Have you tried measuring the 5v supply?
What testing have you done?

I have used external 9v battery.Same result. Only reaction is a red LED blinking.
There is 5v on the board 5vpin. Arduino does not come up as a device on the PC.
Is this different from what you get with USB power? You did not mention the red LED in OP.
What speed is the LED flashing? Approx 1/2 second? This may be the "blink" program running.

The Red led is flashing with a frequency about 1sec. The 5vpin on the board is giving 4.99v and the USB cable power reads 5.01v
