The lock detect LED is not glowing after writing value from USB. What could be possible error?
Also PLL power LED (RED) is not ON how to debug?
I'm assuming you are powering the board via the USB interface, i.e. there is nothing connected to the banana connectors. If so, both switches should be pointing away from the banana connectors. The correct position of switches should turn on the power LED (D5). Does this help?
Thanks for the reply, its the zener in USB path i.e. gone bad..
