B&k EX4420

Hello all. Does anybody know if they have had issues with the power button led LED not illuminating on their b&k amps. The amp works fine but the power button led is out. It is a small orange square/rectangular one. Is it easy to replace?. I took the front panel off to take a look at it but it looks like it is soldered in. I am also not able to find the replacement for it. I am sure there is place where it is available but I am not able to find it. Any help would be appreciated. Thanks,.
