If you connect the printer to your computer with a USB cable, operating system of your choice, the printer is invisible to the computer. The RJ45 (network) port is dead, the USB port is dead. Plugging it back in does NOT 'wake' the machine up, it does nothing. There is no sound, and you can only get the thing to turn off by unplugging it. Why is it so hard for people to understand the issue here? The problem I have had with my Samsung C410W (and from Internet searches I've done many others have had the identical problem) is that you press the power switch, the blue light around it comes on, and that's it. I am not delighted by that prospect but I may do that and be done with it. If you would have to have a repair shop do the work I'm certain you'd be wiser to take the printer to the electronics recycler and dispose of it. However, you're probably looking at 100 to maybe 150 (or more) dollars for the two circuit boards and so you have to decide whether it makes sense to repair it.

If you are willing and able to tear apart the printer and do the work yourself you can find (again through searches) replacements for the two main boards in the printer, and they would not be difficult to replace once you figure out the magic of taking the printer apart. Your printer like mine clearly has a circuit board failure. There are a few things that might revive it like making sure the fuser temperature safety hasn't been thrown (do an Internet search on this I did that but it didn't help me).

I have the same printer and it turns on, but nothing beyond that and it can only be turned off by unplugging (as with the OP).
