LED doesn't light up
So, today I finally received my new PSU and after installing it, my newly bought STE works (I think) as it should. I could format a floppy and save the desktop config to it, and it boots from my ST4SD. I can also start games from it. There are just a few things that bother me. one of which is that the power led to the left of the keyboard doesn't light up. Does this indicate a bigger problem? And if not, can I replace it?

Re: LED doesn't light up
What I've seen happen with the power LEDs is for the LED to be pushed in and it damages the connection on the PCB as the LED is just soldered in, should be repairable as likely just a broken connection.Reluctant16bitter wrote: 19 Aug 2025 18:06 So, today I finally received my new PSU and after installing it, my newly bought STE works (I think) as it should.

Be aware that there are rubber domes under the keys (In most keyboards) and not all spots are filled with them. There are reference images here: Keyboard Reference
