Schneider Electric M258 NO LITES

[randomando 0]

I have a Schneider Electric M258 with no lights on the CPU. I have verified that I have power going to it. I also have a spare unit that I removed from another location because I only got red lights on that one. I put this one it and I did get lights although they were all still red. I did that to verify that I did have power going to the CPU. Is there something that you know that I can check? Does anyone repair this model? I understand that it is now obsolete.

 

Thanks all,

If it has no lights at all, likely something has failed internally.  Most PLCs have at least a power LED that should be on.  Not familiar with that unit, but doesn't sound good...
