   Hi All,   
      
   I have a small question for the community.   
   Not long ago I picked up a nice looking TRS-80 computer with a matching   
   TRS-80 Video Display, modem and cassette player/recorder. Display had been   
   given away for free immediately, because I simply do not have a place for it.   
   And I am more interested in computer itself.   
   Now, getting closer to the question I wanted to ask, this computer has a   
   problem. Before plugging in the original PSU, I checked the output voltages,   
   and those seemed to be ok. But when I try to turn on the computer, the power   
   LED turns on for a second, then something clicks inside the computer, and   
   LED turns off. Second later this cycle repeats.   
   I haven't opened the case yet, but decided to ask the community first: what   
   could be causing this problem? Clicking sounds like some kind of relay is   
   switching off, but I am pretty sure, there should be no mechanical relays   
   inside. Most probably something is dead/shorted, but why would it produce a   
   sound then?   
   Please explain what that could be, so I would start looking at it first after   
   I open the case.   
      
   Thank you.
