My father asked me a question recently for which I had no good answer. Here was the problem he described:
"we had a thunderstorm and before I got to my computer to shut it down a lightening bolt killed my electricity for just a second. Everything came back on except the monitor on my computer. I have tried to restart it several times a day since then but it always remained totally dead, no power, nothing. Today it magically came on! Everything is back to normal after four and a half days!"
I can not think of anything that would have lasted that long. My best guess would have been blown fuse -- made invalid by fact that it works again by itself -- or temporary condition caused by an overtemp (ie. blown diode or cap -- wouldn't have resolved itself in days --- hours at best if resolvable). Anyone have a possible explanation. I live in a different state so I can't do any actual analysis -- just at a loss for possibilities. Thanks.
