- I had exactly the same kind of symptoms with my plus; I tried cooling it
- (it helped a little), pushing and pulling Mac around my table helped a
- lot and in the end I used a little stick, that didn't conduct electricity,
- to pend my analog board (it helped a while).
- Then when the screen started to flash again, I got tired, and disassembled
- the machine and examined the analog board very carefully, and soldered
- some connections that didn't look okay.
- It helped. Since then my Mac hasn't had the same proble again (and they
- all lived happily ever after... :-) )
- I believe that either the heat that Macintosh Plus generates inside it's
- cover has something to do with the problem or then it is a manufacturers
- fault.
-
- If you need any more advice (I'm not sure I can help you anymore, but still)
- my e-mail address should be in the bottom of this text, but if not, it is:
- jrosvall@lut.fi

- Try not to loose your mind, I almost did ;-)
