[comp.sys.mac.hardware] MacPlus screen on the Blink

jkirsh@contact.uucp (Joel Kirsh) (03/10/91)

My almost-two-year-old Mac plus has recently developed intermittent "black-
outs" (maybe I should be crossposting to sci.med? ;-) )

The entire display goes black, but returns with just a slight tap of the
casing.  Anyone seen this before?  Is it my entire display that's trashed,
or just a flakey connection here or there?  Am I about to be electrocuted
by an improperly connected flyback transformer?

Any and all advice welcome.

Most likely, the constant heating and cooling of the power supply has caused
the solder joints on the analog board on the connector that conects the
alalog board to the logic board to crack.

If you are daring, open up the Mac and take a look.  The same thing happened
to me, I resoldered some joints and it works fine.
