Macintosh Plus Trouble shooting.
I have had trouble with this machine a lot but i need a little help.
I noticed some broken solder mask and broken traces but i know those traces are not important because they go to the battery compartment. But i need to know why wont it start. When i turn it on it makes a Hi voltage sound. Like a Click-THUMP sound and then nothing happens. Sometimes it does it over and over again or just once.
When i power it off after the sound/s then power it on again the sound does not happen and there is no sign of life!
SYMPTOMS: A HI Voltage Click-thump sound , no startup BONG, No video or sound , and a black screen.
Also can someone give me the list of capacitors on the analog board?
These are some broken traces
NOTE: not my image!
Are you sure they are broken and not the over-cover just isn't scratched. Did you check the continuity? Can you post your board so we can so how it looks do both sides and as detailed as you can.
I can get another computer for the same price as it would cost to fix this one and also that would give me a machine to test the analog and logic board on.
