I'm new here so, hello! :)Recently I discovered an Apple IIe in what it used to be my grandfathers basement.Cleaned it a bit hooked up everything and power it on, it didn't work very well, sometimes seemed to beep and display text another times just a green screen AKA no video:
Stayed on for like 5 minutes and then POOF smoke started to came of the thing!, quickly disconnected it. THE SMELL lasted for days!Checked the board and seamed fine. But a filter paper cap exploded inside the PSU; an ASTEC AA11040B. And replaced the filter with this one:
And output from PSU seems ok to me.
I proceeded to connect the PSU and nothing, no sound and the red LED on the motherboard doesn't turn on.
Later found out in another post in this forum that it could be the tantalium caps near the PSU connection. And got suggested to replace them, and... SUCCESS, now the board has power and the LED light turns on BUT we still have no video no beep. Btw cheked PSU under load and the reading looked ok (even better).
What is your suggestion on what should I do next? :( I'm running out of ideas.
Thank you so much in advance :)
