Hello all,
I am a proud owner of an Apple Lisa 2/Macintosh XL since 2 months. Before turning it on for the first time, I replaced ALL the capacitors.
Now I have the following problems:
1. no video, CRT completely dark. I got a videoboard sent to me by another collector, with this it works fine.
Now the question is what is defective in my videoboard? The caps are all new. What components are known to fail?
I unfortunately do not have an oscilloscope...
2. the 25MB SUN Remarketing HDD does not spin and flashes 3x slow, 3x fast. I have tried to turn this on manually, still it will not start. I have replaced the capacitors on the HDD board and the controller board. However, I know that old hard drive and especially MiniScribe are very likely to fail and can not be repaired.
3. a ProFile 5MB was also included. The self test completes without any problems. But as soon as I connect a parallel cable the LED is on and the check does not start.
I bought this cable from Amazon:
Thanks in advance for the support
