I have a Mac Classic that has recently stoped working. I'll start by describing what happened:
A received the Classic a few years ago and it has been working ok.
One thing that always caught my attention was that the startup bong has was very low (volume wise) and changing the volume had no real effect on the system. The volume was always low.
The last time it worked there was no startup bong the the computed booted OK (I wasn't wathing it boot, so I don't know if it took longer, or not, than usual).
The computer was used for cheking diskettes and copy some files for and from an external HD and it was left on for several hours.
After a while a noticed the the computer "hanged/crashed". I had a still image on screen but no response from the keyboard or mouse.
I tried to reboot the computed but I only got horizontal stripes.
I replaced the battery, cleaned the motherboard (with PCB cleaner) a replaced all of the following capacitors: C1, C2, C3, C4, C5, C6, C8 and C9.
I still only get perfect horizontal stripes.
What could be the problem now??
