Hello Fellows!
I got a IIsi from ebay. It shows a blue screen on a 13" Apple High Resolution monitor when powers on.
After some frustaration, I added a new PRAM battery and replaced all 47uF caps, but not the big caps yet. But the result is all the same except the PSU can be switched off by the power button (previously, it refused to turn off unless unplug.)
Another strange thing is the RAM slots:
<a> if the 2 slots near to the PRAM battery is filled with RAM, this boots with a single chime + blue screen
<b> if the other 2 slots or all 4 slots are filled with RAM, this boots with a single chime followed by a death of chime melody + blue screen
To avoid the death of chime in <b>, right now I put only RAMs on the 2 slots near the battery, but the blue screen problem remains as in (a)
Its hard disk is good because I tried it on another Mac.
Some suggestions would be much appreciated as I run of of tricks.
Best!
