Are the keyboard lights actually flashing or do you simply get a random combination coming on at each power up?
I've recently repaired one of my A4s which had the latter issue - I'd get none, some or all of the lights coming on at power up with no other signs of life.
Replacing the electrolytic caps and then giving the board a good clean with distilled water and IPA did the trick. After a good dry out, it came back to life and has worked ever since - no issues or freezes.
I'd bite the bullet and replace the caps to see if that resolves the problem. Don't forget to wash the board to remove any gunk too.
