English Amiga Board - View Single Post - Amiga 500+ (Rev 8A) - long black screen display duration before kickstart boot screen

Hi,

I had recently got an Amiga 500+ (rev 8A) with battery damage repaired - as per this thread:

http://eab.abime.net/showthread.php?t=98371

However, the boot up sequence is a bit strange and intermittent.

It will show an initial black (or is it dark grey?) screen with a strange red vertical streak on it:

The duration of this is a bit random and it can take a while - up to and beyond 10 seconds? (sorry, I haven't timed it) before it proceeds with the rest of the boot sequence and then showing the kickstart boot screen.

I assume this is not normal/common? My A500 (Rev 6A) does not behave like this - it goes to the boot screen in a reasonable/normal time (less than 5 seconds?).

Can somebody explain this behaviour (funny black screen, and long boot time) and to where I should look to try to diagnose and repair the issue.
