Hi there,

I picketed up an LC 475. The first thing I did was swap the battery with a new one I had just purchased brand new :)

I power it on, it chimes ok, the external display shows the grey screen on and mouse pointer for a few seconds. Then, the video starts to roll to an extent that I can't make it out. I think it is still sitting at that screen and not trying to boot further. No other error chimes or disk activity is heard. I tried booting it with a known-good internal SCSI drive w/7.5.3 that boots my IIci, Centris and SE fine. Same time happens attempting to boost from an external Zip drive (yes, I have 2 that work!). 

It's almost if, after a few seconds of being on, something is overheating. Do I need to to recap? System board cleaning? Is it a lost cause?

if component level repair is needed, I will probably hire one of the pros on this site - I know my limits!
