I recently bought an LC 475. At first it did that weird repeated pipping sound that I associate with power supply issues - so I recapped the power supply and motherboard, and apart from some issues with the hard drive eventually got it working. I had it booting consistently from an internal BlueSCSI V2 whilst also having a BlueSCSI V1 connected externally. I put a new 32 MB SIMM as well as upgraded the VRAM to 1MB. All was good - except it took a long time before any video output would appear - I assumed this was the time it was taking to test the large amount of memory.
However, a week later and I power it on without changing anything - I get a chime, but video never appears. However, pressing Apple-Control-Reset does cause it to re-boot (startup chime sounds). It has a new battery. I've tested by removing the RAM and the extra VRAM and this didn't make any difference (it has onboard RAM and VRAM).
Any ideas how to investigate this further?
