This is a Desktop unit but thanks none the less for the advice. I will take a closer look at the video connection though. I don't assume she is booting to anything. I have attempted to boot from the known working CF HD and from an emulated workbench floppy. When i boot with the latter i can see the disk being read via the read light. We can assume it is booting up but I don't know for sure. such a noob at tshooting this things! lol I do not have another accelarator card to try at the moment. I had checked the voltages on the power supply and they checked out ok all around. I don't recall inspecting those connections though, so will do so. Ill check back in here in a day or so with any news. Thanks again.
You might double check the jumpers and make sure all is ok still, physically move them to make sure you have contact. Have you hotplugged anything in? video,mouse etc/ i seem to think a dead cia can cause a black screen but thats just a guess. can you hold the mouse buttons down on power up and get tothe early startup by chance? what monitor do you use?
The caps light you mention suggests the cpu board however. was the A3640 040 board recapped also? its not uncommon for cap leaks to eat a trace running near or under the capacitors.
I saw your post on EAB,you didnt mention it had a indivision here. more than likely its came loose,isnt making good contact or its popped a solder joint on the video chip where its soldered to the motherboard. Check it with a 15khz monitor on the native port.
