I have a 1st Gen Time Capsule 1tb. It turns on, boots up and turns green for 5-10 mins, but then turns solid orange and then blinks orange. I have removed the hard drive and replaced the power supply . . . still the same problem. Suggestions?

Question

I purchased a used 1st Gen Time Capsule with a 1 tb hard drive.
When I plugged it in and did the initial setup, it worked fine, but gave me a hard drive error.  A few minutes later the green light turned solid orange, then blinking orange, then the status light went off.  The lights in back stayed on. 
I removed the hard drive and rebooted, it turned green for 5-10 minutes then reverted back to a solid orange, blinking orange, then went off.
Next I purchased a remanufactured internal power supply, and installed it (without the hard drive in).  It turned green almost immediately.  After about 15-20 minutes, I decided to try to install the hard drive again, booted it up, and tried to erase the hard drive with was working properly according to the software.  It stopped erasing the disc after about 20 minutes and turned solid orange again, then blinking, then no status light  (but back lights were still lit).
I'm a bit flabbergasted at this point, any suggestions on what to do next?  I think i've pretty much replaced everything except the logic board, but can't seem to find any information on the symptoms of a logic board malfunction. 
Thanks!!!!!!!

A Gen3 is identical board to a Gen4 although they have some differences in firmware and wireless card was updated on every model.. but a Gen3 is substantially faster than Gen1, Gen2 which also have identical boards.
You can with careful shopping get a Gen3 pretty cheap.
Most use a delta power supply which I think is a lot better than the flextronics used in most Gen1/2
You can sell back the parts to ebay.. people still would buy the power supply etc. Even just the case can be useful to a repairer.
But if the board is gone.. it is hard to repair.. not impossible.. but hard.
Gen 3 and Gen 4 are not without faults.

I have fixed it a different way.. by using the small converters you can buy in bulk from ebay for $1 each.. KIS3R33 .. they produce 3.3V at 2A peaking at 3A.. amazing.. I keep using them to replace onboard power converters by removing the inductor and simply power directly.. the end result has worked great. You can simply change the resistors around and get any output from 1v to 20v depending on input.
Is it worth doing it .. no of course not.. it will waste many more hours than $50 is worth.. but it is kind of fun that you can actually make things work again.
Here is a pic of the Gen 3 totally powered by me. All onboard power removed.
This was to track down the fault in the Gen3.. but I am kind of pleased that it ended up neat enough and reliable enough to work for more than a year.. the Gen3 still serves as a way to get Netflix via network for a friend running 24/7.
The units supply (from left to right)
1v, 1.1v, 3.3v, 5v, 1.8v
It is feed by 12v supply which is also directly connected to the hard disk.
So it is possible to fix.. !! Only got to be a bit crazy.
