Any suggestions? Thanks!

Well you can add me to the list of ever growing users that are having the PS problems with their TC!!! I'm going to hit up Apple and see what they will do for me... Replacement would be great, but I'm not holding my breath

My advice: try and get a new one from Apple before you do anything, and do not do the fan mod, it does not completely prevent the failure.... and then one is out of luck with regards to Applecare.

Screwed too today. Second one...my replacement died and Apple wouldn't replace as they use original purchase date as benchmark.....pretty angry
How long did the replacement last?
You can fix it with a replacement power supply or better yet using an external power supply like the cisco.. described here.

The rest of it will be fine .. well in 99% of cases it is.
Just the power supply and somehow the replacement ones never seem as solid as the original which was pretty flakey to begin with. The approach to powering it internally with cooling is just wrong headed, directed by interior decorators with over sensitive hearing. You can build it without active cooling by using an external power supply. Or using an aluminium flutted top case with external antennas.. but not the way that Apple did it. Thick plastic and torturous path to convective cooling.
Hello Stacyparrish,
All the TCs to date have a basic design flaw. They overheat. The flaw would cost too much money to design it out of the product, so Apple have 'beefed up' some aspects of the innards of the TC but not quite enough to make the product 'solid'.
To recap (I have done this before):
1. There is NO AIR INLET hole for the in-built fan.
2. The in-built FAN POINTS THE WRONG WAY.
3. Until the most recent model; the FAN IS NOT TURNED ON.
The fan now runs proportional to the internal temperature probe that is stuck onto the side of the internal hard drive. This is a seemingly sensible place to put the probe but the hard drive does not generate the bulk of the internal heat; the PSU does. On a warm day the internal temperature of some key components, in the PSU, goes beyond the recommended maximum.
The PSU has a plastic wrap to screen and insulate it from other components. It is open at both ends and air can be blown through it.
The fan, presently pointing the wrong way, can be made to blow air through the PSU case and when this is done the whole case temperature drops by some 10 to 11 degrees C. When this is done the excessive heat is removed and the whole TC settles into a reliable mode of operation.
Putting in a PSU, of different make that can withstand the high temperatures, stops the weakest link being the power supply. However, the 'fault' then moves to the next weakest link in the chain, probably the voltage regulators on the main board, which ar surface mounted and far more difficult to repair.
Putting in a 'Green Drive' that will take slightly less current and therefore produced slightly less heat build up merely forestalls the inevitable failure of the TC, because IT RUNS TOO HOT.
Ray Haverfield (Lapastenague) was at the vanguard of TC fault finding and prefers installing an external PSU. This has many technical advantages, not least removing at a stroke the major source of the damaging heat. He and many other 'fixers' prefer this option. See his wonderful site on:
http://sites.google.com/site/lapastenague/a-deconstruction-of-routers-and-modems /apple-time-capsule-repair
I, on the other hand, created a far steeper and rocky path for myself by trying to fix 'the design' of the TC, which is where I am now. I have probably optimised the present set-up but need to work on the fan speed control rather than permanently at half speed.
I have asked Apple for comments on what I do, on this and via their feedback option. I have done this more than once.
A deafening silence so far.

After the number of places you stuck your probes, if it wasn't dead it is now. And since you survived it.. be thankful and move on.
You have an excellent set of logic board plugs.. soldered into the now useless power supply. Unsolder them.. and solder wires to them.. so you can connect the new power supply.
There is the full screed with pics even to show you how to convert a Cisco power supply .. which unlike the Apple one could go another 20years.. although ironically made by delta..

This can cost you $20US plus posts.. there are heaps of them on ebay in USA.. and HK.. but I find the HK ones a bit rough..
Carlo, your TC is probably dead. In Gen 1 Time Capsules the power supply often fails. If you call Apple Customer Relations they might replace it. I had the same problem as you and Apple has replaced mine even though the replacement program ended in Aug 2011.
