I have the same problem like you. Two Plugs are burnt. Did you manage it to replace them?
If you did, can you please send me where you bought the Plugs. Cant't find any reseller for female soldering PCIe power connectors.

Thank you very much

use a small screwdriver to dig out the melted plastic carefully then replace pcie cable, it should hash again. advise is to set it to power save mode and gets u about 960ghs or so. improve cooling too.

Thank you for the reply.
I have to change them, they are damaged. After a long search I found the right ones (maybe).

You have to google for 1586037-6

I am parting out my miners -- anyone interested in CCD modules? 

I'm in the US, so international shipping may be prohibitive

I didn't see anything like that but I did notice the tree wires coming from the outlet cable to the power supplies were in different orders.( may they swapped in a crummy power supplies and hooked it up wrong.)
What colors are your guys according to top to bottom.
Yellow black red
Then
Red yellow black
What you guys have?( just look at the back through the holes

spme pic will help out ! post some pix n i'll get back to you here.

no beeps on ccd's

wrongly wired = easy to blow things up

check the board across the blades, possibly pins not connected properly or bent (common)

switch to correct voltage 110/220V at psu

the ribbon cable from control board to the red connector board, that comes out easily too

sdcard too is it properly seated ?

does the rpi lit up at all ? anything on display ?

etc etc

Just a wild guess, do you see any 110/220V switch on the power supply, set to 220 (if you're using 110)?

whats up with my rig?
I just received 2 rig units with 4 boards a piece and i cont power them up.
I saw that the ones he did send me (via skype) were working at some point. whats going on?
He sent me everything but the power cable so i bought this one

their is no fan noise no beeps not even the tiny green light on the back?

Am i missing something or is their a power switch im blind to ?

Ok I finally managed to get physically to my miner.. I opened it and everything looked fine by visual inspection. No melted stuff, everything in place.
So I started experimenting, tested one module at a time, moved them around in different positions on the backplane and tested all of the PSU power connectors. I concuded that one of the modules is faulty. I removed it from the CCD.
Will contact bitmine and see if they can offer a replacement.

Also the temperature sensor still does not show up on the web interface. I also noticed that on the lcd screen, when I power up the miner it stays on the "Loading minerosd.." message and it does not display the hashrate, IP and temperature. This looks a software problem to me though.

Well problem is that I have the miner in a remote location (with free electricity) and I only have web/SSH access to it. Hope nothing melted.. Any way to check through linux?

gotta be physical ! haha . . . i would power down the miner & see to believe.

check your pcie cable/power supply or connections, pcie could have melted/broken. best to run @ power safe light imo. very low hw erros, less heat, good power to ghs ration too. well thats just me.

I had a 3-module 600gh/ CCD and I got another module 1 month ago so I went up to 800gh/s. I installed it and the desk was running fine at 800 - 850gh/s @ turbo moderate. But today suddenly one of the modules stopped working (can't tell if it is the new one or one of the other old ones). The "missing" module simply does not appear in the dashboard webpage. I have tried the following things:
-rebooting
-killing cgminer process through ssh and restarting cgminer manually, cgminer itself displays only 3 modules
-selecting all of the power modes (from power save ultra through turbo ultra)

None worked.
I also don't get the temperature on the dashboard any more.
Any ideas?

Today, it's a good day  Grin - I'm back in action.
What I did:

Thanks to the information by Soros Shorts and wolke, I checked the PSU-cables.
There are many differences regarding the connector-settings of ANTEC and the LEPA.
So the failure was to use the ANTEC cable-management cables with the LEPA- so i shot through the PS-ON Pin to much Power.
What happened:
1. The Raspberry PI died an heroic death, because it got more than 5V and plenty more current.
2. Like on the picture of the last post, some parts and connections of the PCB died.
So I tested again and figured out, that the connection between the socket of the PS-ON-pin was broken.
I solved this with an quick and dirty modification:
http://i59.tinypic.com/2daatki.jpg
After some more tries, I figured out that the PS did not start. So the PS-ON circuit was probably damaged.
I fixed this with an paperclip between GND and PS-ON as bypass.
The new spare Raspberry PI started again!!! (Was glad to own one!!)

After installing and connecting all together and do a test-run I was very very very lucky:
Mining again, all units working  Grin Grin Grin

BUT I really think that the overheat-shutdown doesn't work regarding to the damages (I don't really care).

Thanks for your help, maybe this helps some one who made the same (facepalm) mistake like I did.
