Problem with an Antminer S5 blade - Help please

[esawyja]

Hi all,
Can someone provide me with some troubleshooting tips on a S5 blade V1.91 2015-03-28 (With Mini Heatsinks)?
The fault moves with the board, IE I have moved the cables around, physically moved the board around to the other side of the controller and re-pasted the thermal grease on the ASICs.
There seems to be a RED LED on the blade that works, I don't see it lit on the faulty board. The web interface displays ----- or xxxxx, I've even moved the cables to the inner ports on the controller board, all this seems to do it to change from chain 0 to 1,
Are there any Voltage regulators on the blade maybe, something I can check, or voltage readings on the test pads?
Any suggestions please
Regards
