There may be a cable that became loose during shipping; if you are comfortable you can try to take it apart and look for any obvious signs of trouble Disassembly / Repair - SparkFun RTK Product Manual
If nothing comes from that the next step will be an RMA Returns
Hi, Thanks. I re-seated the ribbon cables to the display board and it worked for a while then same fault. Left for a while it started working again. I really need two units for an upcoming project. Considering buying a third unit as a backup if I need to send this one back.
If that’d make your situation easier I’d say go for it (and we’ll get the problem unit replaced, repaired, or refunded…whichever you’d prefer)
Was it purchased from us? If so head over to Returns (contact vendor if purchased elsewhere) and we’ll get ya squared away
Thanks. I’ve ordered another unit. It’s through digikey so I suppose I will need to get in touch with them. The fault hasn’t re-appeared, however. It maybe difficult to diagnose.
Thanks again.

Hi, the unit came to life for a while, so as I was in the middle of a project, left the return. The issue has come back, but now Digikey won’t accept return. Is there a way to go through Sparkfun direct?
Yes, please start a return and reference this thread, and we’ll get it taken care of. Please include when you ordered from DigiKey (in your return comments) so that we can assign this defective device to a batch of devices.
Thanks for your support. I’m back out in the field for three weeks so can’t action this until I return. The unit has been acting as a temporary base and amazingly has worked flawlessly for the last five days. I’m struggling to diagnose the problem when it is intermittent. It seems to be associated with switching on or off. If it’s up and running, it will happily work all day.
Switching off requires an extra long hold if it’s been on for hours. Does that make sense? If you give up to soon, you don’t get the ‘switching off’ message and the display goes blank. Software? … Just a thought.
I suspect the display overlay (the sticker on the front) is failing over time so, while the unit is working just fine, the on/off button may be failing. The best way to diagnose this is to plug in a USB cable and watch the Device manager.
If you press the POWER button for a few seconds and see a couple COM ports appear under the Device manager but the display does not illuminate then you have a bad display.
If you press the POWER button for a few seconds and don’t see any COM ports, and the display does not illuminate, then perhaps the external button has failed. You can prove this by opening the unit and pressing the internal power button. Docs for this are here. If the internal button works, but the external button doesn’t, then we’ve isolated the problem to the external overlay/sticker.
The ribbon connector has ~250 microns of horizontal play. From what you describe, I’d bet that removing the external overlay/sticker’s ribbon and re-inserting it into the display board may clear up the issue.
Either way, let us know and we’ll get the unit fixed up for you.
