I've obtained (from my son) an unwanted TF101 which had a broken audio out socket.  I bought a new audio IO / HDMI board (US$20 ex Ebay) and fitted it, solving that problem.
However, the GPS doesn't work.  I'm sure that GPS did work on this tablet (at least it did before it was updated to android 4.03), but now it won't find any satellites at all, even after sitting outdoors for an hour (in contrast, my cheap Huawei android phone manages to find satellites even sitting here typing this - under an iron roof).  I recall that when it was new - it took a long time to get an initial fix, but that was in the order of 10 or 15 minutes, and it could "see" satellites pretty fast.
I've done a factory reset - and also a manual reload of factory firmware, but no go.  When I had it apart, I noted that the Wifi and GPS share an antenna board, wifi and bluetooth work fine, nothing touched in that area of the device.  GPS is enabled in settings, as well as A-GPS and google location services. 
Note that the TF101 doesn't (or shouldn't) suffer the GPS problems (antenna under a metal case) as the Transformer "Prime" model.
Using GPS Essentials to show satellites / lock status.  Makes no apparent difference if wifi and/or bluetooth is enabled or not (though wifi should enable faster fix by d/l A-GPS data, if I understand correctly)
Any suggestions as to what else I can try to get GPS working?

Hmm - problem seems to be solved, but I had to leave GPS on with tablet next to a window overnight, on power with screen-off timeout disabled. It could then "see" one satellite when I checked this morning. I've put it outside, and after waiting for 30 minutes, it now "sees" many satellites and gets a fix quite quickly. This was with wifi off which I thought meant that A-GPS data couldn't be d/l, but with wifi enabled on previous attempts it seemed to make no difference (but I didn't leave it for as long as 12 hours).
