HTC Vive Wireless Adapter will not power on

Functioned well, until (about 3 months ago) it didn't. Now the Vive Wireless adapter may not turn on at random. Sometimes takes about 5 minutes after connecting the battery before finally powering on. Other times may not acknowledge power for days. :-( May or may not power back up if need arises to switch batteries for continued play. Or, may power up and shut off a few times before finally holding power to sync to my rig. No trauma to device. Changing USB cable(s) yields same result. Batteries fully charged. No issue with headset hardwired. Opening the adapter, noticed a pin hole to a button at the back of the device. (???) Prayed it was a reset... pushed the !&&* out of it of course. Once opened I found the right receiver micro-coax female connector totally missing from the end of the cable at the board. (?HUH... HOW?) Replaced with new MHF4 cable. Granted, this one does not quite mate as snug to the onboard male terminals. Nothing a little tape wouldn't secure. Suggestions for correct RF cable are appreciated. No other apparent sign of damage to boards or components. Though likely not, nor should that receiver cable be the culprit, power was restored after reassembly. Got a few weeks play out of it, albeit with some sporadic lag to powering on. Could live with that tho. At least it worked. Now... going on second day with no sign of power. My kid doesn't know yet... she's not gon like it. Much rather fix it than drop another $350 for another if I can help it. All great ideas and guidance, welcome!

Main problem I hear with the Original Vive Pro Wireless Adapter was overheating issues. Jerry Rigging a USB Powered Fan to the top of it helped me and a ton of others resolve that.

@siredslaughter Overheating is an issue for some… not an issue I’ve experienced tho! For me it was/is the MHF4 cable! Still haven’t found the correct one (nor have I looked into it further), but the MHF4 cable I swapped in 3 years ago (when I originally posted) has the adapter still functioning to this day. As stated, the replacement MHF4 cable female connector is just a bit too big to fit snug to the slightly smaller main board male receiver. If the adapter does not power on, reseating that connection (slapping the side with the wonky cable) fixes the problem!

@antagonist Sounds like the connector isn't fully connected if you have to hit the side of the box. Maybe check internally if the pins are actually long enough to reach the receivers inside the cable because that connection clearly isn't right.

As far as i can tell (correct me if i'm wrong) sounds like you can somewhat get the cable into the male replacement connector you have on the board. Sounds a bit risky but you might have to do a little bit of filing off that male connector so that it fits into the other half.

Let me know if that helps & hope you get this fixed :D
