T50-CM3 Link Error Corrected by unplug/plug

[Gyster]

A couple weeks ago my throttle began to malfunction.  When I get into a plane (hot) the plane rpm goes up and down with no input to the physical throttle.  After a couple of instances of this, I tried unplugging the usb cable at the throttle end, and that corrects the problem.  When I look in the Virpil software, one or more axis show a link error fault.  Sometimes it's one throttle and flaps, or both throttles.  I've contacted support and they had me open it and check for any loose connections, but everything looks good inside.  This has become very consistent - 1st time I start the PC, the problem is present until I unplug/replug.  Then, it's good until I shut down the PC.  When I start it again, the problem returns.  Any ideas on what may be causing this?

To update this, I downgraded firmware per Virpil's request, and this worked for one reboot, but on second, the same problem returned.  They are thinking mainboard problem and are offering to send me a replacment or have me send the unit in for repair.  I haven't found any "how to" videos on this, but I asked if they have instructions or can provide guidance on the process.  When I opened it, I wasn't looking at the mainboard, so I don't know if it's easily accessible to replace.

I want to provide an update on this and provide a shout out to Virpil Controls for their really excellent customer support.  They sent me clear instructions with a  couple photos that made replacing the board super easy.  I received a mainboard from them this morning (a day earlier than expected).  The replacement was a breeze and within about 15 minutes had the new board installed and the throttle connected to my PC.  I started it, updated the firmware and set up my flap buttons.  I've restarted twice since then and they nailed the problem - no link error!  I've had this throttle for well over two years and the level of support I received was better than other products I've purchased that were still within warranty.  You really can't go wrong with them if you're in the market for a controller.
