I bought a Thrustmaster T500 used from a member here and I got it several weeks ago. It worked fantastic and it was a good deal. I started a ticket with Thrustmaster to have the F1 wheel buttons and the base fan replaced. Thursday night I use the wheel without any issues at all. Friday night I fired up the wheel and nothing happened. The only light was in the power brick but otherwise there was no trace of the wheel in the Controller CP and the TM CP. I checked all my connections, plugged the power on another outlet and tested it first, changed the USB port and so on: nothing., Then, as I was about to pack it up and remove it from my desk, it powered up and went through self check. I was really happy and I proceeded to remount it to my desk (I use bolts). By the time I was done a minute later, it was once again dead as a doornail and this time for good. I tried again today and I also tried to mount it on a laptop just to see if that made any difference. I amended my ticket to Thrustmaster and I took videos of the wheel and some of my attempts to troubleshoot it., Based on the research I have done so far, the culprit may be the circuit board and TM often send that along with instructions on how to replace it. I don;t have a problem with that. However, I am, posting here and if a couple of other places to make sure I a,m not forgetting anything. No fuses or key combo to press. Anything like that.(I already tried the only key combo used in this cases and I also tried to install the firmware again. It should be noted that I flashed the firmware when I first received the wheel and it has been working just great since. My mounting procedure is very low impact. I bolt the wheel on my desk with a electric drill (clutched) and I have the wires coming up through the desk as well. I also use a USB strip with a switch so that when I turn it on I don;t have to hold the plug with one hand and the wheel with the other. I have used the same system for my G25 for years. I am certainly very disappointed. Fortunately, the wheel is under warranty and ironically, right before discovering the power was broken, I had received the Proof of purchase from the guy I bought the wheel from. I have until April 20 to repair the wheel under warranty. If any of you guys have any ideas or went through the process of fixing a wheel with the same problem, I'd love to hear about your experience. Thank you.
