Hello,
looks like something similar happened to me today. My Warthog stick has just died. Since I´m out of warranty I´ve opened it up to have a look if there´s something fried inside and indeed it was. I´ve attached a picture of the fried board. Is it the ssame part you had to replace on the dead stick? If so, what part exactly do I need to replace it? I have to admit that I have very very limited knowledge of electronics, but I´m not afraid of soldering to bring my warthog back to life. I´ve also contacted Thrustmaster support for a replacement board, but after reading about the experiences many users had with TM support I don´t expect much of them. So I´m just checking my options what I can do to repair it. Any help is appreciated.
