Hi all, i think I've managed to fry one of my usrp board. I have two rev 4.1 usrp boards and have been working with them for a couple of months. i had attached the tvrx daughter board and a wire connected to it as an antenna. i was moving the wire around to get a better reception from the usrp_wfm_rcv.py file when i let go of the wire and it fell in to the surge protector. it stopped working so i unpluged the usrp board and pluged it back in and tried running the program and got the following error: Traceback (most recent call last): File "./usrp_wfm_rcv.py", line 266, in ? app = stdgui.stdapp (wfm_rx_graph, "USRP WFM RX") File "/usr/local/lib/python2.4/site-packages/gnuradio/wxgui/stdgui.py", line 36, in __init__ wx.App.__init__ (self, redirect=False) File "/usr/lib/python2.4/site-packages/wx-2.6-gtk2-unicode/wx/_core.py", line 7473, in __init__

i tried it with the other usrp board and every thing works fine so i know the daughter board is working fine.. when i open a second terminal and use the command $ tail -f /var/log/messages when i plug in the usb it has no effect when the fried usrp board is on the other end..
the green led does blink (fast) when the usrp board is powered up but seems like i cant get any connection between the usrp and my pc..
any suggestions will be greatly appreciated
thank you
