I have been using this device without real problems for several years. I just checked for a firmware upgrade and found one. After installation, the screen went black and I received a "No signal" message. The unit turns off and on; it recognizes and plays DVDs, but there is no signal being sent to the TV anymore. The cables have been in place for a long time and were not touched; there is no simple connection issue. This occurred immediately after a firmware upgrade. Does anyone have any thoughts? I am not thrilled with the prospect of having to buy a new media server.
