Good evening, all. Had a Wii brought to me to work on -- which turned out to have no video. The Wii turns on, it would appear, and the TV flickers in response as it normally would just before it should bring up the health and safety screen. After looking up the problem, and seeing that most responses dealt with bricks, I decided to try the savemiifrii method, which successfully reported that the system was on 3.1U. I find it a little hard to believe that the owner hasn't been online or at least hasn't played any games newer than 3.1 firmware, so I strongly suspect that this is the result of a failed mod. (On the other hand, if the laser failed or they were using a badly scratched disc during a system update, I suppose the same thing could have happened.) My question, though, is: If this system has been improperly modded and/or downgraded, am I risking further damage -- and unrecoverable brick -- by simply dropping a retail disc with newer firmware? If so, what additional steps/precautions do I need to take here, in order to attempt to restore this thing to a functional state?
