I got a Wii from a yard sale. It is in pretty poor shape cosmetically, but when I plug it in and turn it on I get a black screen. I hit the power button and I see a flash of a green and red line across the screen anem d then it just goes black. I knownothing about the system as far as if any mods or anything has been done to it. I know it has been opened, because most of the screwsare missing, all of the little white covers are missing and 1 of the WiFi cables had been broken. I'm not sure if it has been hardware modded, I don't have any familarity with that, I've only done soft modding so I'm nit sure what to look for to see if it has been hardware modded. I pretty sure there is no Pre-loader becasue when I hold the reset button nothing comes up. I've read that most of the times ablackscreenor no video is because the Blutooth module went bad or got fried. I bought a new one and replaced it and still the same results. Any suugestions on what to try next?
