Please assist with black screen with audio. - Sony Bravia KDL-37M4000 37 in. LCD HDTV

Chances are its the Inverter. However since the audio doesnt work either its also possible that the main board could be the cause. As in most cases audio will still work when an inverter fails. so its about a 50% for each board when the audio doesnt work either. You can get some free assistance yo help troubleshoot which board is at fault from www.tvcircuitboards.com they should also have replacement boards for your model.

if you need further assistance please let me know. If this helped solve your problem then please feel free to rate it accordingly. Thanks, Midwest-tek

make sure the video cable is plugged into the correct input and that there is no cuts or crimps in the video cable. Also try a different video input. As sometimes a tv will have s-video input and a rca input and if you dont have it in the selected video input it might not display.
but because you have audio i am confident that your problem lies in the video input not being properly plugged in/selected or the cable is bad.
So try a input that you know works and turn off the wii then unplug the video/audio cable from the wii and plug it back in.
If you need further assistance please feel free to follow up with a comment and i will be here to assist you. If this assisted you please feel free to rate the solution. thanks and have a great day.
