So I have a Vizio M3d550kde around 2011 per date on a sub board. The tv works well except that the input on HDMI inputs 1-4 are all displayed in black and white - (other inputs not tested and unknown if they are good or not.) -where the menu selection and initiation screen show full fine color. I was thinking ok fine Main board replacement, but then I thought wait a minute, the menu display comes from the Main board. Any thoughts or suggestion for repair?
I did a factory reset just to make sure someone didn't change a setting that would allow this weird behavior from the tv.
The tv is a salvage to be given away, but more importantly it saves it from the land fill. The TV has never been opened until now. Looks great inside..
