    Vizio M55-F0 Cannot be turned on

    I found this tv's situation is very complicated. It will take a long time for me to tell what I found. Therefore, if you don't mind, before I tell the complete story of what I found, I would like to ask some questions. Of course, if the complete story is needed, I will do so.

    The tv cannot be turned on. I found that the heat sink on the mainboard is so hot to touch even if it is just plugged into the wall outlet but without turning on the tv. Does this indicate that something wrong that needs to replace the mainboard or the other boards?

    Sounds like the main board is screwed to me. It should not get hot like that in stby.
