will a av board out of a 42 inch panasonic tv work in a 50 inch panasonic tv ?

steve.d.wright maybe ;-> Depends on the model and depends on the board. You would need to look at the board numbers and see if they are at least somewhat compatible. Next would be making sure that the connectors are all the same. So, without actually seeing it and comparing the boards it will be difficult to answer. Also even if they look the same, doesn’t mean the firmware etc. will be the same. Just like anything else in life, “Nothing ventured, nothing gained” so if the connectors are the same I would at least try it out. If you have the boards you can post some pictures of those with your Question so that we can see what you see. Adding images to an existing question
