Can I replace a TV main board with one from a smaller screen size

[Kairi]

Hello,

I have in my possession a Samsung LE47C750R2K with a faulty main board which has a part number of BN41-01423B BN94-03388E.

It seems like this board is used in both 40 inch and 47 inch screen TVs (LE40C750R2K and LE47C750R2K). The boards are physically identical with the same part number but there's a bar code sticker on it with the TV model written on it.

I would like to know whether it's possible to fit a main board intended for the LE40C750R2K in a LE47C750R2K. Or are there some sort of programming to make it work for a particular screen size only rendering it non-interchangeable between the different screen sizes?

It will likely work, give it a try. If the picture is not right go into the service menu and change the model or panel number

first go to Samsung website for firmware.. if you find the firmware all same size as you mentioned your type LE47C750R2K and other size then go head and need to do at SM as R_J suggest . . if there firmware as update each panel size individual then will be hard to do

I went to the Samsung website but there doesn't appear to be firmware available apart from 2 upgrade files which appears to be the same

I wan to be sure that the board intended for the 40 inch will work in the 46 inch before I commit to buy the replacement board.

I have put a Samsung UN40D main board in UN46D (BN97 part number matched and shopjimmy said they were compatible) and an LG 47LN main (had lying around and purchased another time because it was cheaper) in a 42LN. TVs worked without having to make changes in the service menu.
