Solved! Motherboard replacement

[David alin]

Can a 50inch motherboard and Tcon board work on a 55inch screen if they are all from the same brand TCL

The backlight and panel will need more power and eventually some features and ports can´t be used.
You will have to try yourself, but I wouldn´t recommend it.

If the original boards have the exact same part numbers as the replacements then they should work.
