You would have to obtain the datasheets for both the TV panels that you wished to swap, the old and the new to verify that the new panel is compatible with the boards that will have to connect to it . Also the new panel, panel mounts may be located in different spots so again it may not be compatible with the frame that it has to go into
The only things to try are to find the panel make and model number, usually found on the back of the panel itself and try and locate a replacement using that information or to source an exact same model faulty TV where the panel appears to be OK and hopefully it may be a board problem that nobody can be bothered fixing.
The best option is to advertise the TV as faulty screen - good for parts to try and recoup some of the cost towards a new TV. Working boards are always in demand.
