Can I change internal components with another size samsung tv?

Hi,

I have a samsung tv ( UE50J5500AK) the tv made a pop one day and hasnt been getting power or turning on since. Im certain its the power unit in the back. I have recently been trying to find another faulty screened tv but working . The same model number and size to move and replace all the internal circuit boards into the tv i already have. I came across a Samsung tv exactly like mine but a 48” version. Model number ( UE48J5500AK). So this tv is essentially the same country. The same year. The same model number but 2” different size screen. Isit possible to use these parts to replace with the ones in the tv i have? I read a forum of someone doing it with different size screens in older tvs which worked. If not, what about using a tv with the same screen size but slight different model specifications like UE50J6000AK.

Any help appreciated, thanks.
