Hi @Shudley can you describe the specific issue with your Samsung TV. in general terms boards/screens are designed for specific models.
In any case cannot really go into any interchangeability in the public forum, discussion of D.I.Y. repairs is not permitted. https://eu.community.samsung.com/t5/tv/community-policy-on-dangerous-diy-unorthodox-repair-advice/td...
For safety reasons products should be inspected by a qualified engineer/technician if a repair is likely to be required. Samsung Supporty details are here https://www.samsung.com/uk/support/contact/
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
