looking for a screen replacement
Where can i get a replacement screen for a Vizio d50u-d1 4K ultra ?
Unlike phones, 3rd party replacements are not made for Vizio TVs.
Also the model you listed is on Ebay for about $375 USD brand new for the whole TV, which likely is cheaper than finding a replacement screen.
You're best bet is to scavenge Ebay for a 'broken TV for Parts/Repair' or if you are luck a standalone screen.
