Playstation 4 will only play DVDs

[Lanereed01]

Hi, my friends old ps4 optical drive stopped working, he got a replacement drive, and now it only can play DVDs. He bought a new ps4 and gave me the old one. Can anyone help fix this?

You'll need to examine the drive, identify the make and model, and then check the manufacturer's specs to see if its bluray compatible.

I want it to be able tp play the game discs again.

In general console drives are locked to the hardware to prevent piracy, it doesn't play games because it sees that somebody messed with the drive.
Look up some guides on google, it's pretty complicated to make it work again since you have to replace a chip on the drive with the original one, the one that works with your console.
