Wont play blu ray movies or reg movies says no disc

If it plays other Blue Ray discs OK then either the disc is faulty or it is the wrong region. If it previously played, then my bet is that the disc has a scratch or dirt on it. If you have another blue-ray player or you have a friend with one try it on that or theirs.

MP4 or AVI files will definitely work but make sure your USB memory is formatted in FAT32.

You need a blu ray player to play blu ray discs

Besides the Blu-ray drive, you also need a Blu-ray player software to play the Blu-ray disc. You can try Leawo Blu-ray Player which is a free program and a 4K player.

With people downloading movies illegally, companies have put blocks on DVD's, unfortunately making the DVD unplayable for some blue-ray players

are you using a software that plays blu rays?

Please check the region code on the BD or DVD. It should match the region code set in the system. Otherwise the disc will not play

try setting the console back to factory settings, i had the oposite problem, would play games but not movies. will it play blu-ray movies or regular? if it doesnt play blu-rays, your disc reader may have gone bad.

Occasionally the software on most blu-ray players needs to be updated to the newest technology. The reason some discs play and some don't is because the discs that play are most-likely older movies or from a company that still used the "outdated" software. So the discs that don't play (most likely discs made with the updated software) won't play on your player until you've update the player's software. To do this visit, in your case, Sony's website for update info. There are a few ways you can get the info. You can download it directly to your player (if it has online accessibility) or you can request that they send you an update disc. Either way, most companies provide the update for free. Hope this helps, good luck!
