Ps3 makes loud humming sound while playing blu-ray movies

Make sure that your firmware is updated correctly. Also make sure the games are the correct region for the unit you're playing on. You may have an incorrect region setup on the PS3. PS3 games are region locked, either being PAL or NTSC. If the PS3 is set to read PAL (by being set to a region that is PAL, like the UK, Europe, and Japan) it will not read or play an NTSC disc.

Misconfigured or corrupted firmware installations can also cause this problem. Furthermore, pirated games will not play, because they do not have the appropriate security key on the disc.

You can try testing this by creating a new profile on the PS3 and trying to play the games. If you can play them with the new profile, then there is a corruption with the old profile. If you can't play them in the new profile, then it could be the firmware.

Lastly you may have a blown drive. Most PS3 games are dual layer blu ray discs capable of storing large amounts of data. The blu ray drive in the PS3 uses a sequenced dual laser to read the game. If one of the laser emitters has blown, it won't read the game correctly. However, since it doesn't use both emitters to read blu ray movie disks or dvds they'll still play correctly.

Will it play anything? The laser eye may need to be cleaned. Sometimes the drive will play DVDs but not games, or games and bluray movies, but not DVDs .... in that situation, the bluray laser may need to be replaced

A bad laser could affect the sound cause it can't read all the information from the disc. Try games as well and see if it does the same thing, sounds like a new drive is in order. There is one laser in those drives and require different strengths to read different discs. Also try a music disc that you know is good. If your still getting the same issue then get the drive replaced or just replace the laser if you have some technical knowledge.

Well if the regular dvd's dont work.. I would recommend you to buy Blu-Ray movies instead.. PS3 is the best known blu-ray player. buy at least one blu-ray movie and try that.

thats becouse it a BLU-RAY it is diffrent i figured out the hrd way 2 :P

As long as the movies and games are the actual things and not some burnt rip-off discs you'll be fine. The movie companies do this so their stuff isn't copied illegally.

Merry Christmas!

If this has helped you, please give me a good rating!

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.

I would start with a firmware update (2.60) and also a full system restore. That should fix the problem. Let me know. I'm a PS3 expert!
