I am finding that with my Sony BDP-S470 Blu-Ray player, some discs are very noisy to the point of being unwatchable.

At first I concluded only some Blu-Ray discs were a problem (as opposed to DVDs), but today I've noticed there can be problems with DVDs too.

This youtube clip demonstrates:

The Homeland series, for example, is very confusing. Of the 4 discs that make up the series, the first 3 weren't too bad, but the 4th is unbearably noisy (and I've used it in my video).

Thinking the disc was faulty, I asked a relative to try it in his player, and he says it's fine. Every time I play it in my BDP-S470, it's noisy.

The Aliens disc in the video is brand new, so unlikely to be scratched/warped, I'd hope.

The player is over 3 years old. Any ideas?

If you feel confident about taking the beast apart, take the lid off and very gently clean the laser with a barely damp cotton bud. Either use clean tap water or Isopropyl alcohol but be very sparing, don't have the bud dripping wet.

If that does not appeal try a lens cleaning disk (any type, CD, DVD or Blu-Ray).

It may be the laser lens is slightly dirty so the player is having a minor struggle to read the disk properly. I've known similar problems reading disks occur with CD players mainly and a quick wash and brush up often sorts them.

And lets face it a cotton bud or even a cleaning disk is a hell of a lot cheaper than a new player! Especially if it works
