I have a Samsung ht-bd7200 blu ray come cinema system 12 months old, Doesn't get used a great deal so certainly isn't worn out. The problem is that it has stopped playing the main audio track, the background sound is fine & all seems ok until a main character speaks then the sound is very muffled....I've updated the firmware to the latest version & even re-set the unit to the factory setting...any ideas anyone?

SOURCE: firmware update

Here's the link to the newest firmware.

SOURCE: Unit plays DVD but no longer Blu Rays

That is because of a dirty or defective lens. When lens is dirty, the unit may still operate on regular CDs and DVDs and not be reading BD.

Try first using a lens cleaner for Blue Ray: Maxell 190054 Blu-Ray Lens Cleaner

If that does not work, the unit may be disassembled, and lense cleaned with q tips and isopropyl alcohol or cleaning solution. See below:

Being this a blue ray unit , I would suggest calling support instead of disassembling the unit by yourself.

SOURCE: Samsung BD-C5500C with latest firmware will not

Hello,

I don't think this is a software update issue. Just as you said that the player has the latest firmware installed on it. Software update and latest firmware are the same thing.

I think this is a incompatibility issue. The disc is not 100% compatible with the player and that is why there is no audio via sound.

But one more thing you can try is to enter the player's menu, under settings, check audio settings. You can change the sound settings to mono, save settings and try again.

Good luck.
