Only the back ground sound is heard, can't here what the main actors are saying, Samsung BD-P1500, HT-AS720S, and Series 7 750 TV, trying to play a DVD, Dolby Surround 5.1

when you say it'll play the sound, do you mean sound from the videos or sound as in it'll play music cds etc.
?

All the disks?
You may have firmware problem, this is one of the reson I do not own BRAY since you have to keep updating the firmware so you can play some of the new released BRAY disk.

I had to update my firmware on my Samsung BD-P1500. Followed the instructions on the Samsung Website. Make sure you use ISO Burning SW. I wasted 3 CD-R trying to burn the disk correctly.

Hey AJ,

Follow this link: http://www.samsung.com/us/support/detail/supportPrdDetail.do?menu=SP01&prd_ia_cd=&prd_mdl_cd=&prd_mdl_name=BD-P1500 Click on firmware under the downloads tab. Download the upgrade guide and it will instruct you on how to burn off a copy of the updated firmware for this model and load it into your player. It should take care of your issue.

Is it new? Then send it for warranty claim. Is it old? Warranty expired? Then send it for repair. U have an internal problem. Either with circuitry or with the pick up lens. Most cases if the power is there, then the issue is with the lens. In optical disc drives, lens is the main culprit which fails most of the time. Just in case if u don't know, pick up lens is what reads the cd/dvd/bluray through a laser.

I believe on startup, you need to hold the fast-forward button on the unit, until you see something about reset in progress...

If you are trying to use the remote that came with the dvd player you most likely can't get it to work with the TV. If it IS in fact a universal remote, then you need to check the codes that come both with the tv and with the remote. Post back with any more questions or info for further help. Thanks for choosing Fixya!

644 works with the Samsung BD-P1590/BD-P1590C/BD-P1600 om my Blue Button Dish Remote for the 722k.

If your system has hdmi in puts put the blu ray player into it then from hdmi out on system to hdmi in on your tv.Now take a phono lead from tv out put to a input on your system,could be marked "aux,tv,sat".For tv sound set the system to prologic2,blu rays should decode themselves,if not check settings for audio out on player.
hope this helps.
