My bluray SAMSUNG HT C5200 don t play the bluray discs , i cleaned up the lenses but still don t work.what should i do to fix that issue

Most bluray players have 2 eyes....one for dvds and cds and one for blurays. If cleaning by hand dont work reader could have gone bad.

What type of blu-ray disks? Store bought or homemade or ALL blu-ray disks? Have you tried cleaning the lenses?

1) Switch Player off then On (this is to clean-boot firmware).
2) Wait until main menu appears
3) Open Disc Tray and Close Disc Tray (May not be necessary)
4) As soon as "No Disc" is displayed quickly press REPEAT on
remote quickly use the following code for your current
region:
Region 1: Press - 2,9,3,3,4
Region 2: Press - 5,7,5,3,8
Region 3: Press - 5,6,7,3,2
Region 4: Press - 7,6,8,8,4
Region 5: Press - 5,3,8,1,4
Region 6: Press - 2,4,4,6,2
5) Your current Region will appear in the top-right corner
6) Quickly Press "9" before it disappears (It should replace
the code with a "9" in the corner)
7) Switch Player Off and then On again.

Note that REPEAT is part of the code so one smooth press of
6 keys is required.

There isn`t currently a region hack for Blue-Ray Disks

..I would assume that you have carefully cleaned the lense and inspected the flexible ribbon cable..try replacing the spindle motor..in our case they are not expensive..good luck Elben

there are two lasers inside a blueray one for normal dvds and cd's and the other for blue ray films, either the laser lense is dirty or it has burnt itself out and will need replacing , if a clean doesnt get it working

Try resetting the system turn power off then press and hold stop button on Main unit for at least 5 seconds this is main system reset it may well do the trick for you

i m dvd home cinema sound system ht q20 every thing is ok but soung is not good plz hlep me

This issue is with the disc not your system.. it happens glad you got it fixed!!

No it does not. It will upscale regular DVD's to HD resolution, but that's an electronic trick. You'll need to buy a BluRay player to watch high definition discs.

The HD-DVD standard has been abandoned by Toshiba, so the Sony players are the one's to look for.

Yes. The laser lens in your player is dirty or failing. To fix your problem, try the following solutions: Clean the laser lens with a DVD player lense cleaning disc. Lense cleaning discs are available at many electronics retail stores.
