We have a Panasonic Blu Ray player that for some reason won't play the blu ray discs only regular discs now???

If unit does this with all blue ray disks,old and new ones, then the unit is defective. Period

Router has nothing to do with the playback of a disk!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

i'm having the same problem with regular dvd's. it'll play blu-rays o problem

Need more info. Does the player accept the disc? If so, do you hear the disc spinning inside? If not, what does the player do? Does it kick the disc back out? Will this player accept and play other discs?

Every blu ray or dvd player sold in the world comes as standard unlocked to play any disc from any region. On the fifth play of a disc the DVD or Bluray will become locked to that region. So if you play 5 USA dvd's on the player after the fifth disc has been played only US dvd's will be recognised by the player, Same applies to BLUrays. So if i were you i would be careful about what discs you are putting in the player. Otherwise you will be left with a bluray player that cannot be used in Australia. After that happens the only way to play other region discs would be to get the player unlocked. Another point to add , a blueray player has two lasers one to play bluray and another to play DVD's. Lasers can fail so you could be able to play DVD's but not Bluray or vice versa depending on which laser has failed.

see the cause and remedies:
Does not play disc

1. No disc. - Load a disc into the tray.
2. Disc has been loaded upside down. Place the disc with the label side up.
3. Disc region code does not match region code of the player.
4. Disc type is not the correct type to play.
5. Disc is damaged or dirty. Clean the disc or try another.
6. Moisture may be condensed inside the unit. Remove the disc and the leave the power on for one or two hours.

Finally the OPU, optical pickup unit contain too the lasser beam, NOT are reading the TOC of disk,+Syscon can be defective. You must go to the repair shop TV for fix it. this a complex equipment.
see tje block diagram.
God bless you

You may have come close to what the issue is---Blu Ray for several design reasons is much more critical than DVD---seen a lot with this issue----either a dirty or a failing optical pickup in the unit---I know as when first started seeing it in our shop changed a few and since under warranty found the answer--optical unit was the problem---shortly after that they started just exchanging the cheaper units.

Due to the nature of players often if the optical Pickup unit inside is dirty or failing Blu-rays will not play but DVD's will.

Since you have done all the updates then Samsung should replace your model, there is nothing more that can be done until they come up with a solution.

There have been issues with firmware, if that is the case they should offer a method to reverse the process instead of telling you to press a few buttons which will do nothing. I would pursue Panasonic to get them to offer you a solution to remedy the matter.

There may be a issue with the assembly, blu-ray plays with more precision and speed, for some reason it is not slowing down to play the regular DVD's may be a padder motor problem.
