My panasonic sa-pt460 surround sound system won't play any new dvds, does not recognise them in the system and says no disc, is this something that can be fixed or just because of the age of the syste

Sounds like it may have a hardware problem, specially if sometimes it plays one disc, and others not (I mean the same disc).

But in any case, check to see if there are any firmware updates from Panasonic, that may fix the not recognising new discs issue.

Usually firmware updates are done by formatting a USB pen with a manufacturer's tool and then booting the unit from that USB.
In some others just leaving the firmware file in the USB, and the unit will pick it up an upgrade.

Unable to read disc;cleaned the lens but just says "loading. . ." on screen.

The problem is in the laser pickup assembly, overtime the laser becomes weaker until it can no longer read the disc. Unfortunately the only option is to replace the DVD player, because the cost to repair will greatly exceed the price of a new one.

Unit fell on the floor and now gets stuck while "Reading Disk .." after hitting play. Can hear the mechanism start and stop continually but never gets past the reading disk stage. Perhaps...

1. Open unit as if you were loading a disc.
2. Locate laser lens and sliding lens assy.
3. Take a non-conductive material (wood, plastic) and try moving the laser assy. along the track.
NOTE: you may have to be a bit heavy-handed to make the laser assy. move.
4. Move it in one direction but only far enough to free the jammed laser mechanism
5. Reinstall a DVD and press "play"

My panasonic sa-mt1 says that there is no dvd in the tray, it says no dvd?.

There a few common reasons why dvd players will not recognize the disk.

1. If the disc to really dirty or scratched the optical reader will not be able to read it.

2. The optical lens could be dirty and will need to be cleaned. If the laser can not see (so to speak) the disc and read the tracks it will not recognize the disc.


3. If the spindle motor does not spin the disc, the optical lens will not read the disc and not recognize it.


4. If there is a malfunction with the optical reader assembly (the laser malfunctions) it will not read the discs. The whole optical assembly is the entire optical lens and circuit board seen in the above picture along with a few other components not seen.

5. The disc tray could be out of alignment. This usually does not happen unless the device has been treated roughly or dropped.


In most cases, a simple cleaning of the discs and the optical lens will solve the problem. If the disc is not spinning, the spindle motor has malfunctioned and it will need to be replace which with parts and labor will cost you roughly between $70-90 dollars (most is labor) depending on the prices in your area that service technicians charge. The most expensive part to replace is the whole optical assembly, which depending on how much you paid for the device, it might be cheaper to buy a new player (average estimated cost of replacement between $ 200-280 most of which is the part unless you can find a great deal some where).

Check to see if your discs are scratched or dirty by holding them up to the light and tilting them back and forth. Try new disc in your machine to see if the problem still persists, if it does then try cleaning the optical lens. You can purchase cleaning discs to do this for you or you can do it manually. You can also purchase things that will help clean your discs as well. For a more detailed description of cleaning procedures, please review my profile where you will find my tips. Check to make sure the discs are spinning. You can remove the cover if you like or you can listen really close to hear if the discs are spinning up. If the discs start and stop the entire process without spinning up after you have cleaned the discs and lens, the problem could be that the spindle motor is about to go out. If the discs are not seated in the tray properly or the tray itself if out of alignment then it could cause the machine to not read the disc properly.

I hope this helps you solve or determine what the device malfunction is. Please let me know if you need further assistance.

If you would not mind, please rate my help. I would greatly appreciate it. Thank you.

I have panasonic DVD player SA-MT1. It doesn't play dvds anymore. Showing "no disc" messege. But it still playing burned dvds.

so you are telling me it will play DVD+Rs but not pressed DVD movies? hmmm....try cleaning the laser lens real good. If still you have problems, it is time to junk it. These things are more expensive to repair than to purchase a new or better one.

I have the panasonic DVR-255. after about 20 months of recording on DVD-R discs it reads some un-finalized discs as unreadable, won't finalized some discs that have just been recorded (displays...

With use, the laser tends to weaken. It is possible that it has reached the end of its lifespan. It is also possible that with use, the tracking alignment has drifted off specs.

You can call Panasonic to find out where their service rep is located for you to have a quotation for repair. If it is only tracking alignment that needs to be re-set up, the repair cost would be an hour or two for the work done. If the laser is defective, then the repair will be fairly expensive.

Unlock code for Panasonic SA-MT1

Unfortunately I have discovered there is no easy way to unlock this player for free. It seems that Panasonic is starting to become very tough when it comes to unlocking their DVD players. Maybe it is because of pressure from the Movie industry? The only way I could find how to unlock the DVD player is by using a "Unlock DVD". I tried to find this DVD file on the internet for free but I could not and so Ive given up. I did find a website that sells its but I have no guarantee that it will work.

Sorry I could not find the answer.

Thanks for reading!
