Open the case. Disconnect the ribbons from the main control PCB. Remove the screws holding down the PCB and the rear connectors. Take the board out. Find a chip with the number MR27T1602L or similar - it is called a P2ROM. Run a screwdriver slowly all around this chip to possibly drain erroneous (yea right) data. There is a small chip diagonal to the P2ROM right next to it. I could not read what it was but i suspect it is for temporary data storage - possibly a serial ROM of some sorts. Run the *SMALL* screwdriver around the 8 legs on that chip slowly ensuring that it connects each 2 legs to each other along the way. Now this will either 1) Do Nothing 2) Mess up the chips or 3) Clear out any bad (read factory installed failure timers) data from the chips. Doing this task over a period of about 3 hours seemed to have solved the problem. Now it could have been as simple as disconnecting the ribbons to the board and leaving it sit for a few hours to drain (memory caps to lose charge). I don't know. But I know after doing this my player started working again. Good Luck to all who try.

Why is it a sony BDP-S1200 not play DVD discs but can play blue ray discs?


Check that you are playing the correct region coded discs for your player. Blu-Ray discs tend to be universal but not DVDs. If you are playing Region2 disc when the player is set for region 1 (American) then they won't play and again Vice Versa.

Check the mode of operation. There can be a setting where it just plays one disc. Random or mixed will give you more songs to get to other discs.

Have you tried inserting other game discs? like 3 types of disc. If your Wii console plays those discs and don't play with the game disc that you wanted to play, then the format of that disc is not recognized by console. Some disc formats are sometimes incompatible with the player console.

My sony DBP 300 is not playng the Disc . It plays the beginng of the disc but seems to freeze and we are unable to play the blu ray disc movie


Try selecting another disc to play, if the next disc plays, it may be the first disc that will not play, also make sure that it is not a 'burnt' copy, if it is....the copyrights may have prevented it from the format being proper. if second movie does not play, it may be the reader inside is dusty/damaged. Also look at dvd disc to make sure it is not smudged/scratched or dirty. take appropriate cleaning measure if it is smudged or dirty,

How to play region A blu ray discs on region c Blu ray player. i have bought this player in India but would like to play BD discs got for USA, and the player does not plays such disc.


The Player will not play the Blu-ray discs other than Region C.
This is because all the Blu-ray/DVD Players are designed such way that it will play only the discs that are manufactured and sold in the same country where the Player is manufactured.

You can play the discs that are "Region ALL".

However, you may try copying the content of the Region A/B Blu-ray discs to a Computer then create a video Blu-ray disc to check whether you can play them in the BDPS370.

Plays some won't play others firmware is up to


Please check in the manual provided which regions disc your Blue ray disc player can play. Check the same region code at the back cover of the Blue Disc you want to play. If it is same there is no problem in playing but if it is other than the one your player can play, it won't read or play. Try to get Discs which have all regions marked on them

Disc spins, then " Type of disc can not be played" message


it means the format of the type of cd u put in cannot be played by the system.

try playing the disc it on another player, if it does the same, it means the disc cannot be played. some players dont play mp3 format, blu ray, and some others, so you can check the kind of disc you want to play on it.

goodluck

I have a Sony Psyc CD Walkman D-Ej010 and I will have a cd in there at it will play for a few minutes and then stop and say no-disc. What could be the problem?


There may be a couple of reasons why a NO DISC , DISC ERROR or INSERT DISC error may appear in the display of your CD player. Try doing the following steps to troubleshoot why the error is displayed:
  • For disc players with a HOLD switch, make sure to move the switch to the OFF position.
  • Verify that the disc being used is supported by the CD player. NOTE: CD players do not support VCD or DVD discs. In addition, some CD players do not support CD-R or CD-RW discs that are created by a CD burner. For information regarding disc compatibility with your player, refer to the operating instructions supplied with the product
  • Ensure a disc has been inserted into the player. Make sure that the disc is inserted correctly, with the playback side of the disc facing down on the disc tray.
  • If the disc still does not play, attempt to play a different, commercially-produced disc.
  • NOTE: If more than one of the commercially-produced discs do not play, verify whether the discs are extended-length discs. Some players are not able to play discs where the recording exceeds the standard 74 minutes. If the recording of the disc is longer than 74 minutes, it is possible that some of the specifications of that disc were compromised and therefore, the CD player will not recognize that disc.
  • If the disc is dirty with fingerprints or smudges, or if the disc is scratched or broken, the CD player may not recognize the disc.Clean the disc using a soft, dry cloth.
  • Properly reinsert the disc into the player.
  • Attempt to play the disc again.
  • Only press the PLAY button once. If the PLAY button is pressed more than once, the disc may stop playing.
  • If the disc is still not recognized, remove the disc and leave the CD player powered on for approximately one hour to resolve the possibility of moisture condensation inside the player.
  • Please use a Lens Cleaning disc and check if that helps.

If the issue persists, please click hear to locate the repair facility near your area.

Thanks for understanding. Please let me know if you require any clarifications.
