SOURCE: Display says "LOCKED", won't eject disk, all other functions work. Need unlock procedure.

How I got my DVD from ”lock” condition

My DVD (Panasonic m: DMR-ES10) had gone to ”locked” condition without any warning.

Perhaps the reason was that I transfered the machine when it was on and recording was going…

Guidebook didn´t help to resolve the problem, neither Internet. Finally I managed to solve the promlem . This is how i did step by step:

1) Power on
2) Hello
3) read
4) no disc
5) functions
6) to others
7) setup
8) select down arrow
9) disc
10) select right arrow
11) setings for playback
12) enter
13) ratings (level8)
14) enter
15) No limit
16) enter
17) ”The Recorder is now unlocked” (picture of open lock)
18) enter
19) return
20) return

After this DVD works normally.

SOURCE: Sony RM-ASP001 for 400 disk changer stopped working

Try the command code switch. I recently had a similar problem when my remote suddenly stopped working. It worked fine one time but nothing the next time I tried it.

I checked the emitter with a digital camera and found it was not working. I did the remote reset (remove batteries and push all the buttons twice, reinsert batteries) and the emitter was now working. However, the remote would still not control the base unit. I did the remote base code reset (push power, volume and TV/DVD buttons together) but this did not help. I then checked the command code switch. This is a small three position slide switch located in the battery compartment on the remote. I slid the switch back and forth several times returning to the default number one setting where it was before. I did not change anything on the base unit but the remote now worked.

Hope this helps.

SOURCE: My Sony Bravia remote control is slowly loosing it's functions.

You can repair some of these remotes. Usually the hard part is getting the cover off. they are not really made to be serviced. The problem with most all remotes that start doing what you describe is either wear or something spilled on it. You can fix it. Sony remotes may have 1 screw in the battery compartment. remove it and try sliding the front and back. If that dosen't work try prying from one side with a sharp edege. If you do manage to get it open take the PC board out. You will see a rubber like membrane that lays against the board. Try cleaning that with a qtip and rubbing alcahol. Then clean the PC board the same way especially where the pads of rubber contact the board. Make sure it's completely dry and snap it back together. If it works better good, if not the pads are to worn and you just have to replace. Good Luck.

SOURCE: batteries leaked, cleaned as best I could, but

If you have had a battery leak then this is a very bad thing. It's possible that the battery acid could have corrupted the system board in the remote. I would call Sony to see if they have any suggestions for you, however I think you may end up needing to replace the remote.

SOURCE: CD player says "no disk" when there is disk in player.

My CFD-f10 showed "no disk" after not being used for a few months. Before that it began to stick or skip toward the end of the disk. The trouble was the drive mechanism was failing to move easily due to poor lubrication of the CD drive mechanism. It can be lubricated, but the job is difficult. The top must be opened. First unplug from 120 V and also remove all 6 D batteries, then take 7 screws out from the top. One is under the Tape lid. Two are under the CD lid. Four are along the back. Also take out the screw from the bottom that holds the antenna. There are little arrows next to those screws. Do not take out any more screws than those. Gently lift the top, which includes the CD and tape lids, from the rear while moving the top a little toward the rear. It will seem very tight at first. Do not force it, but keep gently prying. There are circuit boards close to the seam, so do not pry open with long tools. The rear will lift up about 1.5". The handle stays attached to the bottom. Then the flat ribbon cable must be pulled from the ivory socket. The ends of the cable stick into the socket. The socket remains on the circuit board. As the top is raised further, unplug the cables preventing movement, Carefully note where they are plugged in. After the top is opened about 90 degrees, leaving the tape drive still close to the bottom cabinet, remove the 4 CD drive attachment screws with metal washers at the colored rubber washers and also the cable. Now the CD drive can be removed. With very fine synthetic clock oil, I lubricated the end of the motor shaft, (lift the plastic cover a little by unclipping the little snaps.) Very gently operate the mechanism by pushing on the larger gears. Sony had lubricated most, but the lub must have gotten thick with age. Put a little synthetic oil wherever there are moving parts. By turning the gears by hand, you will tell if all is working freely. Then carefully put all back together. Yes the CFD-f10 now does play CDs again!!! I do not know for how long. (Sony style outlet online is selling the newer refurbished CFD-S350 silver boom boxes for about $37.00, which also uses the more desirable 6 "D" batteries, and comes with remote. I have one on order.) The synthetic clock oil can be obtained from any company selling jewery or clock parts, but it is quite expensive, easily half what the refurbished CFD-S350 costs.

I currently own a Sony-400 CDP CX400, i was wondering if the remote control for my CX400 is compatible with the cx455, I also wanted to know what is the major differences in these two products?


just use the remote and if it works then it is compatible
many companies use the same remote frequencies between models as it saves on expense of producing new units
there may be a problem if the newer unit has extra items to remote control

What is the unlock code


If you just need the unlock code see below

You will need to use a "universal" remote control like the One4All 'Kameleon'.

Firstly configure the remote for your sony DVD player:

1. select dvd device on remote
2. hold magic button until rabbit comes out
3. enter device code 0533

Now we need to program buttons 1..5 (you may want to use the buttons with roman numbers at the bottom of the remote, and use another button for V, which doesn't exist) with the following codes, read below for instructions:
1 - 189
2 - 255
3 - 095
4 - 221
5 - 079

For some "universal" remotes, all of the buttons you need to reprogram need to be prefixed by 00. So 1 would be '00189'

This is how you program those numbers:
1. Hold magic button until rabbit comes out.
2. Press 994.
3. Press magic (don't hold).
4. Enter 3 digit code from above.
5. Press button (1..5) where to program it.
6. Repeat steps 1 to 5 for all keys.

That works, but more information on macros is included in the one4all manual for you particular model.

Having set up the remote with the codes unlock the player as follows:

1. Remove disk, put player on standby.
2. Press 1,2,3,4,5 - SUCCESS is displayed and player starts up.
3. Press 1,2,3,4,5 - player shuts down and the unit is region free.

Note that you try this at your own risk as Sony do not support this "feature".

Sony remote RM-DX500 not working with Disc Explorer 400 DVP-CX985V, but does work with tv. How can I program it to work the dvd player?


There are 2 set's of command switch's for the dvd player, a 3 position command switch on the back side of the dvd player and another 3 position command switch on the inside of the remote right next to the batteries, easiest option is to remove batteries from remote and test each one of the 3 position switch's labeled 1,2 & 3 and test remote control.
