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.

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 am trying to unlock the region code for Sony BDP-S5100 with the URC7740. The hack program refers to "press and hold the &#147 key. Where or what is "&#"?


I would have to guess, that is probably not the correct remote. I feel I must inform you, trying to upgrade your firmware, from an unsavory hacker, can turn your unit into a brick(doorstop). IMO, proceed with caution.

I need to use a RCA remote to program a DVD and with out the codes and program a tv


Try writing to RCA Customer Service to see if it is a: feasible, and b: doable if they send you the right codes. If they elect to play ball, and they might if you offer to buy a new one as well, you will get a sheet of microscopic print that lists several paragraphs of models which will accept a particular set of codes you program into the remote, and then try that combination on all of your equipment, then try to next code on the list, ad nauseum, until you accidently find a combination that works. I have (eventually even gotten old, old equipment working in that way, including an off-off-off brand tv with all of the buttons on the front removed (toddler time) including the power button. Using some obscure setting for a generic remote that cost all of five or eight dollars gave me power on/off, volume, channel up-and-down, direct channel entry, input selection, and even a feature I did not know the tv had, a timer to have it shut itself off after a programmable number of minutes. If you have no such luck getting such a sheet of codes from the maker of the remote you want to add new functionality to (presumably, your existing remote does things that a "generic" remote may not, like setting gamma levels, color temperature, and muffler belt tension) which is the only good reason to hold onto it RATHER THAN FORK OVER FIVE OR TEN DOLLARS TO BUY A GENERIC REMOTE THAT WILL DUPLICATE THE CONTROLS YOU HAVE AND LET YOU CONTROL OTHER DEVICES AS WELL. I even have an extra one I could sell you, except it would cost more in postage than it would take to go to Walgreen's or KMart and buy a generic remote (with the pages of microscopic type listing suggestions of from one to several dozen possibilities for a CD player, a cassette tape recorder/player, a vcr, a tv set, etc. and you just put aside an afternoon to try entering different numbers for that remote with a given component, then trying the next number, and so on. Eventually you should hit something that works; write that "combination code" down, and move on don the line, determining what make of VCR you have, looking at that paragraph of codes, sighing deeply, and beginning to, again, trying code after code, attempting to "do something" with the remote after punching in a particular code, and then starting over with the next number. For $150-$400 yon by remote which not only let you manually program setting in this way, but also will try a series of attempts automatically until it finds a set of commands that "work". Best of all, if you have the original remote(s), for under $500 you can buy univeral "learning" remotes, that will take ALL your remotes, like the one you are holding, tell the Universal Remote what your programming, i.e. a VCR, and place the two remotes head-to-hear and press and hold down the fast-forward button on the "old" vcr remote, while simultaneously storing the correct "codes" into the "new" remote, then hitting save, and from that point on, your tablet or monster remote will control you VCR; then you perform the same steps with your stereo amplifier(s), receivers, phonographs, etc. The you can take all the batteries out of the remotes that came with each unit, and tape them securely to the face or back of the remote (so that you can use the remote to re-program the big remote again) and in that way you keep the battery from corroding in place due to inactivity and the eventual breakdown of almost any battery if given too much time: the same chemical reaction that makes the battery useful later, after not being able to power a device properly, goes "dead' and then, gasp, starts corroding away the metal springs and tabs in the battery cell cavity on the back or side of the remote. Try the $5-$10 remote idea first, and if that doesn't do it for you, consider if your setup would benefit from a big-time "universal" remote, with fancy color screens to show you what device it is currently controlling. Good luck.
P.S. I eventually wrote down the settings for the tv, teh stereo receiver, the cd player, the vcr codes, etc., on a cut-down 3x5" card, covered with wide package sealing tape, on the back of the el cheapo remote, so that I could look at the back, and know that if I was going to use it to control the TV, I had a four digit number written down which, after pressing a certain key on the front of the remote, followed by the special code that transformed the remote into a tv remote ("3145") and then the equivalent of an [enter] key. Then I had a tv remote. to turn the stereo, I would look at the back of the remote, flip it back over, enter a code ("8989") and the channel up and down buttons would let me traverse the radio dial, etc, and best of all, the volume and tone controls are right back at your fingertips. Enter a new code to start up the cd player, skip to a certain song, then turn the remote back into a controller for the receiver, etc. There are probably apps that do this for the iPad, maybe Android devices, perhaps even iPhones or SIIIs camera/phones/mp3 players. Good luck, have patience,as you will only have to do these steps of "code discovery!" once if you have a chart and write down the winning codes)!

Remote control rmt b101a stopped working, changed batteries, same thing; did reset by pressing power, TV i/o and vol- simultaneously, still not working. Help!


Hi,

Make sure that the Remote is operating in a range of 3 to 10 feet away from the unit.
Point the Remote directly towards the Remote Sensor of the Device.
Remove any obstacles that may be in the path of Remote and the Sensor.
Make sure that no interference is blocking the Remote to operate normally. Do not expose directly to Sunlight, bright florescent lights etc.
Try resetting the Remote by removing the batteries from the Remote control, press every button twice, and then re-install the batteries after 1 minute.
Make sure that none of the buttons on the Remote control is jammed.
Install fresh alkaline batteries in the Remote, do not use rechargeable batteries.
Make sure that the batteries are inserted by matching the polarity (+ & -).
Try resetting the Blu-ray Disc Player with which you're using the Remote.
If the issue persists, after all the possible troubleshooting steps, service may be required.

Thanks for using FixYa

I get the following error message when iI press the I/O button


It sounds like the remote and the tv are not completing the signal the remote is sending. Have you checked to see if there is anything blocking the little LED (l.e.d.) in front of the remote?...It could have gotton scratched, or even chipped, in the factory or along the way. Other than visibly seeing any defects with the receiving LED on the tv and the sending LED on the remote it could possible be a programming/ setting problem.I hoped this helped you some!
