Question about Wurlitzer Rock-ola Jukebox

1 Answer

Nostalgic Bubbler gripper assembly seems to be out of alignment and isn't picking discs up or removing them correctly and/or at all.

I found that the arm is picking the CD from the magazine improperly. When it sets the CD on the CD player, it's about half an inch out of alignment. The clamper plate then forces the CD down. When the gripper then tries to remove the CD after a song is over, it doesn't align correctly and does't remove the disc at all.

C key is sunken down. The hammer action counterbalance isn't working properly

Check it again. It may have something dragging on the key, maybe something sticky like soda or juice residue. You can also try swapping out the key with another C or F key that is less used. Good luck!

With the correct power will my TV & Surround system work as a streaming device in the Uk. I understand that the network would not be available?

Not sure what you are trying to do. If you use an appropriate power adapter they will turn on but (assuming your equipment is not euro market) Europe uses different signals so they won't pick up any channels. You would have to have a seperate device to tune the channels and convert it to you non euro tv signal requirements. Also if your sound system is your dvd player only discs encoded for the same region as your dvd player will play.

Yamaha keys g and c# don't work

You didn't describe your problem with enough details. If the keys operate mechanically, then the problem might be with the integrated switch assembly. You will need to disassemble the entire case enclosure to check the key assemblies. The keys are assembled into sets. You can remove the set with the bad switches and replace the entire group. In some Yamaha models you can replace individual switches ( entire key mechanism). You can also test the switches using a multimeter - simple continuity test.
If your keys are inoperable mechanically, ( won't move or move partially) you will have to disassemble the entire unit to identfy the problem. It may be a simple alignment adjustment or a broken pivot joint. You won't know for sure without removing the internals by taking it apart.
Yamaha has excellent service reps (factory trained) either in repair depots or available for house calls. Go to their web site enter your zip code to find the nearest rep. If you are not comfortable taking the keyboard apart, that is the best solution.

I have a Gemini CFX-50 dual cd player. The left tray is not reading the cd whenever I put it in. I am getting a message "no disk". the right tray works fine. What could be the problem? Please help!

If the motor is spinning the disc, then your problem is with the laser. It either needs to be cleaned or replaced. Cleaning can be done with a regular laser lens cleaning disc, available at any store that sells electronics. A replacement lens assembly can be picked up at any store that specializes in electronics.

There are different digital formats and some are not compatible to transfer file names... It is frustrating isn't it?... run into this all the time.

DVD Recorder MODEL no.DMR-EZ27EB has U99 on screen unable to operate it


U99 is a general communication failure between processor and timer, and there may be different causes. Common cause is a defective disk. Removing disk from the drive sometimes may fix the problem.

The first reset that you can attempt is disconnecting power for two minutes.

I quote below a post that was originally published in the MyCe forum (here):

"According to the service manual the U99 error is specifically a "hang up" displayed when there is a communication error that has occured between the main microprocessor and the timer microprocessor.

With more than twenty Panasonics (including four DMR-ES15 models) I'll offer my own observations:

There can be any number of causes for the U99 error, including a culmination of reading, writing, finalizing errors--sometimes appearing after U61 or U88 reading errors. The U99 error might also be associated with unusual DVD Drive noises, "grinding" indicating a dirty rubber hub and spindle; "clunking," "chugging" or "errrp" noises indicating a dirty lens or a failed laser assembly (the "optical pick-up").

Initial remedial measures include the routine DVD Drive lens, rubber hub and spindle area cleaning described in other CDFreaks/MyCE and AVS Forum threads. If that does not correct the problem(s) laser assembly or DVD Drive swapping with a direct replacement may be indicated. Also check for a disturbance to a ribbon cable or ribbon cable contact, correct or repair as necessary.

If the Digital PCB has become problematic, model-specific replacement is indicated. If the DVD Drive on-board contoller (if so equipped) has become problematic, model-specific replacement is indicated. In most cases "model-specific" means the same model year DVD Drive and, with problematic Digital PCBs or DVD Drive controller boards, replacements should be from the same model year and the same or very similar model recorder. Laser assemblies should only be replaced with the same model, i.e., 3331A and 3332A "optical pick-ups" might not interchange satisfactorily.

The U99 error may also be displayed when inferior media is in use. (Beginning in 2008 I've used nothing but Taiyo Yuden 8x Premium Line DVD-R media in my Panasonic, Philips and Magnavox DVD Recorders and HDD/DVD Recorders.)

The U99 error may also be displayed when there is an operating system "time out" occasioned when the user attempts to move too quickly between digital and analog channels (in 2007 and newer EZ series models)."

My pedal is not sustaining - it is plugged in at the pedal outlet, not sure what else to look for?

The first question is has it ever worked? If this is new, the connector of the pedals is a mini DIN type which is REAL hard to get seated properly. Often something blocks it from seating fully. Remove the plug and with a bright light inspect the pins... they are EASILY broken off. Aligning the connector carefully and making sure it seats is important. This piano also has a foot under the pedals to screw down against the floor but that isn't wht cause the pedals to not work.

Ok, we just picked up a double french horn for my high school. It seems clogged or blocked. He pulled out the slides to find where the stoppage was and found a part of the horn in the later part that was...

You haven't described what the part was stuck in or what the part itself was. If the part is stuck in one of the tuning slides I would advise not trying to remove it yourself as it could get stuck worse and replacement parts for French horns are not cheap nor are they easy to obtain. If you do try removing it you risk bending the tubing out of alignment so that the slide won't fit back in and be adjustable. You also risk distorting the shape of the tubing at either end which again has bad consequences. That being said if you do try; try to push the part out gently in the direction you think it entered. Use a flexible cleaning tool like the ones for cleaning trombone slides. It looks like a small diameter plumbers snake with a brush on one end and is often covered in plastic to protect from scratches. Use a gentle tapping action with the cleaner snake against the part inside the tube. If it is still stuck in there try to obtain a ball bearing that will easily roll through the tubing but is larger than the part so that it will not get jammed against the part. Drop it into the tubing. Next drop another ball bearing the same size into the tubing from the same end so that it rests inside the tubing against the first one. Hold the tubing in the hand you use the most with your thumb over the end of the tubing that has the bearings in it. Remember you are trying to remove the part in the direction it entered. Next shake the tubing so that you can feel one bearing hitting the other. Do this gently at first. You are trying to make the impact of the second bearing against the first force the part out of the tubing. Also remember that I recommended against all this in the first place. It took me ten years of experience before I got good at it. This is not normal but can happen. Usually it is a foreign object left loose in the instrument case that is the cause. Make sure that the part wasn't originally soldered to the instrument as it will need to be professionally soldered back on. Here is a link to a professional band instrument tool supplier: Have a look at the tools and you might get some more ideas. Look in Tool Instructions. Good luck.

I just fixed my CDP 100 which had a similar problem - dropped and two keys not working up one end.
1. Lay keyboard upside down on soft surface. Under keyboard is plastic cover held on by 17 screws. Remove all these and lift cover away. The metal key ends are all revealed.
2. Locate the disloged keys. Carefully press them back into position - they will "click" into place. Make sure the corresponding key on the keyboard isn't stuck in an "up" position - you may have to remove the metal key part and replace it again while making sure the key is correctly seated.
3. Replace cover and screws.
