    One of the speakers worked on and off for about 6 months, now it seems to be completely out, - Other speaker works as fine. I can't even get into the thing to see what's going on, it sounds like a flakey connection to me.

    Does anyone know how to properly disassemble the iM7? I was able to remove the battery doors, bottom panel, side speaker covers, side speakers, and rear grilles, but I am unable to go further. I still cannot loosen the top half of the rear handle panel, the front iPod bay, and subsequently the front speaker grilles. After removing the handle rubber lining the piece seems to be PVC-glued to the main body but I cannot be sure. I don't want to cut apart the unit just to find out that there was a screw or snap I could have removed beforehand. I was wondering if anybody had any experience with taking apart an iM7.

    My IM7 is only 1 year old and everything is working intermittently - I am thinking that something is loose inside. I too tried to take the unit apart and only could get half way. If anyone has experience taking this thing apart could you please post some instructions.
    Thanks

I had the same problem. Eventually the other speaker quit also. The problem was a broken wire under the door. This required complete disassembly of the unit just to get at these two wires. Sorry the news isn't better.

I need to open the casing on a logic3 wip027a ipod speaker system. i have removed all 4 srews from the back in each corner but there seems to be some lind of fixing holding the centre of the unit. how


Hi, I opened a Logic3 I-station today (dark grey and silver), and there are LOTS of screws for each side.
- on the side where the line in and DC adapter sockets are, there are 4 Phillips screws including 3 hidden behind rubber covers.
- you need to remove them all.
- for the other side there are 2 at the bottom and a few more on the back under rubber covers.
- but no more other hidden screws.

Then you need to be BRAVE because the bottom and short side are clipped at the bottom.
- you have to lever the front off quite hard to get the clips to release.
- The side without the DC input came off easier, because it has just a speaker in it (and nothing broke.)
- The side with the DC input connected came off and broker the speaker wires away from the speaker because the speaker cable was glued to the back where the ferrite bead is.

Then you should be in, and see the 2 PCBs on front right and nothing but speaker front left.

Hope this helps.
Regards,

No power of my SC-HC3


I have good and bad news for you. If you have a UK power plug for 250VAC (odd shaped three-pronger), then you should be able replace the small 5 Amp fuse inside the plug (jack) head of the power cord and it will work just fine. That's the good news. If your like the rest of us on the planet, then there is no fuse to protect the power supply from line voltage spikes. Some component of the power supply has been fried... there is no internal fuse as I torn the thing apart, including the transformer compartment looking. Rumors elsewhere talking about an internal fuse in the SC-HC series of Panasonic CD/IPOD players are not true. I had read several myself and believed them to be true, so proceeded with dis-assembly. THERE ARE NO USER SERVICEABLE PARTS INSIDE THESE PRODUCTS. It is not worth repairing. I am an engineer and can tell you that the best thing you can do is salvage the speakers with the grills and make yourself a nice pair of cube bookshelf speakers with them. A pair of 1500Hz crossovers (or thereabouts) and a a pair of screw-in speaker terminal strips from Radio Shack, carpenter's wood glue, wires (red & black by convention), a low-wattage soldering iron, electronics solder, and some planed wood is necessary. The original design is tuned port, bass reflex so to obtain the same sound quality you will need to cut a round hole with an Area of 17.7 cm2 in the speaker box cabinet back. For those using inches, it's 2.54 cm/inch; divide by (2.54)x2, so you can understand the port hole is not very large. You should place the port hole on the back as in the Panasonic design as making the speaker cabinet larger will require a different port size to get the optimum 50Hz tuned bass punch from the speakers. Just cut the wood to form a rectangular cube. Make holes in the front precisely so the speaker grills can clip in around the speakers, make your tuned port hole in the back, and make a small hole to pass wires from the crossover inside to the speaker terminal strip on the outside ON THE BACK (usually near the bottom). You will need to use a hole saw (cheapest type uses an electric drill attachment) or a jig saw to cut holes into the front of the speaker box to insert your speakers flush against the wood face (make a paper template and trace the round circles onto the wood). Connect each speaker to the proper part of the crossover; i.e., tweeter and woofer cone with your wires and solder all the connections, finally, screw the speakers into the fronts with wood screws. Use carpenter's glue to glue the wood pieces together. If you have the time and the inclination, this makes a great family project to introduce recycling concepts too. These speakers will be good for surround sound applications (rated at 40W RMS) or simply used to connect to a small sound system. To use it with a PC, you will need to buy an a stereo mini JACK and carefully solder the wires you extend from the speaker terminals: join the two black wires together (one from each speaker black terminal) to solder onto the long side inside the stereo mini JACK and solder each of the red wires onto a separate prong of the two remaining. This will provide stereo sound by inserting into a PC's headphone plug. For information on how to design and build speaker cabinets, Radio Shack has an excellent (very cheap) paperback on the subject. Hopefully, this gave someone an idea.

How can i open the "jbl on stage 400p" for


We just discovered how to break openthis mother. Use a flathead to gently lift the wraparound speaker cover from the lip, and gently work your way around the speaker. Underneath it you'll find a crapload of screws. Then go to town.

They dont charge my 5th gen ipod wats going on?


Is your AC adapter plugged into the speaker? Your iPod won't charge unless the AC adapter is connected to the speaker and an outlet; the batteries alone will only let you play your iPod.
