Flashing Lights and No Sound

I have had my Logitech mm50 for a little over a year. It work great. Today the two lights are flashing (one is red the other orange). It won't respond to the remote. Pushing the buttons does nothing. Unplugging it does nothing. It won't make sound.

    I've had these speakers for well over a year now and I never had any problems beforehand. However, I tried to charge my ipod in it (I've done this several times before with no problems) and two lights came up. The power button has a solid red light and the other button has a blinking orange light. The ipod still charged but the speakers will not respond to anything else. I tried using the remote and the manual buttons, but it did nothing. Also, I tried to fully charge and then let It blink until it ran out of batteries, but it won't stop blinking. It has been blinking for over a week and nothing has changed.

    I've had the MM50 for four or so months and since last week have the same problem (red and orange lights flashing; ipod charges but battery doesn't; no music playing). Does anyone have a solution? Please help. Thanks!

    My speakers just started to blink also. have used them for about 2yrs traveling and had no problems. Trying to contact them.

    I've had the same problem. Suddenly, after 2 years of faithful, flawless service, the speakers refused to make a sound. I tried everything, including plugging into other outlets. Nothing. So I got a used one on Ebay-same model.
    That one was sent w/out the power cord so I'm using my old power cord but everything has been fine until today. Suddenly I put my ipod on, it shows that it's playing and charging but I can't get the speakers to "turn on" or make a peep. On a whim, I took out the old unit and plugged it in and suddenly-IT'S WORKING!
    I can understand that the battery stops charging after awhile-that's a ripoff that it isn't easily changed but whatever I use the cord most of the time anyway but the speakers refusing to work? It's weird.
    I'll keep using these as long as I can get sound but being that Logitech has been less than supportive to others on here, when these finally die-I'll be purchasing from another company.

    Exactly the same problem. We have two of these units and both have served us well until today. The one in my office worked fine yesterday but today -nada!

    Might play with the battery but perhaps a new docking station is in my future.

I am 100% sure the battery is dead.
Opening my mm50 I find that the small 2"X 1/4" battery is attached to the back, very near the charging socket. The battery is connected to the circuit board through a small plug-socket arrangement - no soldering here like iPod. So, it would not be difficult to replace it by a DIY enthusiast. But it would be difficult to find this non-standard replacement battery. Better leave the job to Logitech service, they'd would certainly replace it on charge basis.

I know I am a little late but I found a site that sells the NTA2335 battery for the MM50 that you are looking for:

I hope this helps anyone else that stumbles upon this with same issue.

Logitech Z-5450 5.1 surround sound speakers - no sound from rear right only

Unfortunately I have the same problem. As an electronic engineer I suspect that the power supply part of the unit is damaged. I opened up the module (don' t try it, its a little bit tricky since there is a type of glue around the silver bezel, after you remove the 4 screws from the front holes) and did some quick static measurements with a multimeter, so far no luck. Since I am still in warranty I will try to replace the item. Hint: protect your electronic equipment with ups or surge protection devices.

Logitech mm50 very little sound coming from right speaker

Check the cables and see if there is a tear, or unscrew the cover of the speaker (if possible) and see if the contact is frayed or only holding by a couple of wires. This will reduce the sound quality.

If not, the speakers are faulty, and they are not worth replacing. Just purchase a new set.
