Speakers

[rich97]

I am having a problem with my right rear speaker -- the LED is flashing red and the troubleshooting provided in the Logitech troubleshooting guide didn't work. I was wondering if Mike_M could explain how to do the following from this post.

Did you try plugging the power supply from the working rear speaker into the non working speaker?

Thanks in advance.

any chance this question could be answered by a Logitech rep?

Sorry to join in but I am having exactly the same problem only its my rear left speaker.

Red (only) brief flashes from the LED.  The manual doesn't list this in the Wireless LEDs Troubleshooting table.

Can someone from Logitech could help as well?

Thanks.

Me three!  I've got a X-5450 with the same issue.

Back just before Christmas I noticed that the surround effect was gone and discovered that the left rear speaker wasn't working.  Shows a flashing red LED about once per second.  Tried unplugging it and waiting a while and replugging it into the power - no change.  Tried to re-sync the rear speakers with the control unit.  Re-syncing the right rear worked fine but for the left rear - no change - still flashes the red led about once per second.

Up until this point things worked flawlessly and I'd really like to go back to that surround nirvana....

My Z-5450 is two weeks out of warranty and the left rear speaker displays a blinking red LED. Has this mystery been resolved by Logitech? I need my surround sound!

Update 2/9/2009 - Warranty provides replacement with a Z-5500. Logitech does not repair or replace the rear wireless speakers. You send in the Z-5450 control unit and fax them your invoice or receipt.  I'm opting for the Z-5500 though it has wired rear speakers and only one optical interface rather than two.

There's only one optical-in on the z-5500? OK, it's not possible to listen to two different inputs at the same time anyway but that's ridiculous.

[MrJoe]

I'm not sure what's ridiculous about having more than one optical input. Both my computer and TV (which has HDMI input from a satellite receiver supporting Dolby and an Xbox 360) have optical audio outputs and with the Z-5450 it was convenient (and provided all the benefits) having them both simultaneously connected with the ability to select an input with the control unit or its remote. Since I don't have digital coax output on my computer sound card, I now use the 6-Channel Direct Input (also simultaneously connected) and, obviously, still have to select an input.

The replacement Z-5500 showed up within one week of their receiving the defunct Z-5450 and I now have more wires snaking around my media area to the wired rear speakers and the substitution of 6-Channel Direct for the second Toslink. Kudos to Logitech support for their timely processing of the warranty replacement.

I was agreeing that one is not enough... sorry that you didn't interpret my post as such.

Today I discovered this particular problem with my left rear wireless  speaker. I searched around on the net but did not find the solution. I quickly located the problem to be inside the speaker and not to be in the control unit or the main unit.

So I decided to try to open the speaker to see what the problem is. This was the first problem, how to open the thing. Again an internet search and again nothing. Putting all things together reading about removing grids, heating glues and removing screws.

First pull off the grid from the front, then remove the 4 screws that are holding the speaker assembly into theouse. Pull out your hair dryer or heat gun and heat up the sliver colored strip around the speaker assembly.

This will melt the glue and the speaker assembly will come off relative easy when you grab at the silver strip.

Inside you will see at the bottom a power supply and fixed to the back the wireless unit.

Having an enormous experience with repairing power supplies, I suspected a leaking electrolytic condenser in the power supply. Without any measuring equipment these are often easily identified by the house being deformed from the normal or that the housing is cracked at the pressure relieve slits in the cap.

So indeed I discovered one capacitor that did not look healthy. It sits in the left back of the power supply close to an integrated circuit

beside another capacitor. The value is 100 microfarad 10 Volt and is about 3mm wide and 10mm high.

I took it out and replaced it with a condenser that I had lying around of 47 microfarad and 16 Volt assuming that the value would not be that critical.  Beware of the correct polarization, the minus connector points to the front of the printed circuit when you look into the unit.

I connected the power and immediately the blue light came on and sound was coming out of the speaker.

hamishi,

My rear right wireless has just gone (red flashing light issue) the unit is just over 2 years old and out of warranty, I'm not an expert on power supplies, I have opened up the speaker as you suggested but I cannot see a sign of any damage to anything.

Logitech have no replacement parts so I am left with a useless system, they offered a 50% discount against any product on their site but that is a rrp and still really expensive when all I want is a replacement speaker.

Is there a replacement power supply that can be fitted?
