My 2 year old Ultras just stopped working yesterday. I read all the information here and on other sites. Some misinformation exists and other information is not available.
I called Klipsch Support this morning and they were very sorry and very helpful. Unfortunately my unit is out of warranty and this is what they said.
One Year warranty on ProMedia Ultra 5.1
First Step: Check the power fuse..........
Behind subwoofer, remove panel with all connections… (the Amp module). 12 screws.............
Carefully pull panel out via top left corner and bottom right corner................
You will feel resistance as wires are pulled. Ease it out carefully and then disconnect 4 wires from the two subwoofers using the quick connects, note the wire arrangement for later replacement. (Do not try to disconnect wires from amp side).........
Observe the power cord on the inside of the amp panel to locate the fuse on the right side of the power wires.............
The fuse is a Slow Blow 5 amp part # 270-1067 (get one at Radio Shack)..............
Fuse might not look blown but replacement is recommended to be sure. Install new fuse and reconnect 4 wires to subwoofers. Reinstall panel with 4 corner screws and reconnect all components...............
Turn on power to unit (with no music) and listen for any sounds from sub to determine if fuse may blow again. If no unusual sound was present turn on music from the computer to see if unit works properly............
If fuse blows again Amp module must be returned to Klipsch.............
If fuse is not blow but unit still won’t work return Amp module to Klipsch...............
If everything works again, install remaining screws and count your blessings.............
To return amp to Klipsch: Call first, setup case and get RMA #. Cost will be $60.00 plus shipping to Klipsch. They will return in 2 weeks postage paid............
Hope this helps others.............
