|Hello guys, thanks for all the help. Your postings have proved to be useful to many people.|
I will now present a problem and I hope that some of you might know the solution from past experiences.
My speaker is Altec Lansing ADA890 THX Certified (4.1 speakers) and my soundcard is Creative X-Fi. It all started when suddenly it stops producing sounds. The power LED on the subwoofer is green indicating there is power in the unit. One strange thing that I noticed was the reading on the LED display at the front speaker (where you can control Volume, Bass, Treble). Normally it reads STEREO, STEREO X2, QUAD, PROLOGIC (depending on your preferred sound setup). Now it reads DOLBY DIGITAL HD (blinking) but with no sound. I unplugged the wire connecting it to the soundcard and plugged it onto my MP3 player and it still detect DOLBY DIGITAL HD (still no sound).
Can you all give suggestions on what might causing it to behave that way and if possible how do repair it? I have been trying to find circuit diagram for this speaker but to no avail. I already bought a 2.1 Klipsch Promedia but I still like the sounds from my Altec Lansing and I really want to have it in working condition again.
Play it safe!
