Recently, I've had some problems with the center channel of my
RSX-1055 (completely up-to-date firmware). When I run a test tone through each speaker in my system (5.1), all of the speakers sound normal except the center channel. I have to raise the volume on the 1055 to 70+ in order to hear any sound out of the center channel. At 70+ volume, the test tone
through the center channel sounds very crackly and disjointed, not
like the normal steady white noise of the test tone. I've tried to
trouble shoot the problem w/ the following trials:
-Unhooked the center channel speaker and plugged the left channel
speaker wire into the center channel speaker. It sounded fine.
-Unhooked the center channel wire from the center channel speaker and
plugged it into the left channel speaker. So the left speaker should
have played the center channel material - no sound until I turned the
volume up to 70+ and then it was crackly and disjointed.
-Used the center channel speaker wire on a different channel (to make
sure the wire wasn't bad) and got sound.
So, I've ruled out the center channel speaker, sources, and the
speaker wire itself. That leaves me with the 1055. Another item
to note is that when the 1055 is in Dolby Surround mode and I
flip through TV channels the sound varies widely. Some channels I'll
get all of the background music, but no voice other channels I'll get
basically nothing. I reset the 1055 to factory default and tried the test tones
again, still nothing from the center channel.
I opened up the unit just to see if there was a fuse blown. It is pretty complicated under the hood, but the fuses that I could see looked fine.
I don't know. Any thoughts before I send it in for service?
