Home Theater Questions? Ask a Technician for Answers ASAP
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, is this a fresh/new installa? ...or has it been in used with the center speaker working with this issue just recent?
Settings and connections were not changed?
Have you checked the rear of the Pioneer? ...speaker? ...its wires please?
The settings would largely depend on how the Pioneer was initially/previously setup. If nothing was known to be changed, then perhaps you may want to consider / try a RESET. A reset would serve as both a test and an attempt of a fix.
Please post back how you would want to approach this and/or should additional information be needed.
As posted above, reset is both a test and a try of a fix. As it implies, a reset would force the unit to revert back to factory defaults removing glitches and config errors but would include memories, presets and user preferences. After a reset, the initial setup would have to be performed. If have not been done and should you venture to try: please click HERE.
May have to be done a number of times.
This is very critical - a reset however would not be corrective of an internal hardware concern; but it would be confirmed. In some instances, it may even expose other issues.
