Hi, I have a almost 10 yr aerius. But I think the both the panel is spoilt as the sound emitting from the panel is softer and softer and now I can only hear faint sound for the panel. The woofer sound is "BIG" in comparison. Agent advise to replace the panel, but it would cost a bomb! Anyone try reviving the panel? try using a vaccum cleaner to suck the dust. only helps by 1% - 3% only. I live in the tropical region, thus the humidity and dust caused it. Help is needed here or anyone have been DIY repaired the panel like cleaning with "distill water"? Thanks in advance.
