I got myself a AIYIMA A07 one year ago and was rather happy with it, but recently I noticed a rather pronounced static comming from my left speaker. After doing some testing, I come to the conclusion that it has to be a problem of the A07 L Out:
- No matter what speaker+cable combination i try, it is always the one connected to L OUT that is noisy (R OUT is fine = normal noise level)
- The noise is independet of the amplification power (i.e volume) + only on one channel, so I dont think it comes from the power supply
- The static noise is present even if I do not connect anything to the A07 Audio IN, so it has to come from within the amplifier
A similiar issue was raised by @Blazi3 in the Beginner Forum but it was never resloved, so I thought I try it again in the amp forum (since it is a amp problem i guess).
I would be happy for any comment pointing me in the direction of the problems origin. I was thinking I potentially have to replace/resolder some parts, e.g. the TPA chip or a capacitor? Maybe even the people from @AIYIMA can help me out with this one?
