No sound from earpice, only right channel with headphones
I bought a brand new amplifier and plugged in my Galaxy Note 3 as input using the jack port. Since then my phone has multiple issues, but the amplifier works with other devices. Maybe a short high voltage broke something ? Here are the issues :
- no sound at all coming from earpiece (loudspeaker works)
- distorted sound or no sound at all when using the headphones jack. Sound is less distorted when volume is at the max level
- headphones jack will only output sound for the right channel
I tried replacing the headphone jack part with a replacement that i bought on Aliexpress but it didn't work (no sound at all, even from the right channel). So i thought that maybe the issue is with the main board ? Or was my replacement part already faulty ? Should i try again another replacement of the jack ?
Edit: headphones, amp and cable work with other devices without issues. Jack plug is clean with no dust in it. I already tried every obvious solution.
Is this a good question?
