ipod touch: speaker volume quiet with hiss , new ios stuck
A little stumped on this one; 4th Gen Ipod Touch. Replaced the volume/power flex cable – this now works absolutely fine.
However in doing so had completely remove the logic board/battery.
Having put it all back together, playing music out of the external speaker is very quiet, Along with a lot of background hiss (like the sound when you turn up a stereo very loud Along without playing anything).
There is also occasional clipping/clicking on certain tracks Along with lots of high notes.
Playing through the headphones works absolutely fine and at the correct volume.
Ive checked the connection to the speaker itself from the red and blue wires and everything appears to be intact and as far as i can tell theres no grounding issue.
If anyones got any ideas i would greatly appreciate it. I have located this image which shows the board:
