Constantly need to be reset - cause?

文本:

I was looking at doing a battery replacement on a pair of Beats Studio 2.0 headphones that I picked up not working, but it looks like the problem is much more technical than a battery issue. It is as if the pair of headphones constantly "freezes", requiring a hard reset (ie. press and hold power for 7+ seconds), often which follows with a 1-5 second proper function before "freezing" again.

By simply pressing the power button or plugging/unplugging the headphone wire, it blinks a red LED 3 times, although this does not always happen.

The battery voltage is rated at 3.7v and is supplying over 4v at full charge (which is normal/healthy) - this is how I'm sure it's not a battery issue.

The length of time "working normally" before re-freezing seems to be larger when the headphones have not been used in a while... this may be a hint as to which part of the circuitry is malfunctioning

Apple (who owns Beats) quoted me on a repair for $215 CAD which seems high. I'm hoping that someone who has some circuit board repair/diagnostic skills will be able to solve this problem which seems to be plaguing many others.

Hi-res circuit board layout is available if the attached images end up getting scaled down. I'm not great at reading circuit boards, but it looks like there's likely more circuitry in the other side
