Sennheiser EW300 - Water Damage Teardown

[@sqatto]

Wow! There’s water damage and then there’s ‘left at the bottom of the ocean’ water damage

Ive actually repaired a few of these in a very similar condition a couple of years ago. Eventually got them to work. had to make a few jumpers on the damaged traces.

This is mental....I have 3 of these , 2 that won't even power on and they are immaculate....they have been stored for about 5 years but were working when stored.. without batteries. I've got One in bits on my bench and literally can't find an issue...well not anything obvious....and you say these turn on.... I must be so unlucky ...... Currently chatting to Sennheisers to see if they can be fixed. I did notice blue corrosion on the battery terminals but as I said they weren't like that when stored and I religiously take batteries out after every performance..So annoying as they a bloody expensive to replace...got any tips of things to look out for....my third one works perfectly...go figure.....

Sonic screwdriver time :)
I'd risk using a lot of isopropyl alcohol and try reviving the poor thing, even if just out of plain old scientific curiosity.
