So I purchased a M28 in August of 2017, I received the unit and it would not record any dive data. It seemed to be frozen with the data from Poseidon's testing. I returned to Sweden and that issue was fixed around this time last year. Now, the unit will not boot up. I have meticulously charged the unit to 100% every month (as recommended in the manual), but when I try to turn it on I get 10-20 green flashes and 3-5 red flashes with a blank screen. When charging I get the same lights, nothing boots up and now it does not seem to charge. There is no possibility of water intrusion or other damage. Any thoughts or similar issues? I've reached out to Poseidon, just checking here while awaiting a response. I've loved my Poseidon gear, but have had no luck with this piece of equipment. Thanks.
