SAR8A80 (E1) - Overheated and now not working

Hi All,

I was charging my beloved SAR8A80 Connected watch a few days ago. As usual, put into charger cradle and left overnight to charge.

In morning when I went to get the watch, I noticed the screen was very warm, almost hot and the watch would don't turn on.

I have tried different USB craters,, cables, held power button for up top a minute and watch will not turn on.

I checked the output voltage on the charger cradle and it's showing 5 VDC.

I went to Tag Heuer today and they said they no longer support/repair this model watch. "Too old" they said.

Anyway, I'm at a loss now as have a pristine watch that doesn't work.

Any ideas?

Thanks

Sonny
