T-Priv Button fix? Plus button is broken

So my T-priv has had the plus button broken for a while, and usually gets stuck at 220 watts, because of a constant input. everynow and then it stops registering and I’m able to turn it down. ive refreshed the software, and tried to take apart the mod to get to the button, but there isn’t anything I can do with my limited knowledge. any help or possible fixes? I haven’t seen anyone else with this issue and would love some input.
