H....if the camera was dropped resulting in the grab handles being bent after the impact..it has taken quite a blow. The sensors need to be mounted very accurately, and if dislodged even by a small amount....well... you know the painful result.
The sensor is however working.... In which case there may be a solution in having the cover slip removed. See

Given the sensor needs replacing anyway...might be worth a shot.... I'd be willing to do this for you gratis....but give absolutely no guarantee the sensor won't die completely during/after the procedure.
