If you have a Bosh gas or electric range with a touch pad above the burners and it stops working.....first thing, remove the top rear sheet metal plate at the back (2 screws) and look and see if the circuit board has come away from the front panel...Bosh uses 2 sided tape to secure the display panel and it can become loose and your oven and clock won't work....
All ya have to do is press it back into place and maybe add some duct tape to the outer flanges to hold it better.....
Good luck..
