7-Segment LED Display K8089

Hello, i have a problem with a Velleman 7-Segment LED Display K8089. The temperature is stuck on fahrenheit and displays a temp without the temp sensor attached and a fixed temp with the sensor attached. The sensor used to work. I think i’ve narrowed it down to the PIC16F676. Would it be possible to obtain a replacement PIC16F676 for this unit?

I’ve tried changing the jumpers. Removing power and backup battery for hours. And checked the board.

With regards, Gerrit.

Many thanks for the replacement chip, the display works perfectly again. Now people walking past our place can see the time and temperature again !
