Didplay goes black after one photo

My Canon A2200 has stopped working in normal condition; takes a photo, displays image and then display goes black.  I posted a similar question and quite a few people suggested that it was my battery.  I purchased a new battery, charged it and tried it out to no avail.  I contacted Canon USA and was told that a sensor has malfunctioned and unfortunately the camera has reached the end of its service life (no spare/repair parts.)

Does anyone know where the said sensor might be located and what business might stock these?  If there are any sensors out there I could repair my camera.

Thank you
