Caution, the re-assembly is much more challenging than the dear-down. Masking tape (to temporarily hold the screen and func. set dial assembly in place while attaching the ribbon cables), tooth picks (the ends fit nicely in the ribbon cable holes) and a small plastic putty knife (for raising cable hold-downs) nay come in handy. You will find that the camera face has a ribbon cable for the control ring. When reassembling, note that there are anchor nobs over which holes in the cables go - front side of camera. Reinserting the func set cable under the control ring after attaching the screen cables is difficult (tight fit). Try inserting tooth picks to make room. My new screen cost $30 from D H Cameras on eBay.
