Background
: Moisture or dirt has accumulated between the Lenticular and Fresnel
screens. The Tint screen consists of Lenticular / Fresnel screens, these two screens
must be separated and cleaned.

models is not. Panel must be separated by carefully pulling seam apart. (Model
PCJ534RF has this type of design).
b) Remove Tint screen, screen is supported on four sides by metal brackets.
c) Remove tape around Tint screen. Save tape, if new tape is needed use black
cloth tape, not electrical tape. Separate Lenticular / Fresnel screens.

f) If problem is still present, replace Tint screen.
