You might want to talk to JVC as this model had all kinds of issues--missing any color, picture inverted or backwards just to mention a few.

The solution was to connect it to a computer and use a jig from JVC and download two up grades on sd cards and install them manually.

I mention this as the Light engine in the set communicates with the main chassis and you in fact may have a issue with that.

At least make a call to JVC---saw about 40 sets with this model where this cures all sorts of communication issues--the engine if "set" wrong could easily cause this problem.
