2014 sunseeker 3050 with factory installed rear and side cameras. Cameras work and turn on as designed excerpt for screen display Only showing “snow”. White with gray lines. No picture. Rig was in storage for 3 years (never again, so many problems!). When inspected last year “an lcd bulb was replaced”. RV repair shop went belly up and closed. Nearest dealer 40 miles away. Anyone have this problem?
