I have two ST60 GRAPHIC displays that have a hazy cast over the center of the display. I disassembled the display to attempt to clean the back of the screen but it was clear. What is the cause of the haze? Is it correctable? A photo is attached.
Welcome back to the Raymarine Forum Lew,
Unfortunately, the pictured symptom is that of a LCD which is failing. Unfortunately, Raymarine's Product Repair Center can no longer service ST60/ST60+ instruments. You may want to consider replacing this instrument with an i70S Multifunction Instrument Display (MFID). The i70/i70S MFDs may either be installed to support SeaTalk communications or to support SeaTalkng / NMEA 2000 communications.
I'm sorry the news is not better, but thanks for the reply.
