in fact it is all green, a very bright, but lucid green, and when you squint slightly you can make out waht is on the display. i re-seated the cable and wiggle the cable about and nothing changed. Sadly i don't have a spare screen. So my next question would be one of compatibilty. Which screens can i use with the 750c? The HMM lists the 355, 750, 755 etc all together but are the screens interchangeable?
