Same here. I've bought a new Oceanic VEO180NX PDC some years ago. It worked fine during a lot of dives, but the display started to go dimmer and dimmer that made almost imposible to read. It was not a battery problem. I wrote to Oceanic asking how to increase contrast, as the computer was working ok. As answer they replied that it was time to change the computer.I will never buy and Oceanic product again. They did such a bad job with this product and were so unhelpful about getting it repaired.
