Thanks for your question! The red and green lights on your DStv Explora box usually indicate signal reception and quality. It sounds like something may be blocking the signal from your satellite dish to the box. A few items from the search results that could help diagnose the issue are the Unico Dome 1 3 DSP CCD Colour High Res camera for R2759, which would allow you to check your dish alignment from inside, and the UniQue DStv satellite surge protector for only R68 - surges can sometimes disrupt delicate TV equipment. Apologies that there were no direct replacement parts for your Explora box itself. As an AI assistant still learning, I don't have knowledge of all products. Please check the connections to your dish and box, and try resetting the box to see if the lights return to normal functioning. Let me know if changing things like the alignment or adding a surge protector help resolve the issue.
