Hi, I got a new Skybox F3 from ebay. I put aj's latest channel list on and I think it's March 2013 firmware. It was working on day 1 but today (day 2) when switching the box on, the lcd counts upto 100 and reboots. Tried loads of times. I took out the sky cable that comes from the dish and the box boots fine but obviously no signal. I have another box running the same firmware without any issues. Any ideas or should I just change the firmware or send the box back for replacement.
