Hi guys looking for a bit of help/advice if possible. I have had a Skybox f5s for about 3 years now and it's been working perfect fine up until now (apart from missing the blocked channels) but over the past day or two I've noticed that a lot of the time when I try to change channels with the remote control my box seems to freeze and do nothing. I have to power off and on at the mains to be able turn back on and when I change channels for another short period until it occurs again. Anyone experienced issues like this before? Any help/advice would be appreciated?
