F5s load up problem.....help please

[toil levels]

Hi I read the forum everyday hoping to not encounter any problems with my f5s box and pretty clued up on problems but no I have 1 of my own. When I start the box up it loads to 100 and then The 100 stays in the front of the box and goes dim and nothing happens I have to turn it off at the plug and on again for it to load up and come on. Recently I'm having to do this 3 or 4 times for it to load up and come on. Any body got ann suggestions would be much appreciated thanks

So it does work eventually? Does it have the latest firmware?

Yeah works eventually after a few tries seems to be more of a power problem than a firmware. Yes updated to latest firmware
