f5 box problems?

[utdman]

f5 box is not dead but no graphics/picture/sound on screen. connected another skybox f5 to tv via hdmi and all ok but when connecting the previous one i get zilch.

will i need to reflash with null modem cable?

Have you tried it with scart only? Possibly your hdmi port is knackered

did not try a scart...hdmi ok as i tried another box...

all ok now after a reflash via null modem cable
