Hi

Hi
the di4001sets it's net id automatically
either net id or freq are wrong..or your signals low,remove any splitters and check your wiring,basically a signal fault.

looks like the box has taken a prtial update and has a corrupt crc in nvram.
to cure this problem, remove the red jumper for a second or 2 then refit.
do not connect the cable feed. connect scart and hold channel down button while inserting power lead.

this should get you into the eng menu.

now while in there connect the cable feed and check your signal strengths upstream and downstream there are 2 pages for this. both must have a lock.

report back when you have done this.

ok leaves you with having to reflow atmels/nvram and just about every other chip on the board. this seems to be a hardwae fault as it is uncommon for a box to display an NIT timeout error when not connected to cable and you only boot the eng menu as this takes presedence over a netid search. also if the err20 comes immediately also suggest hardware fault.

Thank you m8 for your quick replies as im not much good as far as soldering etc is concerned i think i will put this down to experience and put this box aside should i ever need spares thanks again m8 and the other guys for your replies thanks again
