hi what i have found is on the can where the feed goes it there is a black wire which goes from can feed to the tv can the cable has come lose in fact its come off could that be my problem to why im stuck in tune? the wire seems to be like a pin so ive plugged it back in but still no luck im a lady and im not good at opening boxes and getting my hands in a tangle jimmy has spent days on end and showed me how to do my card, i hope there is an easy way to this problem.
remove any splitters ect and connect the box directly to the feed that comes into the house. you may have a fault on your cable arrangement (although this is unlikely)!! otherwise you will be left with the stuck in tune guide and looking around your upstream tuner curcuit.
what splitters i have connected the wire into its feed my other box doesnt have a problem that works fine its the 4001 that is giving me problems getting into the eng menu is no problem but i guess there is a shortage to where the main feed connects to the box ,im getting tired now.
it is entirely possible for a splitter to be faulty on a single output
it is also entirely possible for the splitter to be reducing you available signal below 16db (the minimum required for a 4001 to obtain a netid)
your other box is a 4010 and this only looks for a netid when it is first installed a 4001 looks everytime it is power up.
also the threshold for 4010 is 25db downstream and the 4001 is 27db.
bottom line your 4001 is older, slower and not as well made as the 4010.
bit like myslef really LOL.
by all means ignore my assistance as i said it would be a long shot and most likely you have a hardware fault.
