To deal with the problem you must clear the channel list completely and then rescan - if your box has it in the menus, please the 'installation menu' to do an initial scan or a reset to factory settings or First Time Installation. You MUST delete the entire existing list of channels. On most boxes this technique can be also be used:
5) do a complete scan for channels - it will fail without the aerial. (This may be in the installation or initialization menu, and is distinct from any 'add channels option'). Once this is done your channel line up should be empty;
6) reinsert aerial by reconnecting to the 'RF in' connection;
The Freeview channel line-up provided by six "multiplexes" - each of which carry five or more TV channels, radio channels, text services and EPG data. In this diagram each ROW represents a multiplex. If you are still missing a whole multiplex (ie everything on the row) you may need to replace your aerial with a wideband type, purchase a larger aerial or you may have interference from a VCR, games console, Sky Digibox or similar.
Christine: Pressing "OK" on some brands of devices can result in the TV or box rescanning to update the programme guide, the problem there being, that "if" you reside in an area where programmes can be picked up from more than one station? your equipment has possibly tuned into the one with the weaker signal.
You should try carrying out another retune as this "might" rectify the problem, if though it doesn't, then your reception possibilities can be checked if you indicate your location, this preferably in the form of a post code or one from somewhere nearby, e.g: a shop / post office.
hello can any on please help , my gf bought a humax free view box .but after a few years she is getting the green screen problem...its a b .....pain .i had one it also did the same but i sold of it,,,,these should have not been put on the market ,,they were a nuisance when the came out ,, cus humax new there was a problem ..i dont know how they sell these products now,if some one can tell me what i can do with it without factory reset i would be very great full thanks
m.whitbrook: Actually, Humax is a best selling (and excellently reviewed) brand - the only PVR's we recommend at work are Humax's and Panasonics. Yes, there will be some problems, but since they greatly outsell any other high quality PVR brand, when there is a problem, your more likely to hear about it.
Basically, the HDMI's are not handshaking properly. Known as a Humax thing from a couple of years back (although I'll have to ask tech support at work, since its a new one to me), and there are a couple of workarounds, including upgrading the software, swithing on the Humax before the TV, etc.. Easiest thing, swap around the HDMI ports on the TV and see if that cures it. Scart works fine.
