Little help TV related

CAn anyone think of a reason why I have a problem getting Channel 4 on a downstairs television?

I have two Black Diamond TVs identical, one upstairs, one down and the signal booster and splitter box in the attic nest to the aerial. Upstairs I have near perfect pictures including a not too bad Channel 5 but by the time the signal is downstairs( a mere 15 feet) there is no Channel 5 and a very poor Channel 4. I would be very grateful if anyone could help.
Thanks

dodgy cables.......dodgy booster box or booster box connection........the (thingy magigy) that recieves and decodes(possibly a reciever or a decorder?) the signal in your downstairs tv may be damaged or never worked as good as the one upstairs in which case it cant pick up those channels......start by taking the signal directly downstairs with or without the booster box see if that works.....than try putting the cable into a vcr and tune the stations into the vcr and watch them on the vcr channel on your tv, as vcr's are better able to recieve signals.......hope this helps in some way...........

switch tv's to rule out dodgy tv

Thanks folks, I have already tried all of these, The channel 4 is fine with each of these suggestions and I have eliminated the TV being at fault. I must have some sort of poltergeist !

Channel 4 is renowned for being of poor quality. I have excellent quality on all channels except Ch4. The cable length to downstairs is probably just long enough to deteriorate the weak Ch4 signal but not the other strong signals. Its hard to explain. Parents have the same problem on Chorus, I'm on NTL.

second booster box just before the tv or replacing the cable that runs downstairs? both cost money though........it sounds like a balls of a situation alright though

edit/ scratch the new cable idea if all other channels are workin fine than replacing thee cable aint gonna do shiit!

Have you tried a new cable straight from booster/splitter in the loft to the downstairs TV ?

Have you remade the connections on each end of the downstairs cable?

What kind of cable is it? Is it double screened (foil and copper braid)?

It sounds like it may be the cable or connections resulting in some loss. I have seen poor cables reject certain UHF frequencies altogether.
