Ian Holmes: Judging by what you have said as far as tests having been carried out are concerned, this could well indicate that the box has developed a fault, as Sky boxes are notorious from developing power unit problems associated with leaky / dried out electrolytic capacitors. However if you haven't already done so, then you should also carry out an LNB check as per the following procedure just in case the settings have been corrupted, as your external signal meter will indicate a signal irrespective of what they might be set to. (These instructions are dependant on the menu system used on your particular box) 1:- Press Sky followed by "Services". 2:- Highlight System Setup and press Select. 3:- Press 0 then 1 then Select and the installer menu should then be seen. 4:- Press select again to access the LNB setup screen. 5:- Press the "Red" button to re-set the LNB's default settings. 6:- Using the up/down arrows, highlight "Save New Settings" and press Select. 7:- Press Select to confirm that the settings have been reset. The correct settings are / Low frequency - 9.75. High Frequency- 10.60. The LNB power supply should always be set to on. The 22KHz Command should always be set to on. After completion Press Sky to return to normal viewing. It may take 60 seconds for the picture to appear.

nnenna: Please refer to a reply made to Ruth @ 4.53pm today, as most of the content is also applicable to your problem, although "if" you have been using the same box for a lengthy period of time then the box itself could have developed a defect in its power supply, this in practically all cases being the cause of these boxes breaking down.

Keith Gee: Leaving the box unconnected for that period of time should not result in what you have reported, and so you should double check to make sure that the mains connector on the rear of the box is fully inserted into its socket as the light you refer to should come on irrespective of anything else.
Of course it has to be said that Sky boxes power units can, and do fail, as these boxes in common with many other transistorised devices that run permanently warm by being continually powered up (albeit in standby) can fail if allowed to completely cool down, but though only "if" any deficiencies existed in the power supply to start off with, and so should the box still fail to come on after having checked the mains connection then what I have just mentioned could possibly apply.
If you have another mains connector lead you should try the box out using that, as this type of lead is commonly used by a multitude of devices such as laptops / camcorders power units etc,etc.

griff: If by "allowed" you are inferring that you are within 12 months of the installation having been carried out then purely in the "technical" sense yes, but I would hold onto the existing LNB just in case some problem arose whereby you had to contact Sky, as you could just refit the old block for purposes of the engineers visit.
By the way, if you are intending purchasing a Freesat twin tuner PVR (recorder) then you would require a quad LNB, although even if you are only intending to purchase a Freesat receiver and not a recorder its still best to purchase a quad block, as the price difference between both is negligible.

Sandra: Someone might be able to offer an explanation if you had cared to mention exactly what the no signal is on, e.g: Sky - Freesat or Freeview.
And should it be "Freeview" then your post code (or one from nearby) would also be required, this not being necessary if Sky or Freesat.

Chris: TS10 is not really sufficient enough for a reasonably accurate assessment to be made of the signal level expected at your location, however if you cannot receive Dave then its most likely because you are picking up your local relay station of either Guisborough @ 4 miles 187 degrees or Eston Nap @ 4 miles / 209 degrees these "not" transmitting commercial channels by being PSB only relays.
If you have previously received Dave then it must have been from either Bilsdale @ 17 miles / 190 degrees or Pontop Pike @ 33 miles / 302 degrees, and so without knowledge of where your aerial is facing nor at what angle its mounted at (horizontal or vertical) you should try a "manual tune" scan on first of all Bilsdales COM5 / ArqA Ch46 and see what comes up, if nothing then try Pontop Pikes COM5's / ArqA Ch59, these being the only two alternatives to your local relay, and which you may or may not be able to pick up dependant of aerial direction / mounting angle. (H or V)

Malcolm: Malcolm: Basically yes, but if you are receiving from any of the two Eastbourne relays then you wouldn't be able to receive either ITV3, Pick TV or Film 4 either as these do not transmit from any of the two relays mentioned.
As Heathfield @ 14 miles / 353 degrees (horizontal polarity) is shown as your main station then (menu allowing) you should carry out a "manual" retune on Heathfields COM6 mux Ch41 and see if anything is received, although its very doubtful if it would be if the communal aerial has been vertically mounted to cater for reception from the local relays, this being something that maybe you could send an update on.

Malcolm: Just out of curiosity, when you say that you can receive most other channels well does these channels referred to include ITV3(10) or Pick TV(11)? because if as Dave Lindsay has mentioned you do reside in the block with garages under the residential area, then the roof mounted aerial does indeed point in a Northerly direction towards Heathfield.
The other point is, that when you were carrying out the manual tune did you see the signal strength being indicated "before" you pressed search or scan, because on most TV's / boxes you can, and is something which gives a good idea if the signal is actually there but is sitting at just under the reception threshold, as in most cases where this situation applies then its usually cured by the addition of a booster in line with the TV or boxes aerial socket.

Phil: Its not really easy for anyone to offer advice on your problem without knowledge of your location, this in the form of a post code or at least one from nearby, e.g: a shop, because if its only the Humax that is causing problems then this could possibly suggest that the signal received might be slightly too strong, as Humax devices (all types) have one of the best tuners around thats known "not" to glitch in situations where others will.
I would normally have suggested to try a test by-passing the aerial amplifier, but "if" you are using the type of aerial with the amplifier as part of it (albeit an excellent device) then this test is not really possible.
Further info can be supplied once your location is known, as this will enable access to the reception predictor.

Sandra Richards: Please refer to the reply made to Ruth @ 4.53pm, as the contents of also apply to your own problem.
By the way, although that your Freeview reception might well still be OK, this is simply because the lower radio frequency signals used by Freeview do not get blocked in the same way by heavy clouds as do microwave signals as used by Freesat or Sky.
