Please can anyone help i cant tune my tv it wont pick up any channels when i auto tune it it says weak or no signal but i plugged aerial and tuned another tv and its fine

Could be a tuning problem. Try retuning the set. Make certain you are getting the strongest signal.

It could be a signal strength or signal quality problem - too strong a signal is as bad as a weak signal.

Retuning using a different aerial with a known performance would prove that. Once retuned with all channels present and stored in the memory you should find the original performance using your own aerial is restored.

You can't just tune the new channels on most Tv You have to tune the whole set, go to settings select D T V and ok. If you have done this and still have missing channels the signal me weak, you may have to buy a high gain aerial.

The make and model please

Well, there's your answer then. You have poor aerial signal so the TV cannot lock on when tuning. You need to sort out the reason why there's "Poor or No Signal" You need to fix the aerial, not the TV. I would have thought that was self-evident, surely?

What kind of aerial are you using. Do you know it works? Check out the aerial cables for breaks or badly fitted connector plugs.

hi your signal could be to strong, on the aerial cable the thin brad rap 4 strands around the center solid pin then retune in auto, if this does not work you may to manual tune it in, or get someone to check your aerial and you could try a firmware update on your tv hope it helps

Try going into your settings in the tv and try changing were the signal comes from and manually 're time sometimes works in pore signal areas and moving the aerial may help

if it has freeview built in its usually programmes itself try turning it on and go into the menu and there should be an auto tune function hit that and it should tune up but remember it needs to be connected to an aerial if it still says no signal try moving the aerial, getting a booster for the aerial they usually plug into the mains then into the back of your tv and you plug your aerial into that to boost the frequencey if that doesn't work then you might need to think about getting a new aerial but you can get 1 for under £30

The most likely problem is the aerial system you are using in your new location. It could be either the position of the aerial needs to be adjusted or the cable coming from the aerial has a problem, check the end connector that goes into the Tv to make sure it is wired correctly. Also check with your new neighbours to find out what quality of reception they have, it's possible you may in a "weak" zone for picking up a freeview signal.
