Just bought new Ferguson F2408LVD3. Can't tune ITV stations and a few others. HELP, got to tearing hair out time

You need to do a Full Factory Reset tuning rather than just a rescan.

Rescan simply looks at the place holders where the old channels were stored and refreshes them. A Factory Reset (A.K.A. Shipping Condition) wipes the channel memories and starts again fresh.

If that doesn't solve it then it could be a problem of too much signal on certain strong channel groups (BBC and ITV). Your aerial is more sensitive at some frequencies, so there's more signal power higher up the frequency range. If ITV has been moved to where the aerial is stronger then it could be oversaturating the tuner.

A simple and inexpensive diagnosis tool is a variable attenuator. The MA1620 on this page is perfect for that job:
Splitters amplified splitters and attenuators

It will give you a way to reduce the signal level at one TV without affecting the other TVs in the house.

Check this link for details.

If you are in an area that is being switched over from analogue to digitial you might lose channels to do with that. Another reason could be the leads between the TV and Aerial connections. Make certain that they have good connections and use proper screened cables. Some people also have several transmitters around them, some of which have weaker signals than others. Some channels will therefore not appear. Check the box is tuning into the strongest signals.
If you manual retune then find out the frequencies of the strongest transmitter in your area first and set it on them.

mine has done exactly the same and Samsung will not accept responsibility. Anyone know how to fix this??

Weak digital signal. Either antenna or tuner.

in the manual i noticed a note about the active antenna and it should be showing not active when standard antenna is used.i also tried channel scan instead of first time installation which i tried a few times.so i dont really know which worked,just kept trying.

try tuning tv in another room, if it works it is then your cable or socket, try the cable next. If it wont tune its a faulty set.

I used lateral thinking! looked at the instructions for my other matsui DAB radio and worked it out from there. With this Ferguson model you have to find the station you want manually and then press one of the preset buttons (it only has 4 but these are enough for me)

Just bought the same unit but the instruction manual was double dutch. After messing around for a while I managed to do it like this. Whe the unit is set to DAB, Press the Sel+/TU+ or the Sel-/TU- button on the unit (not the remote) until the DAB station displays and then press the Select CH+ button again on the unit. Wait a few seconds while the word "tuning" is displayed and that station should now play. To save the station as a preset do this. When the station is playing use the remote and press the PRG/MEM button once. Then press the number for which preset you want that station to be. The station will be saved. EG to save Radio 1 as Preset station 1, play Radio 1, Press PRG/MEM, then press number 1. After that whenever you press number 1 on the remote Radio 1 will play. Do the same with any other station you wish to save. To save station 10 press the 0/10 button on the remote. To save station 11 press 10+ then 1, 12 is 10+ the 2 etc. Good luck Dopeyemma
