I have a Samsung LE32R738D and a few weeks ago we lost all but one digital channels and four analogue channels. the digital channel (BBC1) that we have is frozen. On DTV the D.MENU option is not available and the Plug & Play menu is greyed out. I have tried to reset using TV on with Remote/Info/Menu/mute and Standby but do not see the Service Menu I expect. Can you help me please?

just spoke to Samsung support and it turns out that the freeview tuner had froze and needed resetting. To do this put TV on standby and then push in series these buttons on the remote: 'info, menu, mute, power' the TV will then turn itself on and display a menu. Press the 'down arrow' untill you've highlighted option 12 - 'reset' and then press the 'right arrow' to enter the option. TV will turn off and when you turn back on it will start in 'plug & play' mode as if new. Set the time and country options and then it will perform a complete scan. I've just retuned mine and all back to normal. Hoorah!!!! :-)

This is very common to a number of Samsung models built at the same time as yours and using the same in-built Freeview receiver.

There is no fix, the built in receiver is simply incompatible with the most recent updates to Freeview (as happened to many external boxes) and cannot be modified, the only puzzle is the length of time that your receiver kept going for. If your tv has a warranty still then you may wish to see if the fault is covered.

Without a warranty, all you can do is continue to use an external Freeview receiver. They're usually better quality anyway, and are easy to replace when they go wrong or become out of date.
