SOURCE: we have a sharp lcd

no problem occur on your set but the only problem is you can not lock the fine tuning (in manual procedure) but is it better to set the program to AUTOSCAN OR AUTO PROGRAM and authomatically tune and save to the memory all the program channel

SOURCE: volume control slide stuck on screen nothing in

WS-65809? Unplug set first!

Remove front speaker grill---it should pull out and is secured with pegs.

Behind it you will find an inspection plate---remove the plate---notice the one or two groups of wires coming down from the front keyboard with all the controls.

Follow them to the right behind the inspection plate--you should find one or two plugs---The idea here is to disconnect the keyboard on the front of the set------You will still be able to turn the set on etc with the remote control

With the keyboard disconnected (the plugs if there are two will be different sizes with letters on them so you cannot get them back wrong) plug the set back in and wait about 2 minutes---

Turn it on then with the remote----if set works normally now with the remote one of the micro switches (vol up) on the front keyboard is bad.

You have two choices---leave the plugs undone and just use the remote OR someone has to remove the entire screen from the set and get at the keyboard(it is a small circuit board) to remove/replace whichever tiny micro switch is bad.


Let me know what happens and reply here if you need help of have a question.

No Signal On D/TV


You may lose some channels when you retune the TV as the channels have been rearranged. To locate them look at the EPG although you may still find that some channels are no longer available on FREEVIEW. See the following link for additional information

http://www.freeview.co.uk/_retuneinfo/

If the above process does not work then check the link above for additional information and also visit the accompanying site links below to find more information for your model of TV / FREEVIEW box.

Built in freeview doesn't work but digibox does


Have you done a channel search on both tv sources(atv and dtv). most new tv's will automatically start will "New Install". If you havent had a digital installed recently then this could the problem. set top boxes and TV's will pick up the signal ok but others wont.

Dont not pick up freeview channels


if u pick up NON freeview channels, i think the antenna isnt good enough to pick up the signal..freeview requires a very good signal, very important.
If you think this isnt the problem rescan the channels
If you think the TV is faulty contact Samsung directly

Lost ITV channels and C4


I think you need to get Sky because it will give you 100% coverage of all terrestrial channels. You may need to retune the television otherwise just get sky
