The telly has been working for about 9 months and all of a sudden without changing anything it is saying there is no signal. Tried switching it off and on and all that but no difference. Analogue channels work.

Re: No signal showing when I switch into Digital mode
Try unplugging the TV and give it a minute or so, then plug it back in. Sometimes the computer inside gets wonky. Completely removing power will reset it, but just turning it off and on doesn't change anything.
If there is still no signal, verify that the source is actually functioning and that all your connecting cables are still firmly in the right places.

So, Vanessa, in sunny Brighton. Has your neighbour got signal problems or is your telly telling the truth? See if there is a receiver problem by trying a portable telly in other rooms. If it works wherever then your telly is in trouble. Have you tried reloading your signal search mode from the handset? If you've brought the telly from another area you will need to retune.
Two things you can try: Check the remote control and press the button for Digital input. Someone may have set the tv to expect an analogue signal from the aerial while you were pouring your wine. Because the analogue tv signal has been switched off the tv won\'t be receiving anything off-air. It will need setting back to digital to receive Freeview.
The television set may be dropping itself into "AV" mode and is expecting an input through a SCART or HDMI socket. Sometimes an external device (video or DVD player) will hijack the television if the set-uphs been configured for this. Try unplugging all external devices (Sky box, DVD, VCR, games console or whatever you have plugged in). Make sure that the telly is configured to digital input and tuned to BBC1. Then see if the it will show the programme. If the television is actually broke then you should return it if it\'s still under guarantee.
freezing is a sign of poor signal , if you connect to cable , try a DVD player if the picture still freeze that mean the TV is bad and has to be returned and replaced. if the picture is good with DVD player as your service provider to give you a better service by boosting the signal
The problem has cleared itself a day later after being switched on/off a few times.I suspect the 'computer part' of the TV (channel processor, instruction decoder etc) received maybe a power glitch or an illegal infrared instruction (2 remotes used at once for example) and 'locked up' leaving just the analogue side operating. I was going to continue happily using it with just the analogue side slaved to my Hd recorder for digital signals but it seems to have got over whatever it was that upset it.
Your problem is definitely the input signal source to your tv. It is extremely rare where a new tv has a tuner signal sensitivity problem. The best thing to do is to replace your current set of rabbit ears with a different set of powered rabbit ears that have a higher gain rating with a variable gain control. Please note that the gain control setting is critical when setting up your tuner for auto-programming. If the gain control is set too low or too high it will result in your symptom.
If you still can't get it to work you could try buying a line amplifier which you would install to the rabbit ears before the tv. If you still can't get it to work you'll have no choice but to purchase an outside antennae as a result of your being in a weak signal area as signal quality changes by such things as the switch over to digital upcoming and environmental changes.
hi, what you need to do is find the source button or av button on your remote control as it sounds like its changed source this causing your problem. As you probably know your telly has many inputs for dvd vcr cable or sky but these plug into one of the inputs in the back of telly. Usually the problem is just that your on the wrong input channel like av1 instead of av2 or rgb their are many inputs so you might need to press this button 2 or 3 times till you get the right channel, i dont mean 1 to 9 channels i mean input channel like rf input or av input. This depends on what your getting the signal from if its cable and its plugged in via scart lead then it will be an av input but you might have av1 av2 av3 av4 this depends on your telly. If your still having problems then give me a shout back ok best to check all the leads are in the telly correct as this will cause the problem your having ok. Let me know how you get on ok or if you need further help
hi the problem wouldnt be the screen instead your probably right with the video card if the screen was dead it would stay black but with it changing slightly you know the screen is gettin power. When you press the controll does an led flash on the telly to tell you the controll is working just incase the telly is stuck on an av channel. If you have got a dvd player hooked upto the telly switch this on with the telly on and see if the telly will work using the dvd player this would rule out the fault being with the ports on the telly not picking up the signal. If this still dont change anything then it could either be a resistor gone or a couple or it could be what you thought with the video card/controller but their is no way of knowing without testing the resistance at certain points on the board but it deffinately wouldnt be a problem with the screen so it shouldnt cost to much to repair. It mgith be a case that the telly has overheated and blown a resistor thse can be brought for pennys but locating will be the problem let me know what you want to do and wether you are considering doing the repair yourself if you are you will need schematics to follow off and also multimeter to test resistance at certain points on the board.
