Can you change channels on the TV itself when this happens? If so, change the batteries in the remote.

Screen freezes BBC Channels only. Unfreeze by switching off TV. Handset and TVs buttons fail to work. Minutes laterscreen freezes again. No problem with non BBC channels


turning tv off and on wont make it better

you on roof antenna or a cable tv
if antenna only
you may be in weak signal area
or a new construction site or buildings deflecting the signal
antenna problem or needs upgrade

go back to TV set up and re-tune tv to bbc if possible

if it freezes then you know its an interrupted signal

Channel scan only finds 1 channel with basic cable setup on LG 42LD520


if you have a cable box just plug the cable box into a scart socket on the tv, switch the tv to the scart input and use the cable remote to change channel?Scanning for channels wont find anything because you are receiving the channels on a cable box. If you are refering to standard or digital tv signals and your not receiving any channels then either you are only scanning analogue tv and therefore wont pick up any digital tv channels, or your ariel is inadequate to receive an acceptable digital reception and will need to be upgraded. please state country you are in and what you are expecting to receive

TV freezes when switching to a digital channel


The problem your describing can be contributed to your cable box. Depending on your cable company there are times when the box has trouble translating the signal to the tv. You tv is operating normally. Suggest to the cable company to switch your box.

Tv channels wont store on lcd tv,you have to programme them back in after its been switched off


apparently the  the TV resets the channels bewtween 2:00 AM and 5:30 AM, so by changing the clock everyday to ensure that it never reaches this time should resolve teh problem, or just try an not set the clock at all if that is possible, my parents are having the same problem and ive heard changing the clock works, still frustrating, currys have been warning people off buying them due to " tuning malfunction" feel free to take it back to the store and get a refund

Well there is still a problem with the TV. I found that by unplugging the power cable that the digital channels worked. But, when I turned the TV on today the problem had returned, I had to take out the power cable again!

Tv wont stop changing channels


ok, Sony had this issue on their early production. The problem you are having is called a leaky switch. The volume down switch on the TV is leaky. To fix this you must replace the switch. This part is called the switch block. Part number 1-473-549-21

Average cost $26
