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

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

Our lg42lt75 tv keeps freezing on dtv the only way we can it going again is to turn the power off .is there any way we can stop this?


Your current software version of the TV may be out of date, contact your LG dealer as this might have to be updated, older software can give this effect. If your incoming signal from an aerial source is weak then this can also cause problems the strength of signal can also be checked at the same time.

Panasonic plasma won't change channel or volume


Also had the same problem with our Panasonic 50" Plasma...could not change the channel or the volume (with the remote control nor with the actual TV controls). Before I called for repair, I UNPLUGGED the TV and then plugged it back after a minute. I was surprised....the TV started working again. (Switching the TV on and off is not sufficient). I could change channels and volume, etc. So this saved me a repair this time. Might be worth trying this solution. Wouldn't hurt one bit, but rather save you a repair fee.

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

Samsung LE40R73BD DTV freezing, wont chnage channel


i've just some digging around and found that you can access a service menu and perform a reset which sorted the issue for me.

Access the service menu by pressing, in order, whilst the tv is in stand-by mode:

info
menu
mute
power

when the tv comes back on you will have a service menu; select option 12 (reset) the tv will then switch off.

this will reset your TV back to factory defaults.

turn tv back on and you should be prompted to go through the plug and play setup again - go through everything and then all should start working OK (it did for me)

You need to press the button on the top right of the control ( the TV button) once and that will allow you to control the tv once again. Problem occurs when you accidently push VCR or DVD button which means remote control will try a different frequency to operate a VCR or DVD that isn't there. Hope this helps.
