Scanning dtv channels

When I select dtv input and try to go to the TV icon on the main menu the screen turns blue and will not let me exit or do anything. I have to turn the TV off and then I can return to the TV input and watch DirecTv. Can get to the TV icon from this input. Have some digital channels that I was able to pick up off antennae but now I cannot scan for them. Any help would be appreciated.

    Periodically when I turn on the TV to the DTV input, or switch to that input from another one, the screen remains blue and the OTA signal never displays. I can change the volume but not the channel and the other inputs work fine. My "solution" so far has been to turn off the tv and wait for a bit then try again. I have left the set unplugged for two hours but that failed to improve the situation. My googling leads me to believe there is a problem with the ADC, but the same googling indicates that I shouldn't mess with the ADC settings in the service menu. Any thoughts? Thanks.

    I have the same problem. NTSC works fine, but when I switch to DTV, I get a blue screen. Usually when you have a weak signal or no signal, it will go to black screen and display no signal. Mine doesn't do that, it stays at the blue screen. This happens most of the time now. When I go to the scan mode on the menu, the menu disappears and does not return. Then the TV is hard to turn off and back on.

Go to menu setup and do the full system reset setup option... Then before you scan for channels make sure it is set to cable... This fixed the problem for me.

Do a reset to this TV. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

How do I bring the menu up on a zenith VCR combo without the remote


Without a remote control you can't. To select a suitable replacement remote control, you should be aware about the set up codes for your device brand. To know more about it, visit the sites linked here. http://electrohelponline.blogspot.com/
http://remotesearch.blogspot.com/ Being there is no menu button at the front panel of your TV, without a remote control you can't select it's inputs. Universal remote controls are available by some online shopping centers too. Visit some of them.
Good luck

LG 26LH2000 television. Last 2 days when I turned my TV on there was only sound, and black screen.


back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

I have a 39 inch element tv i cant program the cable channels


Typically you can access the menu, select "tuner" or something similar, make sure you're selected either on CATV or ANT (or similar), then do a channel scan. Should be pretty straightforward. Oh, and make sure you actually HAVE cable. If it's digital cable, you may need an external converter box for it to work.
