PICTURE WONT FIT ALL CHANNELS

No,canceling ur HD channels,will not effect ur regular tv channels.The cable box change or not talk to ur cable company for that info.

Are you using a Cable Card? Have you tried the Channel search function in the user menu. Select Channel set up and do a channel search.

It seems so simple, but in desperation I rebooted the cable box. Picture is now as it should be.

You need to change the Display menu for picture mode to 16:9

no wide fit or scan fit.

Unfortunately there is no listing. I suggest taking a little time to sit next to the television with an notepad to go through each channel one at a time to label what stations come in on what channel numbers. Sorry.

if you have a cable box then it is probably the resolution settings in the cable box, what type of cable box do you have

I just got the same exact one, when it searches automatically the first time it doesn't look for digital channels. go to Menu>manual channel search>cable. it will look for all possible signals and will take forever probably. the free digital channels will take several seconds to switch channel to channel, but they're there! They will show up on your screen as "DC 91-2" or similar. you can switch back to regular cable channels with the input button, you just cycle through all the inputs. hope that helps.

Are you using the original remote control...Reg TV doesn't fit your screen because it's not filmed in HD...But it should be clear but you have to watch it smaller... Usually big screen tv's will have a black trim around the picture...And zoom cuts off some of the picture..Some tv's have wide, cinema and other options...Your TV might just have zoom

Sir, Pull up the on screen menu and make sure the unit is set to display 1080i or 720p instead of 480i. This may be the issue. Good Luck

check your remote that should have all the features to navigate in to the tv menu.if it is not working check the remote it could be faulty or the eprom in your tv neeeds to reset or replace an eprom does a lot of function in a tv set.good luck.greetings from belize.
