Question about Samsung Televison & Video
I have a new computer and am using my 47in Samsung LCD flat screen as the monitor. It is hooked up through a Bose V25 home theater set up via HDMI cables. The problem I am encountering is with the aspect ratio. The display cuts off all the edges. I manually turned changed the aspect ratio to 'Just Scan' and it fixed the issue, temporarily.In a seemingly random fashion, the aspect ratio will revert back to what it was originally with all the edges cut off. If I change sources, it will generally revert. Is there a way for me to lock it in for that particular source?
When you set it to just scan the source will determine the scan. I would remove the bose from the unit and connect the cable or sat box directly to the hdmi in of the tv. if the problem persists check Samsung web site for software upgrade. If upgrade does not fix replace the main circuit board.

I have LNS4692D. Returned from vacation, turned tv on - no picture. Tried turning tv off for 4 hours- nothing. Symptoms are: tv is on - no picture , just sound; menu doesn't show, volume bar doesn't show;E.Saving is working - the backlight is changing from lighter to darker.
Found this website and ordered T-con, otherwise known as the LCD panel driver board, p/n# Bn8101286a ( thanks premtech) from partstore.com for $124. Part number BN81-01286A A/S T-CON Board.
1.Remove plastic cover. There is an arrow for each screw that needs to be removed. Make sure to unscrew pins next to VGA port. I've spent some time trying to figure out what else is holding the plastic panel until I found this pins.
2. Remove big metal shield in the middle of tv that is covering main components. This shield is being held by small black screws all around it.
At this point you will see cover of T-CON. Here is the picture
http://www.avsforum.com/avs-vb/attachment.php?attachmentid=118863&d=1220531321 (thanks ldac9). Do not attempt to remove that cover yet. Proceed with a next step
3.Remove metal panel that holds main components. Locate big chrome screws that have arrows pointing to them and unscrew them. Remove 2 more screws on the bottom of the panel that holds it together with a box for cables. At this point the main panel will be lose
4. Carefully start lifting the panel. You will see that there are connectors going from components on the panel to components on the lower panel and T-CON. Carefully unplug these components and raise the main panel.
5. Remove 4 screws that holds T-CON cover. Pull the cover so that T-CON is completely exposed. The cover is connected by thin alluminum , don't hesitate to pull it , but don't rip it out.
6. Once T-CON is exposed you will see 2 red ribbons. I've spent some time to figure out how unplug those from old T-CON board. Here is the suggestion. Don't try to pull it out. All you need to do is to lift small plastic lever that is part of a connector. Then ribbon can be slided out. If not sure what to do, see how this is done on the new T-CON. It has a principle of buckle on airplain safety belts.
7. Remove old T-CON and install new you.
8. Follow reverse order.
I've never fixed TV before , but this was totally successful project.

Yes, it is possible the settings from your cable box maybe set to the wrong ratio eg:letterbox. Depending on what type of box you have, look in the cable box menu for a settings option, then change the aspect ratio to a different format.

SOURCE: I have the samsung LN52A550. When I turn the tv on a blue screen appears. I tried changing the source with the menu button but does not display anything. The TV is about 2 years old. The sound works.
Method one- with set on, hold down the exit button on the remote for 10 seconds. It will bring up the warning it will reset to the defaults it had when removed from the box and powered up initially. in the warning box it will show the cancel button highlighted initially. press the left arrow to select the reset option. You may end up doing this blind, so you may need to try it a couple times and the only indication of where you are is just a slight flash from part of the screen.
Once that left arrow has been pressed once, the reset option choice changes to "Ok" or "reset", press "enter" The set should
do it's thing to reset and then shutdown.,
it should get you into the hotel settings, but you can reset to factory defaults from there, changing any other settings may limit access to the normal settings.
Shut the set off.
The while holding the mute, menu and info buttons, trun the set on while holding them down. If the functions portion of the board is working, it should bring up hotel options menu.
