Samsung 40" LCD TV LNT4042HX

My TV displays the info message box at all times. The message reads:"Not available."
When trying to use info function, info box flickers on and then reverts to the "not available" message.
When trying to access display and audio controls the display continuously scans through the menu. It does not respond to inputs or allow access to any controls.
Thank you.

    I have the same problem LNT4061F. Message pops up Not Available. If goes off after about 5 - 10 minutes and then itt is OK for the rest of the time the TV is on. Changed 4 boards and still have the problem. Good thing I have a 5 year warranty on this TV. I'll let you know if they ever fix it or replace the TV.

    My Samsung LCD TV is a 40" LN-T4042H. The "Not Available" message came up 24 hours ago and is still there. I have unplugged the power, the HDMI, the remote, but it reamins on the screen.

    Same problem just started happening on my tv (different model) that is 1.5 years old. The box comes and goes with no apparent reason. Same with the scrolling menu issue. Has anyone figured out what the issue is and how to fix it?

    I have the same problem with a Samsung 40" LCD TV LN-T4061F. The "Not Available" message comes on when the TV is initially turned on and it stays on for anywhere from 30 min to 1.5 hours before finally disappearing. While the message is on the screen, attempts to use the "Menu" button are unsuccessful because the menu scrolls constantly. Also, the volume sometimes changes settings on its own.

    lns4696dx Not available message starting coming up yesterday - unplugged power cord over night, tv worked fine for 1 hour, now message is on screen again. No buttons on remote work, also power on/off button doesn't work - only unplugging cord works - I have two of these Samsung tvs next to each other (purchased the same day about a year ago) and only this one has a problem.

Digital inputs on Aquos TV's are "always on," usually the HDMI inputs and DVI inputs. As opposed to analog inputs 1, 2, or 3, are only activated once something is plugged in.
Try plugging in another HDMI sources into input4 or 5, if its still not working, the TV needs a new Main Board. Try calling Sharp 1-800-237-4277 and locating a local service center in your area.

SOURCE: samsung 40 inch lcd mode not supported

My 360 and samsung hdtv worked fine for about a year and now im getting the problems mentioned above, not sure if its a console/cable/telly problem but i did the following (temporary?) fix

Unplug your 360 and plug it into another television set, it seems to reset/calibrate itself somehow and then when you plug it back into your samsung tv it will work - mine did but for how long i dont know.

HDMI input says "mode not compatible"


If your Playstation is putting out the signal in 1080p then try changing it to 1080i and see if that works. Not all TVs are compatible with 1080p.

3 year old Samsung 40 inch LCD TV will not turn on


The problem is 4 capacitors on the power supply board. Just had mine done under warranty. They (Sears) replaced the whole power board but you can get larger capacitors and just replace those for alot cheaper if not under warranty.

Samsung 40" Full HD LCD


Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

hope this may help;
