    We've had this tv about 18 months. We've been happy with it. Recently, though, when we turn in on in the mornings, it goes through a series of turning on and off several times before it finally stays on, about ten sequences. We haven't had the problem of it turning on/off during the day, only the first thing in the morning. Any suggestions before it gets worse?

    My Samsung has the same On/Off loop on power up. The first time it did it came on after holding the button in on the set. Now it just clicks no picture no sound.

This may not really be a solution to your problem, but here it goes. If you are not sitting a particular distance from your tv you will experience slight pixelation. I have this tv myself and I think it looks great. Now when I am sitting up close on a station that is broadcasting in 720p(which is pretty much every HD station) It looks only pretty good...I sit back and it is fantastic. The good rule of thumb is take the number or inches your TV is in yours and my case 40, divide by 10 and then multiply by 2...and that is the number of feet you should be for optimal viewing distance. So 8 feet, you would be surprised to see how sitting this magic number away makes a difference.

I lived with it for about six weeks, then took the back off the TV. Just now it seems to be fixed, but I don't know if it will last.

I disconnected the wire leading to the channel up/down, volume up/down and source board, turned on the tv, turned it back off, reconnected the cable, and everything seems fine now.

There is a problem with the power supply in your TV. The regulator switch is causing teh clicking sound you hear. In order to fix it, you will need to replace the power supply. This is done by taking off the back cover of the TV, locating the power supply which is usually a yellow board that will have many high voltage capicators on it and replacing it with a new one.

Forgot my password I cant watch any channels


Hi,

The easiest way is to reset the TV. There are 3 possible resets for this TV. press and hold Action and Power on the TV until self check appears-- then unplug the TV wait for 30 sec. then plug back in. The reset should take care of any channel lock/ game guard settings

Also Volume down on unit and sleep on remote. Same process wait for self check then unplug for 30 sec. plug back in and turn on.

Last Volume down on the unit and RH-Split on the remote-- same process
hope this will be helpfull. Please rates me . Goodluck...................

Captions are locked on and guide cannot be accessed to turn them off. Also, volume is stuck at 0. When you adjust volume it goes immediately back to 0.


You might have the CHILD LOCK feature on.

Use the remote to access the MENU then SET UP then CHILD LOCK.
Set CHILD LOCK to OFF.

If this doesn't work, try holding down the MENU BUTTON on the front of the tv for 10 seconds until you hear a beep. This works for some models.

Or if all else fails, leave the power cord unplugged overnight and this shoud reset the internal memory back to default settings.

I tried to download the user manual at the following link but the site was temporarily down

Gppd luck and let us know how you make out.

I need to re tune my samsung tv but have no remote any ideas?


you can always use the button on your Tv itself.

ie menu = Menu
Channel up/down = take you up and down
volume = goes left and right.

follow these steps

Menu,
channel down button to CHANNEL
press the volume button along
channel down button to AUTO STORE
press the volume button to Start the scan.

right now you have your telly tuned in. What you could do it get an old sky remote off a friend/ neighbour. or buy from argos etc ( a lot cheaper then getting a replacement samsung one)

press the following buttons on the sky remote to program it to work with your samsung tv.

TV,
RED + SELECT
TV.
0060

try the volume if this works press SELECT to save this code if it doesnt press Tv then try the volume again. repeat this step until the volume works your telly. once it doest dont forget to press the SELECT button to save.

Now you will be able to change your volume use the number keys. if you also press the HELP button on the sky remote this will also change your AV / SOURCE I hope this post helps you out. When it does please leave a thumbs up for me Please

I had a similar problem, checked all of the TV's control settings only to find out that my cable box had an independent "mute" function that automatically turned on the closed captions when activated. Once I found that and turned it off, all was fine.

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.

clip_image001.jpg
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;

Same problem with my set. The volume was either fully up, or fully down (usually down), and other controls didn't work- like I couldn't access the menus and could not adjust the width of the screen/aspect ratio.

I lived with it for about six weeks, then took the back off the TV. Just now it seems to be fixed, but I don't know if it will last.

I disconnected the wire leading to the channel up/down, volume up/down and source board, turned on the tv, turned it back off, reconnected the cable, and everything seems fine now.
