Question about Samsung Televison & Video

1 Answer

Samsung TV Have a Samsung LN32A450 TV that the other night switched from component 1 to channel 3. Channel 3 has snow and the message "weak or no signal" in the middle of screen. Tried resetting cable box which didn't work. Called cable provider and was told it was the TV not cable. Have 2 other TVs in house that are unaffected. Tried unplugging TV for 5 mins which corrects problem but for only 30 mins or so. Last night volume on remote stopped working,all other buttons on remote work,and volume on TV itself also doesn't work. Put new batteries in remote already.

How do I find a video to hook up my Samsung TV? Model BN68-04027A-03 The TV was a Xmas gift and did find a video and now I can't find it Tx. Wanda


The English owner's manual for the part number listed is available at...

http://www.manualslib.com/manual/146620/Samsung-Bn68-01171b-03.html#manual

Page six (6) indicates the back panel of your Plasma TV has two HDMI inputs, one component (RGB) and a specialized AV input/output connector. The latter requires a cable that is popular in Europe. Adapters to use it with US standard S-Video and RCA composite video are difficult to locate.

HDMI and component cables are available at big box stores (Best Buy, WalMart etch) but are much cheaper from generic internet sellers.

I am not sure about the second half of your question concerning "get to channel 3 to get to all other channels).

I must assume you have told the TV to "scan" for other channels (cable or over the air (OTA) with the black antenna/RF cable connected directly to the back of the TV.

If you have done so I am guessing you have connected the antenna cable first to a RECORDER or CABLE BOX. In many cases, these will only output channel 3 or 4 and block all other channels when turned on. In order to see other channels, you will need to buy a 2-way RF splitter so that both the recorder or Cable box can be connected at the antenna cable at the same time. Please note, doing so will mean you cannot see the output of the recorder or cable box on channel 3 or 4 but must use its the video/audio (HDMI, component, composite, S-Video) outputs from it to the TV. Again, this splitter is available from big box stores or the internet.

You shouldn't have to have the tv to channel 3 or any other for that matter if you are in component. You need to make sure the tv is on the component input from your display menu that can be accessed from your remote.

Tv turns on and off by itself


I had this happen to me just last night. I noticed that it happened as soon as I turned to a particular digital channel. It would turn on and off quicker than I could change channels. To correct this:
1. Remove the cable input, the coaxial cable, from the TV

2. Turn the TV on

3. Change to a different channel

4. Delete the channel that was giving you problems from the lineup

5. Reconnect coaxial cable and you are ready to enjoy TV again.

dont know if this will work for you but it did for us ! good-day !

Ive lost the av channel on my samsung tv; it's


Hello Gem0281; I also have the same problem. Recently my Samsung TV has been acting up, coming on in the night and now the AV channel has vanished!

I have asked spoken to a very technical guy at work called George who has recommended that I connect something, such as DVD, etc. to the back to my TV to see if this helps.

Hope this helps

Just got the TV and trying to set it up using DISH network. Getting a "weak or no signal" message.


Hello! I hope that you have been able to get that picture on your tv. Here are some simple steps for you.

If you are at TV1, where the receiver box is located, the tv needs to be on channel 3 or 4. Depending on the cable that is running between the receiver and the tv, the tv may need to be on an input, such as video 1 or 2. If you are at the TV2 location, where there is no receiver, then the tv needs to be on channel 60 or 73.

If you are using an HDMI cable, your tv usually needs to be on am HDMI input. If you are using component cables, usually the tv needs to be on a component input. RCA cables need to be on a Video input. If you are using coax cable, no cable is needed.

I hope this helps.

Weak or no signal message


  1. Since my problem (Samsung/Comcast) began with a channel selection button pushed on the TV remote when it should have been pushed on the cable remote, I figured the problem lay with the TV.  Although I was getting the "weak or no signal" msg., the actual signal strength bar graphic showed it to be strong. Disconnecting did no good. I surmised that the TV was simply not recognizing the box.
  2. I looked at the manual for my Samsung 750 model. 
  3. Page 20 discussed "Selecting the source". I accessed the TV menu and selected "Input", then chose the "HD..." item from the highlighted list. Voila! My tv works again.
