My samsung tv channels keep scrolling from 135


Hi Jorge

Check on the remote if the buttons aren't stuck / sticking then check on the side panel of the television if the button there are not pressing against anything.

Lastly check to see your channel setup is fine and do a auto scan for the channels to ensure that it's not a memory issue

JVC TV LT-42X579 LCD TV 42 in.Does this TV have a Lithium battery for maintaining memory, similar to PC computers?


No. It has no such battery inside. Its memory IC is non-volatile type, and need no back-up electric charge to retain the data, even after it is switched OFF. http://electronicshelponline.blogspot.com/

I recently got a basic cable plan but am only getting a couple of channels.. How can I change this?


The best thing to do is contact the cable provider and ask them to provide a list of the channels you are suppose to get. With all the channel mapping and digital TV display devices these days, you might need to have your display device scan for channels if the signal is not tuned through the cable box itself. The channels may be there but the tuner in the TV device has not scanned the channels to register them into it's memory. Also make sure to set the TV for a Cable mode of tuner.

Sharp 32 inch lcd tv won't reconginze channels when connected to antenna. Why? The screen now looks like a defragmenting on a computer screen.


You probably need to do a channel scan to find TV channels and progrma them to the TV memory. Using your remote control select Menu mutton and follow instructions for "auto channel scan"

Turn tv on and get no program or weak signal message.


You should be watching tv in no time. Email me and let me know how it went I would like to know if I was able to help. surfpro@yopmail.com

1-You didn't say what model tv you have. Is it a HDTV?
2-Are you using an over the air (roof) or set top antenna connected to the tv?
3-Are you getting the no program or weak signal message on all channels?
4-Have you tried first cycling through the source or input button to make sure you are on TV and not on an input. Sometimes if you are on an input and for example the device connected to that input is off you wil get a no signal until you turn the device first but you probably already know that.
5-When you were in the process of scanning for channels assuming you had an over the air antenna connected did you make sure and select the ota option and not cable? if you have an ota antenna and not cable you need to select ota before scanning for channels.

Now assuming you have an ota antenna and you chose ota before scanning or doing a re scan and after the scan you still get the no program or weak signal message that means there is no signal and you may be using the wrong antenna or try moving the antenna in the direction of the television tower if you know where that is or turn in another direction but unless you are using the wrong antena you should get something.

Assuming you received some channels or even if you did not, try to and add channels by hand. Heres how: first you need to know the RF frequency channel or digital channel its transmitting on you just cant input the number of the display channel you want like on a tube at least not initially but you can after you first input the rf or digital channel number first and saving it on your tv then you can just input the display channel number you are used to. Heres how to manually force the tv to enter a channel without a scan or re scan and possibly loosing other channels with a rescan.

Go here http://www.rabbitears.info/search.php and go to state search choose your state from drop down list and click search now do you see the list of stations? on the left you have the display channel (thats the number you usually entered on a regular tv) and next to that is the digital channel (thats the number you need to enter on an hdtv or dtv initially to force the tv to accept the channel because if you just enter the number your used to initially the tv wont find it) the tv should now automatically redirect you to the channel you are normally used to and any digital equivalent and any sub channels for that channel. Now save it into memory in your tv menu channel list. do this for every channel for your area if you were unable to pick up any stations during a scan.

ok i am typeing this right out of the book/
operating your tv: Once you have connected your tv to an anntenna or cable system,plugged the tv in, and put batteries in the remote, you are ready to use the tv. the first thing you should do is program your tv so it memorizes all of available analog& didgital channels.PROGRAMING YOUR TVS CHANNEL MEMORY: your tvs memory determines the channels thet are available using the "up ch down" buttons. if a channel is not in memory . you can tune to it with the numbeer buttons, but not with the up and down buttons . follow these steps to program your tvs memory:
1) Preset
press the MENU button twice to enter preset menu

To memorize all available analog and didgital channels
press the ch down button to highlight FULL SCAN then press VOL.+ to begin channel scaning, the channel scanning starting with analog channels then to didgital channels. after your tv finishes memorizing the channels, it will return to normal tv viewing. I hope that this fixes your problem thats just the main section on the programing part so if you need further info just ask!
