I have been looking up about the switch to Digital Brodcasting. Some of the Digital TV specs stated that networks have a set amount of bandwidth for their Digital TV stations. Since one of the reasons for a national switch to Digital TV is to clear up the airwaves, I would assume that the Digital TV runs through the internet. If this is so then I would like to know if dial up users will be able to watch Digital TV. Also could Digital TV users use the phone line while watching TV?
Can digital TV work with dial up internet?
No, as a practical matter you cannot watch digital TV over dial up Internet connection..
The data rate for dial up is much too slow for that. It would be possible to download a short video over a period of hours and then watch it, but it's not very practical.
People normally get digital TV signals over the air with an antenna (OTA), by digital cable, or satellite TV. It is possible to send digital TV in real time over a very high speed Internet connection, and in some areas you can get the equivalent of digital cable TV that way using fiber optic lines..
The bandwidth allocation for a digital OTA channel is exactly the same as the analog channel that they replace. Unlike analog broadcasts, digital stations can be set up on adjacent channels without interfering with each other. Also each digital channel can send out up to six video feeds at the same time. That's how they can cram more programing into fewer channel allocations.
The old NTSC system used OTA channels 2-69; the new all digital ATSC system uses channels 2-51.

TV lead question.......?
What does an RS232 lead do when connecting my Sky box to my 42" plasma TV? I have just bought the TV and noticed that there is a connection for RS232 on the back of both the Sky box and the TV and assume that thes means I can connect the Sky box to the TV without the use of scart leads, as the TV does not have any scart connecitions. Are these leads easy to get hold of, and are they available to buy in any high street electrical shops?
TV lead question.......?
An RS232 cable is known to most as a VGA cable. At a retail store ask for a VGA cable. They are your typical cable to link a computer to a monitor. they come in all different lengths including custom order lengths. I just install a 57' RS232 cable in a confereence room. Typically for a Sky Box or for any cable or satelite box there is multiple connection choices. RS232, Component Video, HDMI, and DVI. HDMI is the best. then DVI, then RS232. then Component Video
Reply:Best answer ?!
Most factually incorrect answer more like ;-)
An RS232 is NOT a VGA cable. Report It
Reply:The socket on the TV will be for a VGA PC connection but cheaper models might not provide facilities to use it. Does the TV have video and audio RCA (Phono) sockets and remote control options to select AV instead of TV? If so, you can try a SCART to RCA cable (3 RCA plugs) or SCART to RCA plug and an RCA cable. You could obtain these from Maplin.co.uk or via searching for "SCART to RCA cable"
Reply:Yes you can get an RS232 from any good electrical store. Its just another means of communication between two devices and is a little smaller than scart but not as well screened nor can it carry so much data. Surprized there is no scart connection on your new telly??
Reply:There is no need to connect the RS232 socket to your TV.
You most definitely cannot use it as an alternative to HDMI, SCART or composite connections as reported by one responder. i.e. it is not for getting the picture from the Sky box to the TV.
The RS232 port was included by Sky for add on devices and controllers. For example some people connect their Sky box to their computer. The RS232 connection is used to control the Sky box, but again it has nothing to do with the picture.
If your TV has some internal device that can be controlled by a Sky box (maybe a hard drive video recorder) then you can get a cable from PC World.
Reply:I believe the RS232 is known as serial port, for serial data comunication, in TV it usually uses for inputing hex command to the TV, (like remote commander).
Reply:In telecommunications, RS-232 is a standard for serial binary data interconnection between a DTE (Data terminal equipment) and a DCE (Data Circuit-terminating Equipment). It is commonly used in computer serial ports. you can buy them at any computers shop.

On the back of the TV, how many holes does the connector have?
It should have 15..Your PC has 15 so the TV should have the same number as well.
This is what you need: http://www.amazon.com/VGA-Male-Cable-10-...
Might search ebay for cheaper deals :)
Reply:You can do that but you need the right cables or a better graphics card not a on board one.
Reply:You need to go to best buy or staples....a computer store and buy a VGA cable. Hook it from you computer to your TV and you are good.
Reply:You attach a S video cable from Belkin! You can get one at RadioShack or WalMart or any Electronic Store. They're called S-video cables! Just like this one:

Tv experts need help repairng my tv?
What I have done for customers in your case, who didn't want to spend too much was. Pull the tv apart %26amp; remove all the broken pieces away. You can now try the remote to see if it works. If not then:
Solder 2 wires to the power button leads on the printed circuit board (also removing the old power button). Then go to Radio Shack %26amp; buy a momentary contact push button type switch %26amp; drill a small hole through the cabinet %26amp; solder that to the 2 wires. If you're just going to scrap the set anyways %26amp; you want a cheap fix, there's your answer.

Help setting up tv, and dvd vcr combo with new cable box~!?
Hi, I reciently bought an LG HD tv... and i just got my new digital cable box from cable vision. Now.. I have got the tv to show digital tv by hooking up the coaxial from the wall to my cable box to the tv.. also, i noticed that it had one of those composite wires (red, green and white i believe) i have put that into av1. by watching TV through this, i get the digital tv that i wanted...
Now.. my question is.. I have a DVD/VCR combo.. do i hook this up by buying another coaxial cable so that it goes from wall -%26gt; cable box -%26gt; vcr -%26gt; tv? and is that all i need to do? or do i need to also have a composite coming from VCR/DVD to tv? Please show me the most efficient and best combo. Thanks~!
Help setting up tv, and dvd vcr combo with new cable box~!?
when setting up a cable box, vcr, and tv you need to connect the coaxial cable in the following order:
Cable Box -%26gt; VCR -%26gt; TV
1. connect the coaxial cable to the in port of the cable box.
2. run another coaxial cable from the out port of the cable box to the in port of the vcr.
3. run another coaxial cable from the vcr to the tv.
like you mentioned, the dvd composite cables also need to be run to the back of the tv as well.
Reply:It really depends if you plan to do a lot of recording with your VCR. If you never record shows and only want to play back movies, just hook the VCR through the composite wires (red, white, yellow) to av2.
If you record a lot of shows, set it up as Steve suggests but remember, the output of the cable box is channel 3 so you must set your recorder to 3 and use cable vision remote to set the channel to record.
Now.. my question is.. I have a DVD/VCR combo.. do i hook this up by buying another coaxial cable so that it goes from wall -%26gt; cable box -%26gt; vcr -%26gt; tv? and is that all i need to do? or do i need to also have a composite coming from VCR/DVD to tv?

How do i fix my TV?

Reply:Your TV is probably set up through the cable box, you need to turn it on and off from there, the TV set should be set on component 1 or 2 for the cables remote to work. Turn the sound all the way down manually so when it comes on you won't blow a speaker or your ear drums. You just hit the wrong button in a panic, it's an easy fix so don't freak out.
Reply:Take it to a TV repair shop.
Whatever you do, DON'T go opening it up. There are huge capacitors in there that can store a large electrical charge for years, even if the TV has been unplugged. Touch the wrong thing and you can be killed. (This is especially true of TUBE TVs, not sure about LCDs, plasma, etc, but i'd err on the side of caution)
Let a pro fix it. Or, if it's cheap, buy a new one.

Image on TV constantly blacks out, what is wrong with it?
Lately, my TV (not a plasma, just those old heavy ones) has been acting strange.
Whenever you turn it on the images do not come up (the sound is still there though). You have to turn it off and bang the tv to death, and then it would at least work for a few seconds. It constantly blanks out--even if you try hitting it to make it work.
Sometimes I get lucky and after hitting the sides and the back, the TV will work fine, but usually, it rarely works right.
Why does the image dissapear? Is the TV busted? Is there anyway to fix it, or do you have any suggestions? Is there somethin wrong internally, and should I open it to fix/find out what the cause is?
Image on TV constantly blacks out, what is wrong with it?
When a TV set like your's blanks out, it's most likely the Vertical Deflection is failing , and to protect the picture tubes on it from burning a line into the center of the picture tube, IT BLANKS the picture !
Been there done that....
And depending on model and Brand, you could have loose solder on the Vertical output IC, the Vertical power supply circuit or the Yoke Plugs.....
That's what normally causes a picture to blank out on the OLD Heavy ones....
And then there's the 9 Volt regulator that gets bad connections.....That's another blank-generator on certain brands....
Now on smaller TVs like a 32 or 35 inch TV with a Picture tube you can touch with your hand (called Direct View CRT), on those I normally see the HORIZ drive transformer and resistor get loose connections...but those don't CHARGE UP when you turn them on either....
That's why TV Techs ask a lot of questions....Is it a CRT you can touch (Direct View) or a plastic screen on a big box. (CRT projection TV)
Do you see a thin line from left to right before it blanks? Does the top and bottom shrink at all? (Vertical !)
Does the TV develop Hi Voltage? Can you hear it crackle when turned on? (Horizontal)
What brand, What model?
These all help us to determine your failure.....
