Coaxial connection on older televisions

I have a number of older televisions that still have great pictures, but the coaxial connection to my cable/satellite has gone bad and unless the television has been warmed up for an hour or so, it constantly goes in and out. How can I fix this problem?

Re: coaxial connection on older televisions

These set are world famous for poor solder conection in there tuners, And since these tuners are part of the main board you have to remove the shiel and resolder them. A simple rule of thumb, resolder everthing in this shielded area

My tv cannot connect with my dvd player

If there are no A/V jacks on the set you can get a RF modulator. They are cheap on Ebay and work great. You can also buy them at Wal-Mart etc. All you would do is plug in your A/V plugs into the RF modulator and then plug in a coaxial cable on the output of the box then plug the other end to the input coaxial cable jack on the TV. Make sure your TV is on the channel your RF modulator specifies.

Recently acquired a Fisher PC203 television. Connected to cable and chose CATV. Great picture but cannot get tv past channel 40. Do not see a menu button to add or delete channels. Did not come with...

If I remember correctly, this is an older model set (late 1980, early 1990 I think). Many cable systems of that era didn't offer the large number of channels they do now, and the cable tuning of many sets was very limited. Most cable companies required you to use a converter box to get all the channels. So you probably aren't missing anything, the set just can't do more.

On my Apex TV screen, some of the picture is cut out. How can i adjust the TV resolution?

You cannot adjust the resolution in CRT TVs. Its not like a monitor that is compatible with a number of resolutions from a computer for example. CRT TVs resolution's dont work like that.They take an input usually from a composite, Svideo or coaxial source and display it on the screen.

When you say the picture is cut out is there a black bar on top/bottom/middle of the screen? In older CRT TVs that usually means a problem with the TV itself and would need to be taken in for repairs or replaced.

DAEWOO DTQ-29G1 not working at the Pal system how repair this problem

Make certain you are connecting a set top box to the television with an RCA cable (yellow,red,white). You cannot get PAL through the tuner with a coaxial cable on some televisions. There should be a color system setting in the television's picture menu and you would have to choose PAL (M or N) in order for the television to display it.

Diagonal snow has developed on the screen lately. We have a digital cable box, but calling for a signal boost doesn't help. Is the TV going bad, or the cable box?

You can almost guess that the problem is a bad ground on your coaxial cord. A very very common problem. You may have to many connections...a vcr,DVD player, a video game box etc. all connected to the tv and cable box. Make sure everything is tight and then remove one of the aux video connections to see if you cet a clear picture. The best connections are the ones that twist on...the slide in coaxials are not always the best. You may also need new coaxial cables too! Good Luck!

I have installed a Digitalstream DTX9950 converter box with my TV attached to a rooftop antenna. I can turn the TV off and on with the DTX9950 remote, but I can't bring in any stations, other than the DT...

Are you using the coaxial cable to connect the converter box to the set, or have you hooked it up with rca type video cables? The latter are highly recommended if you want a better connection and have audio/video inputs on the back of your television. But you don't want both A/V & coaxial.
Also be aware that some older antennae will not pick up digital signals well. Try to use a coaxial cable all the way up to the antenna junction. Find out where most signals are broadcast from in your area and aim the antennae appropriately. (Use a compass.) See helpful link here. Your converter remote should have a signal strength button that you can use to check the various channel strengths. If you're using a coaxial link to the tv and have little signal strength, expect a poor picture. You'll also want to select the Mono option for Audio Output in the converter menu.
Finally, depending on the age of your set, if you're using rca video inputs, use the TV/Video button or the AV button on the TV or universal remote to switch the input from the channel on your TV to the video 1 setting (or whatever picks up the digital converter signal) so you'll get that clear signal. Then you can use the converter remote to change channels, adjust volume, etc.

Input button says there is a setting for computer but manual does not give instructions

there are a number of methods that will allow you to make the connection. Many computers have incorporated composite (RCA) or S-Video (TV-Out) output that will either mirror or, better yet, extend your desktop beyond the monitor. For desktop systems, there are numerous AGP video cards available that offer a variety of video outputs. For example, ATI's Radeon X1950 PRO video card includes composite, s-video, and component video connections for analog signals. Of course, it all depends on what inputs your television can accept. If it has multiple input ports, remember that there is a hierarchy in terms of signal quality among the three typical types of connections, which, from lowest to highest, is composite, S-Video, then component video. So opt for the highest quality connection supported by both devices. Many older or more basic televisions may only have a coaxial cable connection. In this case, there are video cards with coax outputs and scan converters that will pass the signal through a coaxial cable directly to your television. Oh, and remember that you'll also need to connect your sound card's LINE-OUT connector to the TV for sound.
The tricky part may be finding the right cables to go from the computer to the TV, since there are several types of RCA (1 or multi-port) and S-Video (4-pin and 7-pin) connectors. One product I found, the Pro S-Video to 3 RCA cable allows you to connect your desktop or laptop computer's S-Video to your TV. These adapters are compatible with both S-video 4-pin and 7-pin receptacles and also connect your PC's stereo audio output to the TV.
But don't run out and buy any special video cards or cables yet... There are certain limitations of using older CRT televisions as computer displays that can easily render the advantages of size and affordability almost completely negligible. Perhaps the greatest constraint is the relatively low resolution of standard, tube-based televisions. Because of their design to accept NTSC (North American), PAL (European), or SECAM signals, good old-fashioned analog television sets generally cannot display resolutions greater than 640x480. That was barely adequate for a 14-inch monitor ten years ago, so just imagine how it might look on a 32-inch TV screen. Have you ever tried to read those fuzzy disclaimers at the end of a TV commercial? Viewing your computer's video signal through a CRT television will not yield the detail and clarity that you would normally expect, although for games and video playback it can produce acceptable results.
