This may be a tuner failure, or a fault in the AGC or IF circuits. This may not be cheap to service unless it is a simple cold solder connection on one of the circuit boards in the mentioned areas.

Input signal.


You should be able to connect the TV to the antenna without the tuner converter box. If you still do not get signal you may need some type of signal amplifier between the antenna and TV. Hope that helps.

Trying to hook up digital converter box but cant get reception


This seems related to the TUNER and the IF section as the sound- audio and picture- Y signal does not process with the correct alignment.

Some of their very old sets the video input was located on channels in the 90's; Try scrolling down from 99 to 90 to see if you locate the video input; this is just the way they did things in the older sets.

Cant find a signal to get channels on portable tv


Is this TV digital ready? if not you will need a converter box for the new digital signal that the government reguired this past summer. It should work if hooked to a cable box or sat reciever but without the converter box you can no longer recieve signals through the air.

Plugged in, cable connected, turned on, says "No Signal"


OTA signal? Check your antenna orientation and if there are any tall objects that would interfere with the signal. (See antennaweb.org or tvfool.com for signal directions and distance to the station. antennaweb assumes an external antenna and is very conservative with station information.) Scan for channels with Menu > > (right arrow twice) up or down to AutoScan and hit enter. Use add channels to include stations with the antenna in a new direction.

If you are using the built-in antenna, you may not get digital signals. Try an external antenna (see above sites). Digital signals are enough or zero.

This TV doesn't have a cable tuner so a set top box would be needed for cable stations, check the box directions for the station you need to tune the TV to access the signal.

I hope this helps.

How to connect settop box to tv with no avs


You will have 2 UHF plugs on your set top box.. One for input (aerial) and 1 for output (TV). Connect your main aerial to set top box UHF input and connect an Output UHF lead from set top box to TV. Next switch on set top box and retune tv on a spare channel until you get set top box channels (good idea to switch on menu on set top box so you know you are tuned into set top signal )

My analogue tv doesn't do anything when connected to the new set top box. The scart is connected and the aerial also. Are there some anologue tv's that can't receive the digital signal? I already have 1...


Have you checked that your aerial is connected into the set top box & not into the TV? The aerial signal has to go into the set top box & then the box will be connected via your Scart cable into the TV. On the TV you will need to select the Scart input ie. AV1. This should give you the set top box incoming signal, you might then have to tune in the box by following the on screen instructions. Hope this help.

Hand held casio tv vs digital signal


I have my handheld Casio TV-980 up and running with a converter box. All I needed (in addition to the converter box and standard rabbit ears [UHF/VHF] antenna) was an adapter with an F jack on one end and a 1/8" plug on the other (Radio Shack catalog # 278-257, about $5). The 1/8" plug on the adapter goes in the external antenna jack on the TV, and the other end connects to the coaxial cable that goes to the TV (RF out) jack on the converter box. The adapter would have been a little cheaper at my local, independent electronics store, but they were sold out.
 
If your antenna has flat 300 ohm wire connections, you'll need a balun (Radio Shack catalog # 15-1297, about $8) to connect it to the coaxial cable that goes to the Antenna (RF in) jack on the converter box.
 
I’ve tried 2 different converter boxes with the handheld TV, and they both work well: Insignia (Best Buy’s house brand, same as Zenith) and RCA (from Target, same as Venturer), so any government coupon-eligible converter box should work.
 
A few other tips:
 
1. I always turn on the converter box before I turn on the TV. The cpnverter box seems to take control better that way.
 
2. When I turn on the TV, the tuner doesn’t automatically go to channel 3 or 4 (where it should be set when using a converter box), and the picture quality is poor. If I use the tuner on the TV to get to channel 3 or 4, the picture quality is vastly improved. I have to do that every time I turn on the TV.
 
3. Placement of the antenna is very important. I like to watch my handheld TV when I'm on the computer, and the reception is better the further away from the computer the antenna is located. I'm actually using a 6' coaxial cable for the antenna, but I could also have used 2 shorter cables with a coupler that has an F jack at both ends (Radio Shack catalog # 278-304, about $3).
 
If your battery-operated TV does not have an external antenna jack, instructions for connecting it to a converter box can be found at

There are a few battery-operated converter boxes available, but for do-it-yourselfers, this web page also contains instructions for building a 12-volt converter box power supply.
