The vertical scanning unit inside the tv has lost the sync with the signal coming from the box. Most likely this has been caused by the aging of the components and all you will have to do is to compensate for that by changing (or adjusting, if possible) a resistor in the vertical oscillator.  It's a 10 minutes job if you know what to do. If you don't you can make the things very bad. Take the tv to a repair shop, they might fix it on the spot for a small fee.

My JVC model AV-20F476 has a black-out box that covers most of the bottom half of the screen.


Go into menu and under CLOSED CAPTIONS look to see if TEXT is engaged---if it is set to text 1 turn it off or to text 2,3,4, etc

Text was a feature never really used but it is there, some cable boxes also have this setting/feature.

Let me know if you have questions.

I HAVE A MAGNAVOX TV MODEL 255102-OODD, A MOTOROLLA (VERIZON) SET TOP BOX MODEL QIP2400/1006 AND A JVC DVD MODEL DR-MV150BJ. I HAVE TRIED ALL THE HOOK-UPS SUGGESTED BY JVC AND STILL CONNOT GET A PICTURE. ...


ok, The issue will be in the sequence you have things connected. The connections sequence is going to be controlled by what connections are available. I assume the Set Top controller is connection to your Antennea connection on the TV. Your TV should be on channel 3 or 4. The next step depends on what type of connectors you are using for the JVC DVD. I have an Antennea output on mine so I connected them in series. If you don't have an Antennea output from teh DVD player you will need to connect the DVD using Audio/Video cables which means you will need to connect to the TV alternate Source connector and to watch DVD's you will need to change to that source. Much like you would switch between regular TV and VCR tape on a VCR player connected to the Antennea connector.

What video out put you connected between JVC player and TV ?
Look at back of your JVC player for Video out (yellow color) pin, hook RCA cable there and plug it to Input-1 or 2 in TV.
Now select AV 1 or 2 (what ever you hooked) in TV by remote and hopefully picture will in TV.
need further help, let me know model number of your TV.

Hello,
I just wanted to suggest some things for you to try, if you have not done them already. Try hooking up a known good signal, such as the main input cable from your cable or dish, hook it straight to your tv, and see if you can change channels, and get a picture on low band...2 thru 6, and then if not, how about any picture above channel 6, if you get picture on 2 thru 13 now, it could be whatever you have hooked in between the input cable and the tv...be sure you have the tv on the right channel for your receiver, usually 3 or 4, or if you are using another type of video input cable, make sure you have tv on the right input for that cable and that cable is good...check the in and out of your component unit, for correct cable hookup as well as your cables, in reference to using RCA video and audio left and right in and out...a lot of sets and vcr's will go to a blue screen if they lose signal to them....I hope this helps you out some.If you cannot get a picture from hooking your signal straight to your tv, it could be the tuner got a spike from a thunderstorm, or has lost the B Plus source for the tuner circuit. Be sure that it is not selected for an input signal,other than the cable or antenna mode, the onscreen text should verify this, if you can change channels with or without getting video...a picture....Good luck with it. T.

JVC AV-32F704 32" TV Picture is blurry - cannot read any writing on the screen


You didn't mention if you saw fine white diagonal lines running through the screen from top to bottom. If so, you likely have a shorted Picture Tube which is not usually fixable. If there are no lines seen running through the screen, then it is possible the High voltage transformer which also has a screen voltage and focus control built in that could be bad. I would expect the cost of that part to be about $100, so the repair cost total could approach that of a new set I would guess.
