JVC Television Model AV 27820

A horizontal line. Vertical problem. Started with retrace lines at the botton of the sreen, then it broke down to a horizontal line, you can turn it on for a few minutes and it brake down again.

Thanks, George

    I Have a JVC AV-27920. I have horizontal retrace lines at the top 2 inches of the viewing screen. It started at 1 inch and they would disappear as the set warmed up. Now they are there continuously. I suspect there are weak or bad capacitors in the related circuitry. Is there a way to determine what area of the circuitry to replace parts? Or at this point would it be smart to shotgun all the electrolytics? I have replaced a few of the caps (mostly the larger uf and higher voltage ones) and touched up some questionable solder joints. No help.
    Thank you,

If it will not adjust up or down or left and right the convergence chips need to be replaced.

See attached photos of board that is in your set:


This can be a do it yourself repair and the parts do not cost a fortune.

Can I help?

JVC AV-27820 turn on the a white line accross middle

Total failure of vertical sweep occured whic your JVC TV. There are mainly two resons for this fault.Loose soldering terminals of the vertical output IC is the first one. The second one is of failure of the vertical output IC itself. You have to locate this vertical IC. It can be located at the main board. Vertical IC will be screwed on to a metal heatsink to radiate heat from it while it works. You can identify it very easly, if you have knoledge in electronic circuts abd printed circuit boards.
Resolder all the solder terminals of this IC first, by applying a little more solder; without making any solder bridge short in between the close adjecent solder terminals, and see whether it helps you. If not replace it with same type and number. OK.

I have a JVC AV-32F703 tv just replaced the vertical IC tv comes on but immedeatly goes into shut down mode by what could the problem be? Retrace lines was on top of picture before it started going into...

Chances are you should have checked some components related to that IC,namely an electrolytic capacitor.They tend to leak or short.That IC burned for a reason.

Video just reduced to a tiny horizontal line across the screen. sound is fine, what could be the problem? jvc tv model av-32720

You have a bad vertical IC at its worse or one that may need resoldered. Be sure to check the grounds on this IC and check for rings around the pins. And you can bet in the immediate area you have bad capacitors that created a hot vertical IC. This will cause the Vertical IC to break down!

Horizontal white lines across top problems of my television.

This is probably bad/leaky capacitors in the vertical circuit, around the vertical IC, or the power supply that feeds the vertical. Sometimes you can see domed/ bulged caps or what looks like liquid on the circuit board around the leaky ones. The legs on some caps can even corrode to the point the leg is missing. Care must be taken when replacing them because the acid from the caps can eat away foil traces on the circuit board. All acid must be cleaned off board to prevent further corrosion of parts

Vertical jitters on picture - JVC AV48P776

What you are experiancing is loss of High voltage. The line is called a retrace line. It is usally caused by failure of the flyback circuit or aging of the TV tube. This is the single most common failure with CRT based display systems. The high voltage can be tweaked up, to accomidate for the age of the tube. Its a short term solution. Because of the high voltage nature of this circuit, suggest a professional repair.

Jvc AV-36f802 not power up, automaticly shut down within 2 seconds

Hi, You may also want to check the Vertical IC. In some units I've worked on, failure or cold solder in the vertical IC triggers protection. Good luck and cheers.

Faint horizontal lines in picture

This is usually caused by a problem in the Horizontal Output section, around the Horizontal Output transformer usually a capacitor or diode going or gone faulty... the line you see are the Horizontal "Retrace" lines that are useually "Hidden" when the circuit is OK..
