JVC AV-32F577 No Vertical

I have a TV that has no vertical, has sound and has good hortizontal (rgb) line in the center, I was thinking a cap might be out in the circuit. Any ideas on which caps might be out.
Thanks,
Joey

AV-20920 thin horizontal line


hi, usually the cause in jvc tv is, a bad contacts on the vertical chip leges. you should solder those contacts. another option is to change the vertical chip . more rare is a missing of the 27v voltage that goes to the chip. in that case you should check the port of the high voltage transformer.
good luck!

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!

YES THERE ARE 3 CAPS. 2 ARE SMALL ONE LARGE IN THE VERTICAL CIRCUIT. 1 OR 2.2 uF AND A 1000uF. ALL ARE VERY CLOSE TO THE VERT. IC AND YOKE PLUG. PHYSICAL EXAMINATION SHOULD SHOW WHICH ONES DRIED OUT AS THE HEAT SHRINK WRAPPING AROUND THEM PEALS UP. ALSO WHEN YOU UNSOLDER IT YOU MIGHT SMELL "STINKY FISH" AS THE ORGANIC ACID INSIDE IS LEAKING OUT THE BOTTOM. LOOK FOR BROWN OOZE ON THE LEGS ALSO.

It may be a dry solder point somewhere near the vertical IC. First take look at the solder points and if you found cracks pls resolder it. if the lines continous you have to replace Caps near the vertical or circuit.thank you

No video on my JVC AV-30W475 30" flat screen.


It sounds like you have bad solder connections in the Vertical circuit or the horizontal circuit. The Vertical IC may need to be replaced if resoldering does not help.
You will need to call a good TV Tech for this repair.

One thing you should not do with electronic devices which have a start up proceedure is to turn the power off, and then on again without a wait of about five minutes. Some equipment manuals warn you about this, and specify a longer period. The start-up has to have time to reset. It will be more likely to reset if you do not leave it on standby, and even unplug it. In your TVs case you need to describe the distorted picture as it may give a clue to a fault, or incorrect start-up. The horizontal line indicates the frame timebase had stopped working. No picture could be a fuse blown inside the set, or a timed cutout which may reset after a time. Try after several hours to see if it comes on. If it is just the frame timebase (vertical) it is worth repairing.
