Question about JVC Televison & Video

Open Question

My 2000 JVC TV MODEL AC120V60HZ began having lines run across the top part of the screen. It didn't affect the picture but just the other day when I went to turn on the tv which is hooked up with a satallite box to directv, the screen came up blank and then kept automatically shutting itself off. I attempted to turn it on with repeated steps and then I heard this small spark like sound in the back and suddenly a burning wire odor was prevelant. There is also a little circular shape on the front of the screen that says timer. When the tv would normally go on it would light up green, but just before the wire odor and constantly going off by itself it wouls flash red. Any idea what the problem may be and cost? It's a 2000 model JVC AC120V 60HZ NO. AV 27120 Any help would be greatly appreciated. I'm looking to determine if it is worth it to repair or purchase a new one.

SOURCE: On Timer light flashing on my TV

If you're NOT still under warranty you should at least open the TV and look for a blown fuse near where the power cable enters the set. A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace. Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs. good luck!

SOURCE: red lines across screen

wow this set has several problems that cause almost the same symtoms. There is a b+ filter cap off the flyback that supplys screen drive voltage th the crt that gets leaky and gets warm when the sets on. Also theres a resistor that feeds the voltage that gets warm and a cold solder connection appears but its dosent look like a bad solder connection so just resolder it. as a matter of fact most of those largewr resistors in this set causes all sorts of complaints soI resolder most of them just to stop any problems and a friend in the tv business still told me in one case he had an intermittant crt. and x ray protection cuircut problems.. Hope this helps GOOD LUCK

No! that is difinitely not an easy fix. there is something wrong with the picture tube. it is the part that emits light and colors. you need to bring that to a local repair shop.

hope this helps.

thanks.

SOURCE: TV turned off itself and timer light (red) keeps blinking

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Bright horizontal line across black tv screen


Hi There,
If your picture has collapsed to just a horizontal line across the center of the screen, this indicates that your Vertical Output circuit is bad and needs to be serviced by a qualified technician. I hope this helps and thank you for using FixYa!

TV: bright line across black screen for several hours.


vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch

JVC TV - BLACK HORIZONAL LINE ACROSS THE TOP OF TV


The vertical circuit is not pulling the top of the picture to the top of the screen (CRT) correctly. Its possible you have a loose wire or device ( after moving ) . If you have vertical agustments on the back , you may be able to adjust the picture taller; if the picture becomes stretched ( non - linear ) then you definately have tv tech only problems. At that point I'd really think twice about a repair and consider a new DTV or HDTV set. If the unit was damaged by a mover , then you may have a claim against them .

JVC TV 27" Black line on top of screen


This is for the original problem.. Not the second post.

It's a problem in the horizontal deflection circuit. The parts will be available, but you will be in for some daignostic repairs also to find out why it failing or if it has failed on it's own.
There should be a few caps near the IC (an LA7840) that could also be causing the problem. Click the link, it will make it easier to locate the part inside.

This is the kind of repair best left to a TV tech, but get it done now and it won't cost anywhere near as much as it will later.

It sounds like a vertical deflection problem. You mentioned you had a white HORIZONTAL LINE in the middle of the screen. If this line runs from left to right across the screen it's in Verticla deflection. If it runs from top to bottom, it's in Horizontal deflection. I am assuming the problem is a Vertical deflaecion problem. The repairs necessary are most likley to replace the vertical capacitors or the verticla deflection chip.
Good Luck

civilman, the first set has either no high voltage or is collapsed vertically, until someone checks for high voltage there is no concrete answer, the AV27730 is vertical collapse from your description, either the voltage to the vertical IC is missing or the vertical IC has failed, not a big deal cost-wise, hope this answers your questions, if not e-mail me back, good luck, BMW Rider

In the customer menu page thru it until you come to a page that has an item called convergence. move the cursor down to hightlight this and press enter. The next screen will have an Auto on the top line and a Manual of the second line. Hightlight the auto and press enter. The TV will attempt an automatic convergence alignment. BE WARNED>>>It will either correct it or make it worst. If it gets worst then the TV's convergence circuit has aged and is starting to fail. If it corrected it it's the same aging but not as bad, YET. If there is no change or it got worst then you will need to have the TV serviced preferbly by an authorized JVC service center because they have access to the service literature and buttetins.

I'll bet you have vertical output IC with some pins not soldered. This IC ( integrated circuit) is a "chip" that makes the picture fill out from top to bottom. After a period of time heat will cause the pins to crack loose on the circuit board. You need to have a tech check it for you. Stargazer

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.
