Hello,


IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER

Also,

All plasma an lcd ts have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them, but it is very easy to wreck em.

Good luck.

    Hello,
    having read your post try the following,
    the only to test this is to be sure the signal going into the tv is ok. so take the tv to the where your main tv is. hook the cable from the wall to the tv and see if channel is ok. i know the tv is not cable ready but it will work on channel fine without a cable box. if the tv works good here then it is either the box or the cable in that room.
    let me know what you find out?

If the vertical hold control have no effect, and can't stop vertical rolling, the vertical oscillator side should be checked. Check the hold control too, if any.

I lost the red on the screen


If you have no red at all let me explain: This rear projection set has 3 tubes in it. Red, Green, and Blue. There is a couple of problems that it could be. First, the filaments in the red tube may not be lighting up due to a bad connection on the board or module that connects to the red tube on the end of it at the socket. Or sometimes all that is needed to do is to reseat the circuit board by moving it slightly off and then back on. Otherwise you have a resistor that feeds voltage to the filament of the red tube or one of the plugs on the red circuit board needs to be reseated or soldered on the solder side

Hi = My LG5010 has developed vertical lines on the right hand side - if I move the screen backwards and forwards, the lines go away, but as soon the TV is switched off and on again, the lines come back. ...


The problem is most definately the LVDS cable that goes from the Main board to the Tcon board. The main board is the large one in the middle of the set and the t-con board is at the top- middle of the set. The connector is a long skinny plug with usually 20-25 pins. The connector can be unpluged (carefully) and cleaned with alcohol and a q-tip. There is NO VERTICAL Chip in any LCD or Plasma sets. Vertical circuits of that design have been gone since the inception of DLP, LCD and Plasma sets. The last analog set rolled off the line in 2005.

Have a 29 inch 5 or 6 yr old rca color tv lately we get a colored horizontal bar across the top of the screen and the other day we have fuzzy black lines across the entire screen


Hello,


CAUTION: To prevent damage to the CRT phosphors, immediately turn down the brightness so the line is just barely visible. If the user controls do not have enough range, you will have to locate and adjust the master brightness or screen/G2 pots.

A single horizontal line means that you have lost vertical deflection. High voltage is most likely fine since there is something on the screen.

This could be due to:

Dirty service switch contacts. There is often a small switch located inside on the main board or perhaps accessible from the back. This is used during setup to set the color background levels. (On some sets, this is located on the CRT neck board and may be a jumper plug or other means of selecting service mode - not an actual switch.)

When moved to the 'service' position, it kills vertical deflection and video to the CRT. If the switch somehow changed position or got dirty or corroded contacts, you will have this symptom. Flip the switch back and forth a couple of times. If there is some change, then replace, clean, resolder, or even bypass it as appropriate.

Bad connection to deflection yoke or other parts in vertical output circuit. Bad connections are common in TVs and monitors. Check around the pins of large components like transformers, power transistors and resistors, or connectors for hairline cracks in the solder. Reseat internal connectors. Check particularly around the connector to the deflection yoke on the CRT.

Bad vertical deflection IC or transistor. You will probably need the service manual for this and the following. However, if the vertical deflection is done with an IC, the ECG Semiconductor Master Substitution guide may have its pinout which may be enough to test it with a scope.

Other bad parts in vertical deflection circuit though there are not that many parts that would kill the deflection entirely.

Loss of power to vertical deflection circuits. Check for blown fusable resistors/fuses and bad connections.

Loss of vertical oscillator or vertical drive signals.

The most likely possibilities are in the deflection output stage or bad connections to the yoke.

The blue projection light is off, like it has dust on it. so unscrewed the front screen, cleaned the lights now the red and green are blurry looking. any help ?


You probably knocked or moved the focus lenses when you cleaned the lights (these are actually 3 picture tubes) Each lens has a wing nut that tightens to lock the focus in place if this was moved your focus would be off. Does the blue tube light at all? and when the TV's on is the image clear when you look directly into the Tubes? (the image should be bright and clear -not milky.)

Zenith picture problems


Your TV is showing signs of age. It's displaying something called "vertical foldover" which is due to capacitors in the set's vertical output section that need to be replaced. These failed parts can stress the vertical output integrated circuit, and if that goes bad your picture will collapse to a thin horizontal line. The capacitors themselves (usually 3 or 4 need to be replaced) are pretty cheap. A TV shop in your area (if there are any still around!) could fix it and the repair should be under $100.

By moving those rings on the tube's neck (which is actually the back) you have messed up the set's convergence. Those rings are magnets which adjust the electron beams in the tube so the red, green and blue images line up correctly on the tube face. The rings are often marked with a stripe after adjustment to show how they were lined up. Look carefully at them and see if there are any marks you can go by to reset them. To properly converge the set some equipment is needed to generate the adjustment test pattern. Again, a shop could do it for you.

All things considered, at this point you might seriously consider replacing the set. Not because the troubles aren't fixable, but because other parts can start failing because of age, and by now your picture tube is on borrowed time as well.

There are dangerous voltages involved here, and the best thing I can suggest is unplugging the set forever, as repairs can be made, but at a cost that may discourage your further use of the set.

I answered this to warn you not to attempt repairs yourself, as the capacitance (retained electrical charge in voltages in the thousands) retained on the chassis is enough to terminate any lifeform.

Please unplug the set.

First of all you need to find out which CRT leaked and replace it before any other repairs are done. The clear liquid is conductive and has done damage to the CRT board or boards.

RCA DLP/HDTV Vertical Lines


This is djb1 who commented above on the vertical lines that have gotten progessively worse. I may have found a potential solution. I unplugged the TV, took the back door off where you replace the lamp, took the lamp out, changed our vacuum from a vacuum to a powerful blower and blew ALL visable dust off anywhere that I could. I paid special attention to the heavy dust that was on the TV blower fan blades and around the mirror. I also held the blower on the outside of the TV on the vents around the lamp door.

After I plugged the TV back in, the lines have disappeared. We watched TV last night for about 2 more hours and the vertical lines never came back. So far this morning, the lines have not come back and it has been a couple hours as well.

It's worth a try. The free solution may be as simple as clearing out all dust. LET'S HOPE IT'S A PERMANENT SOLUTION!!
