Horizontal line in my TV.

There is a line about 3" down from the top of my TV set. Credits of a move or show roll over like the old black and white TV's my dad had. I know it is just a simple adjustment if I just knew how to do it.

    Hi,



    I have the same problem as describe. White horizontal lines at the top of the screen and a little roll over. JVC AV-24F702. I know it is a bad CAP but I would like to answer to be more specific. I use to be a TV technician but it's been a long time and I have no more manuals or schematics. The TV is at my friend's cottage and I would like to arrive there with the right caps value. Do you have few values to suggest?

    I have about 25 horizontal white lines across my F36668 from top to bottom. I can still see the picture but the lines tend to be annoying and make the picture brightness very high. I have adjusted the settings with no solution. Any ideas? Is there a way to "reset" the tv to factory settings other than unplugging for a time? Thanks

"Guest" obviously has no idea what he is talking about. There is no such thing as "frame section" and if the vertical IC, ramp generator or vertical hold circuits were bad, you would have no vertical at all. If you mean that there are thin white lines at the top 3 inches of the picture, and the top of the picture seems folded back on itself, it means that the pump-up capacitor is going bad in the vertical output circuit. This is a very easy thing to correct but should be done by a qualified tech.

If it is old model tv there is a problem in frame section. May be the vertical ic is failure or its ramp generator preset and vertical hold control problem. Change above components problem solved.

The controller board for the screen is going bad. check shopjimmy.com for replacement parts. It's not a difficult job to do. Once the back of the TV is removed, you'll see it near the center of the screen.

I have a Philips TV model: 27pt9015d. at the top of the screen several horizontal lines have appeared. it looks like the top inch is being cut off and then flipped back. that is - when credits are...


sounds like the vertical adjustment has spanned beyond the screen, causing it to jump up and then upside down. after the cover is removed look for vertical adjustment and with a non-conductive screwdriver, adjust it a little bit either way to see if it fixes it, if it doesn't fix it, then look again for the right one.

Wavy horizontal lines across the screen


It sounds that the main power supply section to your TV has the fault. The horizontal thik lines that appears crawling down across the screen should be of video 'HUM'. Have you replaced the main filter capacitor at the power supply section? If not, replace it along with the main rectifier. The AC power is rectifed by a bridge and applied ot this main filter capcitor. It will have a capacitance value between 120 to 350MFD 450VDC. Check this section. Measure the rectifed DC voltage acorss this main filter capacitor. It should be around 350VDC, if your home power supply line is 220VAC. If it is 110AC, this DC voltage will be around 165VDC; and it should be. If rectified DC voltage found lower than the input AC voltage, replace the rectifier bridge. In some sets, this bridge section have four diodes. Some other circuits, a bridge rectifier stalk may be used.

White horizontal lines at top of picture


Yes, definitely worth fixing. The problem lies in the vertical deflection voltage-doubler circuit. The usual fault is a single capacitor of 100uF/35V that has failed. It is normally connected to a rectifier diode right at the vertical IC. Replacing the capacitor (no more than USD4.00 in price) usually gets it working perfectly again. If you are finicky around technical work, then a reputable local repair shop in your locality should do it quickly for you and charge only labour.

Line accross top of the screen with flashing black and white boxes


Thin white dashes on top of screen is PERFECTLY NORMAL. It is nothing wrong with the TV, it is the broadcast. What you are seeing is the very bottom of the timecode running. It doesn't happen all of the time or all channels. It usually happens with old 4:3 commercials predating "Digital TV." This is mentioned in your Users Manual. You should be able to adjust the horizontal/vertical position in the menu settings.

Horizontal lines across the top 2 - 3" of the screen


Sounds like you have some capacitors that are needing to be changed in the vertical circuit. The cost I cannot quote but, it probably won;t be worth the cost as replacement TV's are much cheaper now. Zeniths and other brands for the longest time have used not controls inside the TV, they are technician adjustments through a service menu only.

White Horizontal Lines near the top of my Screen


this symptom is what we called vertical fold-over. vertical fold-over is characterised by a white horizontal bar on the bottom or top of the raster due to the concentration or compression of the trace lines. it an image is present, the bottom or top portion is fold over. this is caused by a vertical deflection current with poor linearity, which compresses the trace lines at the bottom or top of the screen. this symptom is is caused by a defective sawtooth wave genetator circuit, or improper biasing or defective feedback circuit of the vertical drive or vertical output transistor/ic. the negative feedback circuit in vertical deflection circuit compensates for the linearity of the trace portion of the sawtooth wave. a decrease in the capacitance of the sawtooth generator capacitor is usually the trouble. but if you do not understand anything what i have written here, better bring it to a qualified tv technician for your own safety also. good luck!
