It is very common in many sets of this type that the electrolytic capacitors in the vertical deflection amp section start to go high in their ESR values.

An experienced TV tech can determine the defective capacitors and change them for you.

Is a Sansui DFTV275 an HD TV?


Is it possible that you typed the model # wrong? I can't find anything for that midel. If it has a hdmi port chances are it is 720p which would be hdtv. If not then it is most likely a standard 480p t.v.

Hi there My Sansui TV screen started showing thin white horizontal lines across the top of the screen. All of a sudden the screen starts condensing the picture into fine lines across the middle of the...


It is an indication that you have a problem on the vertical section on the main board. The faulty parts is the electrolytic capacitor which affect the linearity of the screen that's why you encountered that kind of problem.
I've advice you to send it to repair shop or look for a qualified technician to isolate the faulty electrolytic capacitor and do re-soldering for some dry joints on the main board.Once replaced the capacitor your unit will back to normal again.
thanks for using fixya...

I have a 32" tv jvc iart and horizontal white


Hello
You are seeing vertical retrace lines. This faut is due to the vertical output section inside your TV. To rectify this fault, you must open your Tv. Just open it after unpluging it from the wall power socket. Locate the vertical output section on the printed circuit board.
It is easy to locate. You can see four wires goes from the deflection yoke; the coil fitted around the neck of the picture tube. Out of which two of them will be thick, usually red and blue coloured, and the other two will be thin. These two thin wires are for vertcal scanning. Just follow these two thin wires, and you will reach a point where these four wires are pluged onto the main circuit board, very near to the LOT. Upside down the printed circuit board, and follow the print of that two thin wires, and you will reach to the vertical output section of your Tv.
Before doing anything, just look for any loose soldering or bad solderings there. It is very difficult to find out loose solderings, as thay will be microscopic, I advice you to resolder most of the soldering points there by applying a little more solder; without making any solder short. Resolder all the pins of the vertical output IC, and see the effect.
If this does not help, replace the two or three electrolytic capacitors, at about 1000MF to 2200MFD there, with same capacity and voltage ratings. Make sure about their polarity, as electrolytic capacitors have both positive and negative terminals like torch cells. Note the polarity when resoldering them out of the board. This must solve ypur problem.
If you need anymore asistance, feel free to contact me through Fixya. OK
Wish you sucess.

I have a 27 inch sansui television. It is about 5 years old and white lines have started to appear at the top of the screen. They are kind of annoying. Does anyone know what that is.


If your TV has a picture tube rather than an LCD display, you have a problem with the vertical circuit
(the circuit that "paints" the picture from top to bottom). Usually a capacitor in this circuit will open up causing this type of problem.

White lines on the top 2 inches of screen there


You Probably have some failing Electrolytic Capacitors in the Vertical circuit. it will only get worse and can cause the circuit to fail
all together if not fixed. Unless you are Electronically Savvy and know you way around TV circuits do not attempt to repair. Call a professional.

The original white line problem was caused by improper adjustment of the vertical size for which there is an internal adjustment. The current problem could come from two different sources, one an adjustment again, the other from a capacitor that is losing capacitance and gaining losses; = sick.
If you are fortunate enough to have a surviving TV repair in your area, none of these problems is expensive to find or correct.
Don't be surprised to find the only TV shop operating out of a messy garage since those of us doing this kind of service are dying off and the price one can charge for labor has shrunken to the point that a real business address is too expensive to have.

Horizontal line in my TV.


"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.
