Question about Sanyo DS31590 31" TV

Tv not working

I have a 31/32 inch T.V that is maybe 5 years old. When I turn it on there is not picture. The sound works and there is a thin line that runs through the middle of the t.v screen that I think is the picture but the line is so thin it just looks like a line of light going horizontally across the middle of the screen. Is my picture done for or can I fix this?

This symptom, sometimes called the tube light effect, it is characterised by a bright thin horizontal line across the middle of the screen. this symptom is caused by a breakdown in the vertical deflection circuit. hence maybe the trouble maybe in the vertical oscillator, amplifier or output circuits. but if all i have said is not clear to you, better bring it to a qualified tv technician. good luck!

I got multiple thin colors on the middle of the screen


My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display issue (purchased Aug. 2008, manufactured July 2008). Vertical multicolored lines appeared on the screen just left of center. The band of thin vertical bars is 5.5 inches wide. The lines are about 1/16-inch wide. They are stationary, always exactly in same place. They over-ride any other picture on the screen (no transparency). They are there all time even with no video inputs to the TV after the unit is turned on. See picture #1. The TV works well in every other respect, but, obviously, it is annoying to watch the picture with the color band blocking about 1/6 of the picture.

I already swapped out the TCON board with no improvement and replugged the TCON board cables with no improvement.

Most likely it is the flat panel tab bond failure (panel made by Samsung). Further updates will be on my Facebook page.

32 INCH ZENITH PICTURE IN PICTURE ABOUT 15 YEARS OLD.PICTURE DISAPPEARED AND ONLY HAVE A THIN WHITE LINE RUNNING ACROSS THE SCREEN.THE SOUND STILL WORKS FINE. IS IT WORTHWHILE GETTING IT REPAIRED ??


When CRT TV's show only a white/bright line horizonatlly It is a failure of the flyback Transformer. Not all that costly to repair. Your old TV will probably still be working when all the latest plasmas and rear projections have been laid to rest. Fancy junk TV's dont get any better programs than those old reliable ones

Please rate my help++++Thanks for using FRIXYA
