Question about Televison & Video
My screen is black now but 20 mins ago the screen had a blue and green line crossing the screen horizontally. the blue and green line was about 9 inches tall. once when i turned it on the screen was black with a thin blue line crossing the screen. this line was about 3mm tall and it spanned the whole width of the screen just like the last blue line. the speakers only work about 30% of the time and when the speakers have worked the screen is 100% black. the picture that was apparent with the blue line was not a signal in was just undistiguishable clolors. note: there is no antenna...could that be the problem? also the coaxial jack on the back has come loose from the shell of the tv but is still attatched inside. there was also alot of dust inside the contraption. does anyone think that they could diagnose this problem...if not my friend's step-father owns a tv repair shop. as a last resort i will take the television there for a diagnostic and repairs.

SOURCE: thin horizontal line
Thats almost definately bad solder connection. look at solder joints for cracks around teh lead. better yet, suck outold solder and put in new on any connections that have anything larger than a standard resistor lead. yoke plugs, tuner, etc

SOURCE: Tv not working
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!

horizontal line is an idication of a bad board known as a x driver board. Their may be a slight possiblitliy it can be a small ribbion cable that runs from the driver board to the plasma panel. Another possiblility it can be a bad panel... but from the symptoms you describe i would first have to look at that driver board. and the sympton that getting worse makes me lean toward a bad ribbion cable.. if that could be reseated....well that the first thing as a technician i would try. Carefull Television generate dangerous voltages.
