Black and white picture with red lines vibrating with sound.


More info would be nice. Are you using HDMI or Component cables. If it is component cables (red, blue, green for video white and red for audio) Check your red and blue connection. Green alone will give you a black and white picture.
If you are using an HDMI cable, replace the cable to see if this changes anything or if you have another tv swap cables to see if problem stays with tv or moves to another tv.

Red lines are taking over


possible your tripler control is going out .This part splits the high voltage from flyback transformer into 3 high voltage leads to feed to the three picture tubes .The side for the red is likely to go out causing red picture tube to overdrive in red retrace lines..That or RED CRT BOARD is bad

Turn on pic turns red with thin bright red horizontal lines


Sorry to say, but that's usually the sign of a bad picture tube. One of the elements inside the tube shorts and you see the picture you describe, and the set shuts down due to high voltages getting to places it shouldn't. There's no solution except picture tube replacement, and that is uneconomical. You're better off replacing the TV when the tube goes bad.

Toshiba TP50G50 Theaterview picture is double with red color only


Your alignment is off. Go to the set up menu then convergence. hit right and you will be in the convergence menu. select the color that is not in alignment. The green line does not move. if blue and green are lined up the line will be cyan. if red and green are lined up the line will be yellow. when all three are lined up the color will be light. Best of luck!

My screen have some red lines


I will assume from you description that this is a rear projection crt(picture tube) tv. if this is true I have good news/bad news.
faint red horizontal bowed lines in the picture indicate the screen(G2) voltage for the red tube is too high.Slight lowering of the G2 adjustment will eliminate these lines. I stress SLIGHT because too much adjustment will mess up the gray scale .
The bad news the red crt made be bad. if the adjustment works but in the future the problem reappears then suspect the red crt.red crt replacement is probably not economical to repair.

Red diagonal spottted lines


These are called retrace lines they occur because of the blanking pulse not turning off the electron guns in the picture tube during the retrace period. Since this is occuring with the red gun there may be a proble with the video circuitry connected to the red electron gun of the picture tube. This would include the red amp and the red driver transistors. You will need a schematic and a multimeter to properly test these items.

A horizontal or vertical red line appears on picture.


Red lines are caused by glare. Avoid photographing shiny surfaces that reflect excessive amounts of light into your lens.
