Toshiba 72HM195 Red Horizontal Line Over Picture

Watching a movie the other night a red (horizontal) streak started across the screen. To make sure where it was coming from, I disconnected the Blu-Ray player from the television, while nothing else was connected to the TV, I turned it back on and the red streaks where still there. I had another (new) lamp which I installed but it made (no) difference. These red (horizontal) streaks seems to appear more when there is brighter white areas next to dark areas. Also during some instances, it looks as if it is a pink/redish hue over the strongly lit portions of the picture other times during darker scenes the picture color is normal looking. The red streaks will be, sometimes, very small (not all the way across) other times all the way across and even full screen or multiples of 3 to 10 bars more or less. The picture is still there but when these red streaks exist they seem to be flashing fairly fast (as a constant blinking of your eyes). When red is over full screen and in larger areas it looks as if the picture was shot in a red light danger zone type of scenes. Sometimes in shots where peoples faces are fairly close their flesh tone in the highlighted places has a light muddy color look instead of normal skin highlights. During a lot of scences there is NO red streaking what so ever and ALL colors look normal.

I have a Samsung 50 in plasma tv that has sound but now picture. One day I was watching tv when the screen just turned into a horizontal thin red line across the center of the screen. Now I get no picture...


Your tv horizontal section is faulty change the horizontal transistor.or the diode that is at the leg of the collector of the HOT.do other checks around the transistor cause it can be more than one component is faulty in that section.also make checks in the power there is a diode that feeds from the pout put of tv regulator that might be leaking or is open.

My picture is doubled on my toshiba TN50V71 as if there is a shadow behind everything? Please help!


hi, sounds like a convergence issue. try this...
  • Look through your manual. Your manual will always give you the most specific directions for your particular model. Look for an "adjusting convergence" or "set manual convergence" section.

  • Enter the menu on your TV. Use the remote control and bring up the menu.
  • Choose "Convergence." This may be under "Picture Settings," "Function" or "Advanced Options."
  • Select a color. You will have red, green and blue to choose from. Do each one, starting with red.
  • Press "Enter." A crosshair pattern will appear on your screen.
  • Adjust vertically. If there is a horizontal red line visible, press the up or down arrow keys (or channel up or down) to adjust the convergence until the line is superimposed on the horizontal-center line of the white crosshair.
  • Adjust horizontally. If there is a vertical red line visible, press left or right (or volume up or down) to adjust horizontally. Do this until the line is superimposed on the vertical line of the white crosshair.
  • Save settings. It is important to save your settings when you are done, instead of simply exiting the menu.
  • Repeat these steps for all colors.
    good luck!

    Getting horizontal red streaks across printed page


    The drum roller is damaged. You must be careful and spin the cylinder. do not touch the roller. You probably have a line in the roller that causes this issue. Each time i have seen this problem, this was the cause.

    Picture on RCA TV shrinks to a horizontal line


    Hello,
    Sounds to me you have a cold solder joint ( loose solder connection ) on the printer circuit board around or on the vertical chip or on one of the vertical capacitors. You may also have a bad vertical chip or a bad vertical capacitor, but I doubt it since it did come and go. I'de get a soldering iron and some solder and touch up the connections. I will remind you that you need to always excersise saftey by making sure, before removing the back, unplug the TV from the wall, and use care not to come in contact with the large red wire going to the back of the picture tube as the picture tube can be turned off and still store lots of voltage ( up to 35,000 volts). Always stay safe and when soldering, use care not to run solder across places that will make a short.
    Good Luck and I hope this helps
