I have a DC19 and the head will not release from the wand. The release button seems stuck?

A completely white screen with white vertical lines on your Mitsubishi WD 77731 TV can be an indication of several possible issues. Here are some potential causes:
  1. Faulty T-Con board: The T-Con board is responsible for processing the image signal and distributing it to the screen. If the T-Con board is faulty, it can cause the white screen and vertical lines issue.
  2. Loose or damaged cable connections: Loose or damaged cable connections can interfere with the transmission of the image signal, causing the white screen and vertical lines issue.
  3. Failed backlight: The backlight of the TV illuminates the screen from behind. If the backlight has failed, it can cause the screen to appear white.
  4. Damaged LCD panel: The LCD panel is the display screen of the TV. If the panel is damaged, it can cause the white screen and vertical lines issue.
To troubleshoot the issue, you can try the following steps:
  1. Check the cable connections: Make sure that all cables connecting the TV to the source device (such as a cable box or gaming console) are properly connected and undamaged.
  2. Power cycle the TV: Turn off the TV and unplug it from the power source. Wait for a few minutes, then plug it back in and turn it on.
  3. Check the T-Con board: If the T-Con board is faulty, it may need to be replaced. You can check for any visible signs of damage or contact a professional to diagnose and replace the board if needed.
  4. Check the backlight: If the backlight has failed, it may need to be replaced. You can shine a flashlight on the screen to see if there is any image visible, which would indicate a failed backlight.
  5. Contact a professional: If none of the above steps resolves the issue, you may need to contact a professional for further diagnosis and repair.

Samsung TV LN32A550P3F problems. About 4 minute after turning on screen displays some picture with vertical lines & a lot of louder white noise over the normal sound.

Please check sound on main power board. Could be a failing component that is heating and not functioning normally that is causing interference and thus the vertical lines.

Vertical line down screen

This problem can be caused by a lose connection between LCD and motherboard, however you can check it by opening the LCD or hinge bezel to ensure if there isn't any lose connection.

Flashing black and white vertical lines

Vertical lines in the display indicate a failing screen. New screens are expensive and not worth the labor and parts charges to repair it. It's new monitor time.

Colored vertical lines on monitor

Have you unplugged the power cord to the LCD? Let it sit for a minute, then try it. ALWAYS buy a UPS and plug any computer devices into it. Doesn't have to be big, a $50 unit will protect it from dangerous voltage surges.

Gateway laptop vertical dotted lines across the screen

Sounds like a problem with the LCD assembly or cable. You may want to reseat the LCD cable at the LCD end. It could be a loose internal connector in the LCD assembly.

White vertical line in the center of projected image

I have a Dell 2400MP projector that had the same problem of vertical white lines appearing over the screen.

This may seem like a simple solution, and I don't know if this will work for you, but the way I solved the problem was simply to press the bottom side of the projector, until the white lines disappear . Until now, the problem has yet to resurface.

Here's some simple steps:
1. Turn on projector
2. Connect projector to computer
3. Focus projector
4. If white vertical line appears, firmly press underside body of projector
5. See if vertical white line disappears
6. If not, try slowly pressing other parts of the body of the projector and see if white lines disappear.
7. If solution doesn't work, you may need to send it to the service center.

Hope this solution works for you.
