White vertical lines in image w/ 2 inch black bar horizontal.

These thin white lines are vertical on image and are in proportion to each other. I tapped on the unit and the lines went away then came back shortly. There is also a 2 inch black bar horizontal through the image as well. Please help.

    I have thin vertical lines in an infocus In24. No horizontal bar however. The lines come and go with jiggling the projector. Any solutions? Thanks,

The black bar is from the light tunnel collapsing. the white lines are from the colorwheel or the main board has a cold solder joint. replace the tunnel and colorwheel and have the main board looked at.

Thin vertical line appears on projector


I have found that vertical lines that suddenly appear from projectors are due to poorly connected cables. Sut off your projector and wait for the fan to go off. Then unplug the connectors from the computer to the projector and secure them again, making sure to go all the way. Hope this helps.

VERTICAL WHITE LINES


I just read a post that said tap on the top and the line will go away. I tried it on mine and it worked! I had to tap it fairly hard. I just kept tapping harder and harder on the plastic in front of the buttons and voila! The vertical white line disappeared!

Thin horizonal line in middle on dark screen


The several thin white lines at the top of the screen is the warning that the vertical output IC is not getting the boost voltage it needs to run correctly. The IC cannot operate for long like that and shorts out inside, which is when the vertical collapses altogether and you get the thin white line through the center of the screen. The good news for your son is that he had nothing to do with that, and it has nothing to do with the cable F connector. The set needs to be serviced by an experienced tech who will restore the boost supply and replace the vertical output IC, and when I do that I charge $75 but techs in your area will vary, so be sure to ask around.

Thin Bright line is all I got on the tube


Sounds like a capacitor and/or the Vertical amp Ic has gone out in the set. Maybe a bad solder joint. Depending on where you live, the cost of repair could be between $100.00 to $150.00. Kill it or what? What would Braveheart do. FFFRRRREEEEEEEDDDOOOMMMM
