2.Check Input Cables
Examining the input cables requires two steps: ensuring that all video cables are properly set, and then manually setting the display signal. Remove all video cables such as HDMI and VGA to the front of the projector Then, reconnect each cable in a series and check whether vertical lines go away. If not, go into the “Signal” setting in the control panel and select manually your video output type.
Check that you have cables have been securely connected to both ends.
When you’re connecting an extension cable it is possible to encounter interference if your cable isn’t adequately protected. You might need an signal amplifier to accommodate longer cables.

If there is only one line of solid vertical or horizontal lines in the image it’s an indication that one of the following is true:
1.) There is a problem within the DMD elastomer (socket that the DMD is seated in)
2.) Cable Connection Issues Between the DMD/Engine and Main ECA in which the DMD Control devices from TI are located.
3.) Possibly several affected DMD pixels (cluster) this is when the mulitpole pixels fail together. If this happens, it causes the row or column in the entoire to appear as an uninspiring line (off condition). If this happens the solution is to replace the DMD chip that is expensive.
