Black and white lines running through the screen

If your set worked well (no lines, maybe only white or black scattered pixels) before you replaced the DLP chip, then your problem could be that the DLP chip did not get seated properly or the cam screws were not tightened enough after replacing the chip. The DLP chip must be seated properly in its socket or else line and column lines will be seen. There is also the possibility that the DLP chip is defective or suffered static damage while being handled during the installation. Hope this helps.
