> Hi guy's
> I went on service call yesterday for this projection tv.
> When turn on from cold, picture has no red only green and blue hues, if
decrease color intensity in customer menu has good black and white.
> Removed back and slid main chassis back a few inches for inspection and
customer said "hey there's color now"
> Suspected bad connection on a cable or board but could not get to mess up
again. Customer said she has had someone else look at for this same problem
2 other times and same thing said they just tightend a cable.
> I unplugged and reseated all cables from main chassis to drive and flex
boards on light engine as matter of course.
> This morning he called said picture was back the same, he says it looks
this way on all video inputs including component.
> What should I look for?
> Alvie says look at web site and check all cables.
> Well nothing on web site that refers to my complaint.
> TIA
