Very easy and cheap to fix. Go to Home Depot in the building section they sell magnets to pick up nails that fall off roofs,it cost about thirty dollars. Simply pass it over screen(it's OK to touch screen) very slowly. The great thing about this suggestion is that if it doesn't work, take it back for full refund. I sweep my scren about once a month. I have personally replaces my lamp as well as color wheel.

The tv has red images, I cannot get the red convergence line vertically to straighten, it is squiggly, the horizontal is straight, and the blue and green lines are both okay


the 43h71 has a pair of convergence ics that commonly go bad and cause this problem. replace original stk392-110 with stk392-120. the upgrades have a collector rated at 4 amps vs the 110's 3 amps and should be more reliable.

also know that they hyperboard in this set can cause squiggly lines throughout but will not affect the convergence.

Blue shadow and lines


This would apear to be a convergence issue ..sometimes you can go into settings and converge it manualy.. if this is to far out of range. a service tech will have to adjust inservice mode. if the convergence cuircits are not failing. if so then there are cuircits that will have to be replaced. is this just a blue shadow?.. is there green or red shadows. if not it may not be a major repair.
