Let me know if you have questions

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.

convergence chips bad

convergence repair needed

Ur Convergence is dead.Parts and labors,about $300 dollars.

chake to make sure it is hooked up right and not lose

I've seen this sort of effect on Sony, Hitachi, and Mitsubishi LCD projectors too. Its a defect in the LCD panels. The issue here is heat. The high temperatures around the lamp can go even higher when the ventilation system of the TV has been clogged by dust and other particulate matter, especially cigarette smoke. The lamination of the postage stamp sized LCD panels is damaged resulting in deformities which affect picture quality and uneven color rendition (blotches). Some manufacturers have helped their customers when approached and others have been compelled to because of class action lawsuits brought by angry consumers.

Since the set is only 8 months old, it should still be under warranty. This may only be an internal connection problem, but opening up the unit will void the warranty. I would suggest that you call for warranty service. This is a problem with the set and has nothing to do with external devices or interference.

Keep us posted.

check the yoke plug solder joint, as the squiggly lines in the middle usually happens if the yoke is unplugged. So check the yoke plug connections.

Check the regulator and convergences ICs....accordianman
