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.

It started out with alot of different colored squiggly lines it would clear up after about ten minutes but it just shut off yesterday the red button on the front still flashes though


Especially Projection TVs will shut down to protect the projection tubes because loss of proper scan can burn an image into the phosphors in the tube itself. The squiggly lines most likely are a symptom of a failure in the Horizontal output section (the part that scans the picture from left to right), there is also a possibility of the Vertical output section (the part that scans the picture from top to bottom causing the problem. This will require replacing a circuit board or repairing the one in the set at a component level. This is best left to a qualified Technician to do the work.

Squiggly Lines at Power On


Generally speaking, this type of symptom is caused by AC hum leaking throught the power supply. This can be due to a bad filter cap. Since this clears up after a while, I'd start by looking for poor solder connections in the power supply area. If you can, check the caps in that area as well. I'll research this a bit and try to get you more details.
