Question about Toshiba 43H71 43" Rear Projection Television
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.

Look through your manual. Your manual will always give you the most specific directions for your particular model. Look for an "adjusting convergence" or "set manual convergence" section.
