Change both IC's at same time is SOP ( standard operating
procedure) Note: Poor soldering from factory can lead to IC
failure, so, at the very least, hand solder all pins.....
Verify which is red chip by Service literature or follow red plug-in
traces to red IC.................................T.

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.

Stk392-110 verses the Stk392 -118


Not a correct sub.......Tosh STK392-110 subs to STK392-110T.

If you want a true upgrade / sub = -110 to STK394-160E.....I use
Hitachi brand = best OEM choice.........

Do not use generics = they are seconds,poor quality,won't last
as long as first quality........................T.
