Re: 43 APEX HA TV
it is necessary to replace 2 convergence Ic's associated resistors test and repair power supply voltages , then performed a convergence alignment all of this could be around $ 120.00 in parts. go to www.vancebaldwin.com for parts

No,ur tv have a problems known as a convergence problems,it dead.The tv convergence board must have it 2 STK convergence ICS and some or all it resistors must be replaced to solved the convergence problems.The shop will cost u $300-350 for parts and labors.
hello, the convergence ic's have gone bad in your tv . and sometimes they fail because of a 50 mfd @ 50v capacitor by each ic goes bad. if you have the skill at soldiering and desoldiering you may try repairing it yourself otherwise leave it to a qualified repairman. thanks .....techman...580-243-8025
Convergence is when you aim all three of the projectors, your tv has three, so that the images they produce all line up with each other. This usually doesn't generate a white line across the middle of the screen though, there is a button on the front panel of your set that automatically converges the three projectors, you can try using that.
The APEX and most rear projections are notorious for poor solder joints. The convergence circuits on your TV get very hot and the solder joints weaken over time. In your case, the convergence STKs are the large chips mounted to heat sinks right up front on the left hand side circuit board. Remove the board and resolder the STKs using a good low wattage iron. If this doesn't fix your problem try replacing the STKs. They aren't that expensive. They have 15 or so legs so you'll need some skills removing them. Good Luck!
