Mitsubishi convergence IC replacement: this applies to sets that use (2) STK-392-570
The Idea here is to get the Middle Circuit board out so you can replace the Convergence Ic’s.
HERE is what you will need: (most of this you can buy on the internet or at local electronics stores)
Two new: STK-392-570 CONVERGENCE IC’S
One good soldering iron
De soldering braid or wick
Heat sink compound (grease)
One short Philips screwdriver
One small clean toothbrush
One electric screw gun to REMOVE screws
Turn the set on and examine the picture for how the Convergence looks bad---when you are done examine it again---once in a great while you will get and install a new IC that is bad. Remember this when you have finished—if the convergence is still bad but different from what you started with you may have installed a new I.C. that was bad. Turn the Set off.
