I need a convergance chip but don't know where to get it


I learned today on my Mitsubishi VS-60621 (chassis VZ4) there are 3 convergence ICs (3, not just one as previously suggested), all 3 are STK391-020 located underneath the large heat sink on the upper right (as viewed from back of set), above the large PCB with the 6"x10" cover in the middle. The 3 chips are hanging upside down from their heat sink, have aluminum covers over them (so well hidden, it took me hours to find them, not knowing where to look), and the whole heat sink & chip assembly comes out by removing 2 screws, the front one must be accessed by removing the large lower front plastic cover and fiber-board piece behind it. Not necessary to remove the smaller plastic cover and control box above the big one. The big plastic cover has 2 large tabs on the bottom straddling the center post that will still hold it on once the screws are removed, gently pull down on them to release it. Not necessary to remove the glass doors, but probably safer to do so. Good luck!

Removing STK-392-110 chip


Mine came off easy because they hardly used any thermal paste at the factory (doh!), but dont be afraid to pry them off. You have to get the "glue" off anyway, just dont bend the PC board or crack an edge when you do it. Try clamping the heat sink gently in a vice and use a tiny flat screwdriver and twist under the IC. Once unglued, you can bend the ICs away from the heatsink pretty far as you de-solder the pins. I would recommend you replace with the higher power chips (150s) also. They are identical in function but rated for higher power which might get you a few more years of life.
