Question about JVC AV-56WP74 56" Rear Projection HDTV-Ready Television
Trying to remove the STK-392-110 chips from the TV to replace them. Screws are removed but they seem to be glued in. Any suggestions on how to remove them without breaking anything else?
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.

Hi, they overheated and are really stuck to the heatsink compound you will have to use a flat blade screwdriver and a hammer and tap them until they break loose, be SURE to remove the old white heatsink compound before you apply the new compound to the new stk`s, you did purchase a tube of heatsink compound for the new stk`s right? No compound = cooked stk`s in 6 months, good luck, video-tek

You will need desoldering braid or wick to remove the old solder from legs of chips, Ensure no solder is sticking any of the legs to the pcb.
Once done remove screws or clip holding chip to heat sink & remove the chip. If chip is stuck to heat grip it with pliers & work it loose then remove.
Remember to put new heat sink compound on the backs of the new chips when fitting.
