Question about Samsung HCN653W 65" Rear Projection Television
I'm fixing a Samsung HCN653W 65" rear projection TV. Right now, when pluged in the red LED blinks slowly on the front of the TV - pressing the power button has no effect.
I'm preparing to replace the convergence ICs, and they are STK392-040 - I have a pair of new STK392-150 ICs...can these be used? I know I have replaced STK392-110 ICs with the 150 part in the past...is it the same for the 040 series parts where using the 150 parts is just installing an uprated part?

The convergence IC's are large 2x3 inch(about) black in color IC's that stand up against a metal heatsink on the main printed circuit board. They will have white lettering on them that will plain as day when you see them. Make sure you replace these IC's with the manufacturers replacements and not some cheap copy, if the IC's cost less the 15 bucks a pop, they are cheap subs. Also do not forget the heatsink compound on the back of the new replacement IC's before you reinstall them. Good Luck

If you are removing a defective chip, can you just cut the pins carefully with a wire cutter and later apply heat to pull them off?

Yes the convergence ICs need to be replaced, however so dont the six 1.8 ohm 1watt resistors as Toshiba recomends replacing those six resistors when the ICs are changed. You can get the 50H71 / 50H82 Convergence repair kit as the 42H83 is identical to the 50H71 series, so the kit will work for your model. Heres the link where you can get the kit.
