Question about JVC AV-48WP30 48" Rear Projection Television
If you did not use heat sink compound then you probably have not hurt the new IC's yet but you should remove them and add the heat sink compound NOW. If the convergence IC's are bad then you will have access to the convergence menu but the adjustments will have no effect. The fact that you switched the IC's and got the same results shows that the IC's are good. If your red convergence is still way out when the new IC's are installed then the old IC probably burned out the low value resistor associated with the Red Vertical (RV) channel.

Sorry, I do not know the number or value of the resistor in that model, but if you look closely at them, one may appear discolored, the result of being overheated. Each of the 6 channels should have its own identical resistor, so you should be able to compare resistance readings with an ohm meter.

May want to check the circuit protectors on the power supply board

Replaced ICS with STK392-150's. Did use heat sink compound in back of ICS when replaced though. Would that have damaged the new ICS? Should I replace with new ICS (and heat sink)?
Sorry...meant to say did NOT use heat sink compound when ICS were replaced.
Thanks for your input, Mike. Do you know the number of the resistor I should look at?
