Default LG TV Main Board Main CPU 42PT350

Last week we had bad weather and I have had 4 LG TVs come into shop. I replaced two main boards. It seems LG main cpu are very sensitive. I cant find schematics for many of the boards to find out the actual part number off the chips without removing the heatsink. Does any one know a source for the main IC chips used on LG TVs ? Is there a list some where that tells you what TV used what main IC ? Has anone sucessfully removed and install new ICs?
It seems a waste because the main CPU fails and the rest of the board seems good. The main ICs temp when failed all are in excess temp of 155 F.
IC1 has failed on EBT61712701 main board.
Thanks
