You can use nokia 6600 LCD IC (big ic under the lcd socket - 4041) inested of keypad IC of K750 that my friends say you that should rehot or change it.I tested it and work perfectly for me today.

I have a K750 with different keypad problem. Only key 3 is not working and when I test with tester there is continuity between the pads of this key.

There is no liquid damage at all on phone..

Any ideas anyone?
