6600 display IC is the same as 5200 Keypad IC. But are U sure ur IC is good? Try another IC. If not solved check Rap chip.

as you said sometime some keys are working sometime other are working after changing keypad ic. So your fault definately lies in the keypad ic and the 6600 lcd ic is the same as of the 5200 keyapad ic you can interchange them there is no doubt.As your post says , i think your fault must be in the keypad ic not in the RAp
Try with the brand new ic not with used ic, hope you will sucseed
Good Luck

That is right! I had same problem in 6680 once. Key 4 was working each time I used even brand new IC's but came back. After reheating OMAP problem was solved. You try reheating RAP.

Brand new ic may be faulti. Try original silver-packed ic or remove from a working board and reball it.

NOW I GIVE U A SIMPLE SUGGESTION TAKE OUT IC FROM WORKING SET LIKE NOKIA 6600,N70 .THEN MOUNT ON THE 5200 THEN U CAN CONFIRM IT HAS IC PROBLEM OR ITS PROCESSER PROBLEM.IF IT WORKS THEN MOUNT NEW IC TO REPAIR ON WHAT U ALREADY TAKE THE IC .IF U HAVE A GOOD SKILL THEN U CAN REPAIR BOTH SETS OTHERWISE INSTEAD OF ONE TAMPERED SET ,TWO SETS GOES DAMAGE.HOPE U WILL DO THIS..NOW I WILL WAIT FOR GOOD NEWS........
