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 |
brth replace the ic with new one and rember to use good paste to change ic [like orignal amteck flux volume 10cc]some time when we change ic it works for few hours but after few hours problem come again....this fult is also come through bad paste whic uyou use to change ic..... godd luck..:cool: |
USE GOOD SKILL WITH GOOD EQUIPEMENTS, UR PROBLEM WILL BE SOLVE.ACCORDING TO U UR PROBLEM IS IN THE IC .JUST CONCENTRATE ON UR WORK |

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........ |
i change altleast six new ic's but now only 1 and 3 r not working as it work for some time then again it stop working and all keys r working with all ic's but after 10 to f15 menit 1 and 3 stop responding all other r working |
