Member: 78543 Status: Offline Sonork: 100.1603369 Thanks Meter: 25 | 7610 broken contacts from PCB  Contacts from #16, 18, 19,20,21,22,23, 24 are broken from PCB so there's no way to put them back in that place. I was thinking of to tako wires and drive contacts directly from LCD to places where they should be. I've also found that they should be on Z402 , but now I'd like to know what to do? Should I take off Z402 from PCB (with hot air) and then connect LCD contacts where they should be, or is there another way to connect LCD contacts at some other place (that I don't have to take off Z402)? Hope you understand me!  Thansk a lot! Best regards, Igor |

Member: 78543 Status: Offline Sonork: 100.1603369 Thanks Meter: 25 | Hm, now, i have only one more question... Is it sure to take off z402? does it have some kind of protection, maybe I shouldn't take him off? and Is it possible to connect all contacts on such small space?  BR Igor |

and there is no more further protection as z402 is the ESD filter , but you need to use a very thin soldering tip . | |
