A1018 RF IC problem


Hi all. I have recieved A1018 with dead RF IC from customer, then I've changed it. In two days phone was returned to me with same problem. I've changed RF IC again and returned the phone. Now it returned to me again with same problem after two or three days of usage.
What can couse it's malfunction? May be someone had such problem.

Thanks in advance.

Common, man, it's an old phone. Replace whole board . . .
Ericsson phones are shi*ts, worse than Sagem phones . . . Replacing board is best way to "repair" those shi.ts
Sory

i've got T20 with same problem i changed the RF IC and after 5 days goes back to me again with same problem.
i think this RF IC must not get too much heat when put on the fones otherwise will kill the chip.
i tried put another new RF IC on this fones but this time with heat not too much on the IC. and i would like to see if this chip will go die again or not...
