t28 signal problem
 

T28 has signal problem, when try to make a call signal drops,
I also have samsung A300 dead, any ideas ?

For T28:

Replace RM 009.

1./T28 There is Inductor under the PA. Check it.
If it's gone replace first PA after that it.
If that inductor is OK just rehot PA.

2./A300 it can be from power supply circuit or from eprom.
Try to rehot eprom.Try to read eprom and see what you read.

Thanks for help.

T28 problem has been resolved by resoldering RM009/PA chip.

A300 problem is still here, i have checked eprom which is ok.
