Summary 0000098: the TP of band6,8Y is unstable
Description The TP of band1,8Y is unstable. The convertor of band1,8Y had been replaced
in the IVC at 20/01,2009. But the problem is still there, see 10900380.
Additional Information 20090301:
On Feb.12 the whole IVC unit of band1,8Y had been swapped with the unit of
band6,8Y. Now it appears the TP of band6,8Y is unstable(see 10900951,952).
So the problem should come from the IVC unit(but not in the convertor).
