Which ASD test shows that error?
Each test is resumed in 3-4 message lines.

BTW, set On Error mode to Continue before start ASD test.

I changed U5510 and found p1 : 3.1V and still its cursor is moving slow. So is it right 3.1 V?

You still have corroded traces, or resistors.
Check U5510/20 area and continuity to their sensors.

Checked U5510/20 area and continuity , all are good . any other idea.Thanks.
