Help Fixing UT61E MultiMeter continuously beeping

[pharaon]

ok done got you the voltage , it was mess to find the right pin each time
17- 0.02V
18- 0.0V
19- 2.97V
20- 3.01V
21- 3.01V
22- 3.01V
23- 3.01V
24- 3.00V
25- 2.98V
26- 2.71V
27- 0.00V
28- 0.00V
29- 0.00V

37- 1.21V

For example pins 23 ... 26 are inputs for voltage measurement. Without voltage connected to the meter's input terminals I'd expect 0 V at these pins. According to the datasheet chapter 1.2 a full scale voltage of 22 mV is to be expected when the input voltage is at the maximum for ach range. With 3 V at these pins it is obvious why the meter displays overload.
In the schematic I see no way these voltages can be present other than a defect of the chip U1. I'm afraid the chip has been toasted by your initial wrong connection.

i understand
and I'm really grateful for your help and effort
