        For i = 0 To areasback.Count - 1

            If chklistInput.Items(i).ToString() = x.ToString() Then

You have to loop over chklistInput.Items.Count - 1 instead of areasback.Count - 1

use the following code:

Dim areasback As String = DataGridView1.Rows(0).Cells(6).Value.ToString
Dim areasback1 As String() = areasback.Split(",")
Dim intCount as integer = 0 

For each str as string in areasback1

    For intCount = 0 To chklistInput.Items.Count - 1

        If chklistInput.Items(intCount).ToString() = str Then
            chklistInput.SetItemChecked(intCount , True)
        End If

    Next

Next

chklistInput.Refresh()
