Use PowerShell to set TCP Port for SQL to 1433

Question

I've currently got the TCP Port in SQL Server Configuration Manager showing as blank. I need to figure out how to use PowerShell to change this to port 1433. I've been able to run this to actually get the value:

$smo = 'Microsoft.SqlServer.Management.Smo.'
$wmi = new-object ($smo + 'Wmi.ManagedComputer')

$uri = "ManagedComputer[@Name='" + (get-item env:\computername).Value + 
"']/ServerInstance[@Name='SQLSERVER']/ServerProtocol[@Name='Tcp']"
$Np = $wmi.GetSmoObject($uri)
$NPProp = $Np.IPAddresses.where({$_.Name -eq 'IPALL'})
$NPPropTCP = $NPProp.IPAddressProperties.where({$_.Name -eq 'TcpPort'})
$NPPropTCP.Value

However, when I run:

$NPPropTCP[1].Value = '1433'

I get the following error:

The property 'Value' cannot be found on this object. Verify that the property exists and can be set.
At line:20 char:1
+ $NPPropTCP[1].Value = '1433'
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: (:) [],
ParentContainsErrorRecordException
+ FullyQualifiedErrorId : PropertyNotFound

I figure this is probably something simple, but I'm stuck...

You have mistakes / missing things in your code.

Try this approach...
