Verify if service is running on a list of servers

Hi EE

Does anyone have a script to share or can help me modify the one below?
I need the script to check a txt file and get me the status of a service on the list of servers.
The script below works but I need it to also output if a server on the list is not online .

$Computers = Get-Content C:\PS\servers.txt

$output = @()

foreach ($c in $Computers)
{
	$services = Get-Service *ServiceName* -ComputerName $c | Select Name, Status
	if ($services -eq $null)
	{
		$cinfo = New-Object PSObject
		$cinfo | Add-Member -MemberType NoteProperty -Name  "MachineName" -Value $c
		$cinfo | Add-Member -MemberType NoteProperty -Name  "Name" -Value $null
		$cinfo | Add-Member -MemberType NoteProperty -Name  "Status" -Value "No ServiceName present"
		$output += $cinfo
	}
	else
	{
		foreach ($s in $services)
		{
			$cinfo = New-Object PSObject
			$cinfo | Add-Member -MemberType NoteProperty -Name  "MachineName" -Value $c
			$cinfo | Add-Member -MemberType NoteProperty -Name  "Name" -Value $s.Name
			$cinfo | Add-Member -MemberType NoteProperty -Name  "Status" -Value $s.Status
			$output += $cinfo
		}
	}
}
$output | Out-GridView
