Output unordered list from a TV

Hello everyone,
I'm trying to display an unordered list from a comma separated Text TV.
I found similar post here, but I think it was coded for Evo. would appreciate any help.
The idea is that a manager user can add Red,White,Blue in the TV and the output source will be

<ul>
<li>Red</li>
<li>White</li>
<li>Blue</li>
</ul>

This is what I tried so far:
created a Text input TV, output default. [[*WallOptionFeatures]]

Then I created the snippet called [[wallOptionFeaturesList]] with this code:

<?php
$id = (isset($id))? $id : $modx->documentIdentifier;
$tvName = (isset($tvName))? $tvName : 'WallOptionFeatures';
$output = '';
$data = $modx->getTemplateVarOutput(true, $id);
$tv = $data[''.$tvName.''];
if (!empty($tv)) {
$values = explode(',', $tv);
$output = "\n <ul>";
foreach($values as $value) {
     $output .= "\n"  .  '    <li>' . $value . '</li>';
}
$output = "\n<ul>";
}
return $output;

and called the snippet on the page.
The result was blank page.
I tried cached/uncached or calling the snippet inside a chunk with no luck. always blank page. When called the snippet from within a chunk the actual snippet call was displayed, not the expected output...
Would anyone be kind to help?
Thank you.

for Revo you can try it this way:

<?php

$id = (isset($id)) ? $id : $modx->resource->get('id');
$tvName = (isset($tvName)) ? $tvName : 'WallOptionFeatures';
$output = '';
if ($resource = $modx->getObject('modResource', $id)) {
    $tv = $resource->getTVValue($tvName);
    if (!empty($tv)) {
        $values = explode(',', $tv);
        $output = "\n <ul>";
        foreach ($values as $value) {
            $output .= "\n" . '    <li>' . $value . '</li>';
        }
        $output .= "\n</ul>";
    }
}

return $output;

Thanks Bruno, but this only prints me the <ul> tag with nothing below it.
like so:

<html>
<head>
<title></title>
<base href="" />
</head>
<body>

<ul>
</body>
</html>

mind looking again?

fixed this line:

$output .= "\n</ul>";

does it work now?

not sure, if it is coming out as commaseperated list.
you can test that by

echo $tv;
