The line above is the issue.
How is your TV connected to the board ? Composite ? S-video ? RGB ? 
YCbCr ? Also, what is configured in the bios for the TV output ? Does 
that match ?

There's still something weird here, but it might be a difference between 
VT1625 and VT1625S.

This is not expected to work. I suggested to force the VGA port 
detection because there is a known problem with DVI-A, which can be 
worked around with such a hack. The TV port is a different story.
