Folk,

This is an arcane question of application rather than repair but I
don't know of a better place to ask.

I've connected the composite video output from a Compaq Armada e500
running Debian Squeeze, to a Panasonic LCD TV TC-20LA1. The display
on the TV works for the COMPAQ logo, the BIOS, and the console
startup messages. When X takes over, the TV appears to lose sync.
Nothing helpful is evident in the BIOS of the Armada.

My foolproof method for sorting out something like this will make linux
aficionados freak out in disgust, but here goes....

1. Temporaily install a Microsoft GUI operating system (Win95..Windows
7) including relevant driver software for the graphics card.

2. Attempt to get a decent picture on your TV with the above driver

3. Install powerstrip trial

4. Make tweaks as necessary using powerstrip
