I have tried a search, but to no avail.
I have a lilliput 629 that has been running fine for a long time, but just recently it stopped working. It defaults to composite video and I cannot switch it to vga. If i push the change source button, it acts like it is going to switch, but then just comes back to c-video. I don't know anything about the insides of these monitors

so I have to idea what would cause the monitor to not be able to switch to vga mode.
Any help is greatly appreciated.
