What's so difficult about putting in a text mode option? It's clear (two BIOS updates and still not working) that any automatic detection is dodgy at best.
The TV has _no_ options that apply here. There are no options to change. It's not a new TV, there aren't going to be any more updates out for it.
Simple (text) first then wonderful shiny bling (that I'll personally avoid anyhow) later.
That user had similar problems - which seem to imply that it's not a problem limited to my TV. This seems like several weeks of head in sand here.
