if so, you may be out of luck.
as far as im aware, the only way to convert a digital HD signal into an analogue HD signal is through the use of a very expensive upconverter.
since you are trying to put the wrong kind of signal into your tv, a normal socket converter is not going to work. you need something to actively convert the signal into one your TV is capable of decoding.
Just realised i think the TV is 30Hz? If so i must set the refresh rate down to match correct? This may be why there is no picture, but i have no other DVI adapter to connect the monitor at the same time to attempt to adjust. Blah. =(
i would be mighty shocked if they actually make HDTVs that run at 30hz.
im pretty sure the problem is as i stated before, you are trying to put a digital signal into an analogue intput. the TV is not capable of decoding it, and so does not display.
you need something capable of decoding the signal into analogue, but thats expensive.
