Hi I have exactly the same problem with IPOD Touch 2nd Gen, latest OS, Apple Universal Dock (A1256) with composite cable trying to get signal out to TV. The IPOD touch recognises it is connected to component on the TV and turns off the video on the IPOD touch, but just get a blue screen or intermittent diagonal flickering signal on tv. Admittedly its an old panasoic TV but the TV, cable etc used to work fine with my 1st GEn IPOD Touch.
Have also recently (since one of the OS 4 updates) been getting a message if using the dock to sync ipod 2nd Gen to IMAC that "This product is not supported".
Did you get an answer ?
