Can I view an operating instructions?

Since this is an older first generation (1999) HD TV it may not be compatible with newer HDTV receivers because the standards back then were different - Make sure the HD cable box is plugged into the HD component inputs on the back of the TV (not the DVD inputs) and that the menu setting on the TV is set to DTV (not RGB) video. This TV will only accept 480i and 480p signals on the DVD input. Also the HDTV input will only accept 480i,480p and 1080i (it will not work with a 720p signal,make sure your cable box is not set to that mode)

This could be your power DC.
I had the same trouble when I set the tv on its start normal.
but after a few min. the screens falsh on off, on off.
I change the adapter and the problem is solved!
Check this with a other DC power adapter.
I hope this will work. But for me it was the power DC adapter.

Dude, better check your cable and also your TV's power management settings. This might also happen due a issue with the HDMI output of the satellite box.
