my Roku is getting power but when it's hooked up my tv, my tv reads no signal. I have tried the other HDMI input slot and same thing. I have hooked other devices up in the same slots and they work just fine. HELP
As I understand it, you took this Express from another working TV and then plugged it into this TV (LN32d405e5d) so it never worked on this TV before.
From the manual, I think the only setting that may help you is to Reset the Picture Settings assigned to HDMI 1 and HDMI 2 (pages 14-15) This is the only stored setting area for external devices. Could be the previously stored settings are causing a conflict with the Express preferred settings.
