I tried connecting an HDMI cable from my Sceptre to my PS3. I only receive sound no picture. I navigate to Source PC and made sure I was set to 1080i in DVI mode. Then I navigate to Source PC / HDMI. I can only here the sound no picture appears. I tried to turn off everything and start over still no picture. I have my component cable working fine with the Sceptre and PS3. Maybe there's something else I need to activate on the TV? I'm not sure at this point .. The TV manual for the Sceptre 37" LCD TV is pretty bare. I'm going to call them today, but if anyone has success with an HDMI cable and might see something I'm missing here please let me know about it .. thanks.
