Answer 1

Change your "Input Source" to the selection of the HDMI port (HDMI1 or HDMI2) you plugged the cable into.

Answer 2

OK, the consensus of most videophiles is that there is no discernible difference in picture quality between either HDMI or component, both delivering as fine and true and image as is available from the source be it a cable/satellite receiver or a DVD player. That being said, the advice most often given in this circumstance is to go component from your set top box to the TV and leave the HDMI connection for the DVD player.There are valid points for this but I'll present the most important first. Check the manual for your up-scaling DVD player and look for this most important tidbit. Most of the up-scaling players currently on the market will ONLY transmit their enhanced signal when an HDMI cable is used, component still allowing a picture but only at a standard resolution of 480p. This is not set in stone by any means as some players allow full 1080i transfer over either type of cable while others can be 'hacked' to transmit 1080i over a component connection by punching in a simple code accessed via the remote control, a handy bit of advice should one run out of available connection ports on the TV. Another factor in going with component from your receiver is rather simple to explain. A cable is only a conduit, a bridge between to units whose only purpose is signal transfer. It is not imbued with magical properties which allow it to enhance the original signal regardless of wheter the price tag was $25 or $150, at best it can only allow the data to flow with the EXACT quality and resoulution as was sent out from the source. How this comes into play during the decision making process is really quite simple and perhaps even worthy of a resounding "Duh!!!" How does the original signal GET to your reciever, what kind of cable acts as the super highway for all that data? Yup, just a length of simple coax, old as time and while reliable definaltly NOT to considered 'High Tech' by any strech of the imagination. Now if we are to follow conventional wisdom and classify HDMI as 'King of the Hill' in the cable arena then using it as a conduit to transfer a signal that arrived at the source via an obviously inferior conduit(coax) is just a waste of a good cable. On the other hand a DVD player to TV connection has no such flaw, it's a straight point to point type transfer. In theory this means that an HDMI should be the optimum method of said transfer as it is the 'Best' and this is a undiluted signal it has to work with. Sure, under most circumstances you or I neither would nor could detect the subtle nuances that MIGHT be had but hey, we live in a 'Better safe than sorry' world and so it only makes sense to follow such logic whether we can truly see a difference or not. Besides, it's what Mr. Spock would do and there's no faulting his logic! Well, I hope this information helps in your decision making process. It's what I've gleaned from countless AV forums and threads and is the combined wisdom of folks who seem to live and breath this stuff, those souls striving in the pursuit of the 'Ultimate' in the Home Theater experience. Maybe they Are geeks, I'm not judging. As far as I'm concerned everyone needs a hobby. Have a great weekend and happy viewing.

Answer 6

check if you have more than one HDMI input. some TVs have 3 or 4. if it's number 1 or you have only one, make sure the input is selected for that HDMI input. not for ANTENNA, not for AUX., not for CABLE. or it could be your HDMI cable. you might have to have the cable co.install a new HDMI cable.

Answer 7

Try input. Maybe you're not on the right connection. Input, select hdmi, or try the other ones
