I just bought a new dvd player and it references the hdmi which I know the tv does not have. Will it still work with this tv?

Flat screens normally have 3 different inputs from tv. Regular is tv coax cable, then audio/picture by using special rca cables, then last HDMI. You can use any of those inputs except hdmi because you already are using that input. You may be able to buy a hdmi splitting device that will allow both the tv and the player to input to the single hdmi input. Check Radio Shack or Wal-Mart.

Make sure your DVD player has HDMI or Component RGB output,you will also need RGB component cables or HDMI cables to connect the DVD player to your Vizio,once you have attached one of the above cables you will need to press the input button on your TV'S remote to select either HDMI or Component.

You have not clarified if you have made the correct assignments of the devices to the Onkyo.

For example HDMI IN1 = BD/DVD etc.

Refer page 39 of the user manual.

the hdmi output generally needs activating through the menu system. im assuming you havent already done this.
connect it with whatever cable works and navigate through to the menu system to select the hdmi output.
failing that it might be the hdmi cable is an older cable not capable of supporting ver1.3

Here is the manual:

When using the HDMI connections you may have to tell the DVD to output to that port.  Also you may have to connect additional sound cables from the DVD output to the TV.

hello kim , no Television told the rear of all TV have label the delcares what you own, like LG-LA55xyz123 see?
no DVD player told but is that HDMI cables used ? to the DVD deck?

the TV (most) have hdmi settings, and for sure sound. (TV end)
are all remotes used have fresh batteries.? if not they all fail.
if weak , and sure dead is dead but weak cause CHAOS in the remote. and TV. they need to be 1.5vdc each.
or a bad remote, (TV or DVD deck player) but is TV you proved that.
if you buy a new TV remote, be sure the old remote is batteries out ,decommissioned.
HDMI tricks, try all HDMI ports on the TV
in TV sound setting

in my LG I enable this.
HDMI ARC
HDMI-CEC (or LG Simplink) this turns on TV if DVD deck goes on .
no PC told , all answers for modern HMDI devices, all
not 3 cables or more to each device called analog cables. (relics)

It souunds like te TV is having problems with the streaming data being applied Most plasmas with DVI connections were actually designed for PC type input signals  Unfortunately the TV's input may not be able to stand up to the stream of signal the DVD or cable box wants to display. You can try and lower the output of both devices to 720P Good luck to you

It sounds like the HDMI port on the back of your Marantz is damaged. if you know for sure that the HDMI port works on another tv still you might just use component connection because the visible difference between component and HDMI is not very recognizable.

Are you using a HDMI to DVI cable or are you using a HDMI to DVI adapter? Sometimes, though not on all products you have to go into the menu and select which out put your using for each source and whats going through it. You might need to go into your dvd player menu and tell it not to try to run audio through the cable. That way it's not trying to force a signal through the cable that cant be accepted by the TV. That might possible solve your problem for the DVD player. Let me know if it works
Have a Great day

I have the same issue with this player hooked up to a Samsung 58 inch 1080p plasma.
