NO SIGNAL ON HDMI PORT

TV turns on but says "no signal". Tried PS3 on different HDMI port - no signal. Tried HDMI outpuits on different TV, and the devices are working. It seems as though our HDMI ports took a dump. Any other reports of this?

SOURCE: "No signal" sign on TV screen using HDMI selector

it sounds like a refresh issue, double check you selector and make sure it fits the refresh of the tv. i had this once with a sharp where the tv was 120hz and the selector was 60 and it created a no signal and when it did come in it was jumpy. if you have a 120 tv then selector should be the same.

Are you aware that all the new HDMI devices have interactive technologies . For eg: if you are watching cable TV and switch on your Blue ray player connected via HDMI, you will notice the TV will automatically switch to that HDMI input with you having to pick up the Tv remote and switch manually. Some find it irritating, but you can disable that function in your system Menu. Panasonic calls it Vierra link / Sony calls it Bravia sync etc.....

Hello
Unfortunately your TV is only HD ready. This means that it plays video in 720p. A full bluray disc is 1080p. Im afraid your tv will most likely not be able to handle a bluray player.
:( sorry
Hope this helps

It is because the PC video resolution is too high for the TV to display, you need to set your PC video resolution to the native resolution of this TV, see you owner manual.

Ps3 turns on but no signal on tv


Hi There,
Is the TV set for the correct input?
I assume you are using HDMI?
If all settings and input selections are correct then I will have to say that either the HDMI cable is faulty, or the HDMI port on either the TV or PS3 could be faulty.
Check if PS3 can work on another TV with the HDMI cable.
Check if another Device can work on that TV with the HDMI cable.
Try another HDMI cable.
From this, you should be able to determine where the issue is sitting.
Hope this helps!

Samsung TV Is Not Picking Up A Playstation 3 HDMI Signal


If you are able to connect your PS3 to another TV using the same HDMI cable that would rule out your PS3, if it works.....or
does the PS3 itself have any settings that perhaps need to be set to an HDMI output as opposed to Composite or SCART etc?
Also have a look at the HDMI settings in theh TV menu too.

I plugged in my PS3 using an HDMI cable and i get no feedback


If you just bought the PS3 use your composite cables that came with the system. Turn the PS3 on and go to the video settings, set up video input to HDMI. After you've done that plug your HDMI back into your PS3 and try turning it on. If that works go back to video settings and change the resolution to 1080p. If that doesn't work make sure your T.V. is on the same input that the HDMI cable is plugged in. If it is and still doesn't work try switching to a different HDMI port. If switching to a different HDMI port doesn't work try a new HDMI cable. If the new HDMI cable doesn't work then there is a problem with the port on the PS3 which would require a repair.

No signal through hdmi ports


Check the hdmi cables be sure their in proper working condition, wiggle the cables around see if picture comes up. If not and the cables are good then the hdmi processor on the main board of your TV is defective. Alot of times hdmi ports tend to burn so see if you smell a burnt smell near or around the hdmi ports. but before you do anything be sure sure your TV settings are correct for hdmi....
