HDMI cable on Dynex DX-LCD37-09-2

Have you tried changing the video output settings on the PS3? It may just be on a setting that the TV does not support. For instance, if the poutput setting is 1080P, and the TV only supports up to 1080i, you would get a "not supported" signal. Hook the ps3 to a tv that it works on...turn it on, go to settings- display settings-output settings- select HDMI as the connector type- if it asks for 3D tv size...select the size- now you need to set the resolution...select all resolutions that the TV supports, since it is a dynex...it is likely a 720p TV. So I would start by selecting only 720p, and then hook the system to the Dynex TV and see if it works now. If it works, you can go back in and attempt to select 1080i or 1080p to see if they work... but again, being a Dynex, it is probably only a 720p TV... The PS3 is likely trying to output a 1080i or 1080p signal...which that TV doesn't support.

Try connecting directly instaed of through the switch box.

The PS3 can be hooked up to the tv using either a HDMI cable or the old RCA (Yellow, Red, White) cables. If you are having problems viewing a picture or hearing sound, here is some trouble shooting you might want to try.

Connect the PS3 using both the HDMI and RCA cables. select the HDMI input on your tv. turn on the PS3. If you cant see a picture, press and hold the power button until you hear 2 beeps (this will take about 15 seconds). This resets the PS3 to the old RCA cables. Select the RCA input on your tv. Hopefully you can see the image and hear the PS3 now. Go to the settings on the PS3 and change the display settings to output video through the HDMI. Remember, your tv can only go as high as 1080i resolution, so you wont see anything if you select the 1080p resolution.

If this didn't work, you might have a bad signal though the HDMI cable. Unplug the tv and PS3 for atleast 30 minutes, and then connect the PS3 to the tv before you turn either one on.

If this doesn't help, then you might have a HDMI cable that isn't recognized by either your PS3 or your tv. Try replacing your HDMI cable.

Hope this helps!

Do you get a picture at all? Its just not HD? The TVs ability to show HD depends on the source, it will not convert an SD picture into HD without the proper source. If you have no signal, make sure your using the correct input on the TV.

The tv Tuner signal board have problems,might need the replacement of the Tuner signal board it self.Tries the tv unplug,replug it back in like an hour later.Let the tv resetting itself back to the factory setting.See,if that solved ur problems.Not,than the Tuner signal board have problems itself,must be replaced the Tuner signal board itself.

you need to go into your console video settings and setup for hdtv to use hdmi.

I would suggest you check if your PS3 is set up on going through the HDMI Cable.On your PS3's XMB scroll to settings -> Display Settings -> ANd from there go down to the one that says "Y Pb/Cb Pr/Cr Super-White (HDMI)" and hit X and select the option Yes... That sets the PS3 displaying through the HDMI
If you are already have done that I'm pretty sure you know you have to change the Input on your TV to HDMI... Take your remote and hit Input -> Scroll down to HDMI on the Input Source menu and hit Enter when you get to HDMI
If the AV on your PS3 works and not your HDMI sounds like Display Settings issue...
If you have done all that, that is strange if it still doesn't work.
There are some people that are having problems with the AV Cable with the PS3, I tried this and it really does work. I switched from HDMI on one tv to a AV Cable on another and when I did that neither TV would display content from my tv. The fix for this is resetting your PS3, like on a iDevice you hold the home button and lock button, for the PS3 you hold the Power off button and the Eject button for around 10 seconds. This resets your PS3 into default video settings. Until it Turns on, Beeps, and Turns off. This should work.

Had the same problem.
Fixed by unplugging everything from the power source, leaving for 2 minutes then plugging back in.
Works fine now.

Have both the AV cables and hdmi cables hooked up from the tv to the ps3. On the TV Menu goto the av station which is different from the HDMi station...From the ps3 menu screen gotot settings then to video and audio and select hdmi then back to the tv menu and select the hdmi station and the ps3 main menu should be seen and you are all set

Same happened to my ps3 one week from new , took it back the the shop and got a refund.
