Sound doesn't work in HDMI mode, just picture. I tried buying a new HDMI cord but that didn't work either. Then one night the TV just turned off and now it won't turn back on.

How you would fix a black or blank screen on your TV.

1. Ensure that the power sources for all your devices (TV, digital box, VCR, etc.) are securely connected to your devices and the outlet. If that doesn’t fix it,


2. Check that your TV is set to the correct input. If that doesn’t fix it,


3. Unplug the power cord from your digital box, wait for 30 seconds, then plug it in again. Wait until the box has fully powered on again, then see if the picture has returned. If that doesn’t fix it,


4. If you have an HDMI cable connected to your TV, you could try an HDMI handshake.

your tv has a bad power supply module. with the model and serial number look it up on ebay, they are like $60. buy a new one and replace it.

Your problem is in the TV. I'm not familiar with your TV, but you should look for an option to turn it to normal or to try and scan for channels with xbox plugged in and running. I'm pretty sure that if you get HDMI cable, your problem should be solved.

I have a 42in vizio led with about the same problem i replaced a 75 cent chip # u33 on computer board problem fixed.

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!

Tries tv and cable box unplug,replug it back like about an hour later.For the tv to do a resetting itself back to the factory setting.The cable box to reboot and upgraded it software.Than go in to the tv Menu go to Audio Setting go down and do a resetting back to the tv factory setting.By doing these steps u have a great chances to get ur tv audio sound back.Not have the same problems after this than the tv Tuner signal board it is shorted in the audio ICS modjulation sections.Tries websites like Shopjimmy,com,Ebay.com to buy a whole refurbish tv Tuner signal board for the replacement.

HDCP is the "handshake" protocol used by the Xbox to communicate via HDMI to your TV. The optical cable wouldn't have anything to do with this error. So far the only solution that's been found to this issue is to ensure that the HDMI cable is properly plugged in and power off/on both devices and see if the handshake is restored. If this doesn't work you may need a new HDMI cable.

Your PS3 may not be in HD mode. When you turn on your PS3 hold down the button until you hear a series of beeps. This will switch the PS3 to work with your HDMI. Now turn off and turn on the PS3 normally and you should have video.

I may be wring on the steps so check your manual or reference:

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.

it happens to me alot lately i think its the actual hdmi port of the ps3 just unplug the hdmi cable and plug in and it should work just fine.
