If you think the back light is working then check out the main board since you have no pic and no sound.

I have a 47 lg lcd tv bought in 09. When i use hdmi for xbox 360 i get picture and sound but with ps3 no pic no sound. I just bought a sony bluray and get pic but no sound. I bought a lg bluray and get no...


To clarify, your TV is working correctly, since you get sound and video from all devices - Only your PS3 has no sound or video?

If your PS3 was previously used with regular AV cables (Red/White/Yellow) then you most likely need to do a PS3 video reset t output video over HDMI.

With the PS3 OFF, press and continue holding the power button until it turns on, beeps twice, and then turns back off. Do not release the power button during this process.

You may have to try the video reset a few times if it doesn't work right away.

After video reset, you should get sound and video over HDMI.

PICTURE AND SOUND KEEP GOING OUT AND COME BACK FOR 30 SECONDS


One of the power supply areas are most likely going intermittent. This can be from cold solder connections on the circuit boards, or from some components failing due to age.

An experienced tech should be able to service your set, but it will be expensive for the time involved. Sometimes these types of faults can be very time consuming to resolve.
