Question about LG 47LG50 47 in. LCD HDTV

1 Answer

I have an LG 47" TV (47LG50) that I bought a year and a half ago. It worked great up until now. I have three seperate HDMI ports (PS3, Cable and Blu-Ray.) It all off a sudden says "no signal" to all three units.

LG Tv M227WDL HDMI black screen


If the HDMI input is failing you will need to ring Customer Support or Get a New TV because if its not outputting then The HDMI may not get Prosecced (sorry about spelling) And make sure you have checked its the Correct port and that there is no Blue-Tac or dust in the port ( that ussually solves this) If all else fails Use a Hairdyer and give it a Big clean :D

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.

As you already checked PS3 and HDMI cable,
select HDMI input in TV and connect PS3 via HDMI cable. TV should show PS3 picture.
And if still no joy then HDMI input port in TV is bad and need to replace input board/ main board.
