The power supply of your TV must be check.the power output of the power supply suppose to be 12 volts for audio,24 volts for the backlight lamp and 5volts for the main CPU. use a multimeter to measure the voltage In the case of your TV it seems only 5 volts is present that is why you have a power indicator lit....open the back cover of your TV and measure the power supply.power supply board is where the power cord is connected...

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.

If i turn off my tv it wont turn back on


This problem is either the TV's software or how the mainboard is distributing power so instead of just unplugging the TV, try a power drain:
1. Unplug the product's power cable so the device is not grounded to the house. 2. Press and HOLD the product's own power button for 1 minute to drain the capacitors. 3. Plug the product back into a wall outlet and try to turn it on.
Note: This procedure works with battery operated devices as well so remove the batteries and hold down it's power/on-off button.  Electricity can remain in capacitors and on circuit boards enough to prevent normal functionality. By clearing the residue electricity, your product will have a fresh start and many times this will resolve a buggy or non-responsive device that appears to be dead.
Since hardware either works or it doesn't, your issue is either software or power related since you can get it to work so hopefully the power drain will indicate further.
