SOURCE: lg lcd tv screen goes

I had this problem on my 42" Philips. Just got it yesterday and worked fine on the tv stand. As soon as I mounted the TV to the wall via wall mount system, I had the exact same issue you did. Figured it out today.

The wall mount was putting pressure against the center of the back of the tv (tv set had a slightly rounded back plate, and the mount was a flat plate). As soon as I put spacers (part of the wall mount hardware set) between the wall mount braket and the tv so there was no contact except at the mounting holes, the tv worked fine.

My theory is the pressure pushed the tv back plate against some board components which caused them to overheat (no air flow); or put pressure on internal connectors. I dont know.

Hope this helps, may not apply to your situation.

Blu ray shows the "Blu ray Disc" Logo on TV screen and then just show a black creen

Hi! and welcome to Fixya!

It looks like your tv is unable to handle the output video resolution from your bluray. The reason why you do not have picture on the tv screen after the bluray disc logo appears.

You can follow the instruction below to set the video resolution on your player to its lowest resolution:

1. Using your bluray remote control, press the following buttons in order... STOP button (press and release) ....HOME button (press and release)....POP UP/MENU button ( press and release )
Note: press the buttons in order with 1 second interval. Make sure tv and bluray are ON when you try this. If first attempt nothing happens, try this again.

2. When the home menu screen appears after doing the above instruction, you can set the video resolution again manually. Follow the instruction:
Using the BD remote control press HOME button > then go to SETUP > select screen settings > then change OUTPUT VIDEO RESOLUTION to Auto > change also 24P OUT to 1080P // set the BD-ROM 24P OUTPUT to Auto

The next time you turn on the bluray player you will have picture again.

Let me know if this works!

you may need to change the HDMI board in the tv. it will be the hole board the parts are just to small to replace them all to get the HDMI board working again. find a second hand replacement. should be fine with another known working one.

You don't say what you are trying to connect via USB. The DVD USB ports I've used only support FAT32 format. I get that black/then logo screen if I try to connect a NTFS formatted device.
