Hello,

its obvious that the the picture/display board of your TV is defective, that's why there is not display.

Of course, this will need to be repaired for the TV to display again. Despite the fact that its a new TV, electronics are very daisy as the TV may have a factory error that may have caused the display to damage so quickly.

I would suggest you take the TV back to where you bought it and replace it with another. Its too soon for a week old TV to have this type of fault.

I don't think it will be goo d you use your money to fix this TV.

Good luck.

Sharp TV (LC-40LE550U) without picture, but sound is fine. Very weak image with flash light. TV can be turned on with remote with green indicator.


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

I was able to fix this issue by changing the screen resolution to auto on the home theater system. Since I had no picture on my tv, I had to unplug it and plug it into another tv. Once connected to the other tv, I was able to access the menu and change the resoultion to auto (it had been reset to 480dpi, this is why it didn't work on my main tv). After I set it to auto, I was able to get it all to work. My niece had been playing with the button in front of the device and apparently the sequence of opening the DVD tray and pressing the stop button causes the screen resoultion to reset to 480dpi.

It means your PC video output resolution is too high for the LG monitor to display (your old monitor (CRT) can handle higher resolution than this LG LCD monitor), you need to set the PC video resolution to native resolutionof this monitor which is 1280 x 1024 @60Hz. You may have to use the old monitor (CRT) to set the resolution to 1280 x 1024@60Hz, then hook up the LCD monitor.

Sound but No Picture


Perhaps your remote is set to video recorder?  Try that first, and if no response, try calling up a menu on your TV and look for the Picture Settings.
Good Luck.
