My SONY 40" LED TV has no picture but has sound?

"@julzryu the very first thing you need to let us know is if the LED indicator is flashing red. If so, count how many times it flashes and let us know. If the LED indicator flashes red, reset the TV by disconnecting the AC power cord from the TV for two minutes, then turn on the TV.

Then start with the basics by checking the items as follows:

No picture (screen is dark) and no sound

 Check the antenna (aerial)/cable connection.

 Connect the TV to the AC power outlet (mains socket), and press / on the TV or remote control.

No picture or no menu information from equipment connected to the video input jack appears on the screen

 Press to display the connected equipment list, then select the desired input.

 Check the connection between

If that does nt work you need to check your power board and/or your mainboard. You also want to check the T-con board. First thing there is to check the fuse. Post some images of all of your boards with your question. For that use this guide Adding images to an existing question so we can see what you see.

If you do already have it apart, check a few things according to the SM"

First thing I would do and check is the connection from the board to the LCD. Not exactly sure where that would be on this model but it should be fairly simple to trace. Try reseating the cable as well. If it still does not work you probably have a issue with 1 of three things : LCD power / Image signal and or processing from the logic board / or a bad LCD panel.

More than likely to be faulty LEDs. Trouble is they are deep inside the unit and need to know where what is.

"Our Sony Bravia started flickering in the top third of the screen, then went black within minutes. Sound stayed on.

After unplugging power cords, checking connections, cycling unit, Still no change. At start up, Sony logo comes up then quickly goes black.

Having researched the web, suggestion was to use a flashlight on the screen at an angle to see if faint images could be seen. Found images were present. So further search revealed three faulty LED ribbons. Carefully removing chassis from screen, reveals the 3 led ribbons. I removed them and bench tested to find 5 LEds were faulty, at least one on each strip. Waiting for new replacements from Hong Kong to arrive. Hope this solves the problem."

Yes the LED backlight is faulty. Great care must be taken not to damage screen etc. Vince.
