hey, did you find the solution? having same issue

crwdns2893770:0crwdnd2893770:0crwdne2893770:0

yes.. it was T-CON board issue. i replace the T-CON board.

crwdns2893770:0crwdnd2893770:0crwdne2893770:0

Which tcon board was it? Pic please to show

@Emma Champagne

TVs only have one tcon board. The tcon board is the board that connects to the screen.

Depending on your model it may look like the one above with the red and yellow arrows on it showing the cables that connect to the screen.

Usually you can tell which one the tcon board is because the mainboard connects to it and it connects to the screen i.e. mainboard > cable > tcon board> cable(s) > screen

Had 2 vertical lines. Replaced with a new T-Con board. Restyle…No picture but had sound. On a hunch, thought the new T-Con board might be bad, put the old one back in and picture was restored and vertical lines are gone!

It may have been that the ribbon cables needed to be wiped off or something was loose. TV is working fine and it beats having to purchase a new one$$$

Dulan Wijesundara check your power board for bad capacitors and check the fuse on your T-con board. A failed T-con board can be a cause for a non-working screen. Post some images of all your boards with your question so we can see what you see. Use this guide Adding images to an existing question for that.

Update (11/08/2017)

Okay so since you do have the backlight that means your panel and your power board are most likely ok. That leaves you with possibility of a bad T-con board as well as a bad main board. Do you have a multimeter that you can use? Can you check the fuse on the T-con board and see if it has continuity and/or power?

Ok so "disconnect the LVDS cabel from T-CON board then backlight turns on" do you now still have backlight?

When you have it all connected properly, does your onboard menu still show up?

This occurs when the Closed Captioning is set to Text. Turn off the closed Captioning or select some other mode. Sometimes there is a button on the remote control with an icon on it that looks like two letter C’s in a box that does this. If not, you have to go into the TV’s menu and look in the Settings or Audio menu to figure out how to change the Closed Captioning settings.

@lena01 your answer is way off and has nothing to do with the question. You want to re-read the question.
