    Toshiba 47L7200U TV with thin vertical lines

    Hello everyone,

    Friend has a 2012 made Toshiba TV and all of a sudden developed these vertical lines top to bottom, all across. The colour is also off too.

    Here are a couple of pictures.

    I am not a TV guy but have dabble enough with bad caps and he asked me to take a look.

    Is this panel problem? Or main board problem?

    Doesn't sound like power supply problem to me.

    I have not opened it up yet to poke around.

    Thanks for any tips.

      Looks like a main board or T-Con issue. Does this TV have an LG panel or Sharp?

          I agree if an Lg panel it will be the mainboard if its a Sharp panel will be Tcon.

              Thanks for the reply guys.

              Since I have not picked up the set from my friend's place yet. I don't know what panel is inside.

              Maybe I can search for the Special code to enter the service menu and find out what panel is used?

              So panel is panel or T-con board?

              Main board could also mean bad news as not so much Toshiba parts I find.

                      And yes, the main boards are very tough to find for this one. My guess is that the TV has an LG panel based on what shopjimmy shows:

                      http://www.shopjimmy.com/toshiba-750...r-47l7200u.htm

                      That being said, it may be worth waiting to see if one pops up on ebay at a reasonable price. The only thing I see is a traded in service for nearly $200.

                      You can also check with pts electronics and see if they offer a repair service for your main board.

                          Found youtube video showing 3 different ways to get into Service Menu.

                          Unfortunately friend said none of them works.

                          I told him the one for LCD should work but he said he tried many times:

                          Press MENU on R/C
                          Highlight PICTURE icon
                          Press 9, 3, 0, 1
                          and service menu should appear.

                          He also tried the other mentioned methods to no avail.

                          Looks like I have to go over his place to take the back off.

                          So, if the main board is the issue, is it one of those BGA problem?

                              Panel is by LG.
