    samsung le40a656a

    Hello guys

    so i picked up the tv today with solarized images cleaned the lvds cable and reseated which made the tv picture go ten times worse,upon cleaning a second time to the tv would just keep restarting so tried a third time and now everything is ok picture is fine

    intermittent fault somewhere or is it just tricky getting the lvds cable right sometimes ?

    thanks

    Could be main board fault-- I would run it for some time before calling it fixed. Not encountered dodgy LVDS on models using the "rigid" cables myself; it's always the flexible ones that are failing.

    I had a non-intermittent LE40A656 picture fault, bad T-con board. Mine was a repeated pattern across screen, every other 1/8th of screen was solarised. https://www.badcaps.net/forum/showth...light=le40a656

    I've also had bad tabs cause a dark blurry pic but I'd guess that's not what you've got.

        Try pressing on that black heatsink to see if the same thing happens.

            While you're at it, worth cleaning the fan as it can make a loud noise sometimes while operating.

                  It is for EMC/EMI compliance. i.e. radio interference. Not a major issue, just try to stick down as much as possible.

                      It should be ok... just be more careful next time.

                          • Samsung 2x red blinking standby LED = panel fault
                          • Jumpered FB_TRDY_1 (pin 1 CN1300 left. main tcon->left side buffer boards) and FB_TRDY_3 (pin 95 CN1301 right. main tcon->right side buffer boards) This allows testing individual T-Con (on main board) connection to panel on this Samsung. Found fault on left side (viewing from rear of TV)

                          by NolesFan
                          Hello all... TV started boot looping. Opened the back panel and tried to isolate the problem. Just PSB no boot loop. PSB and MB no boot loop. Plug in the LVDS from panel to MB and boot looping starts up. It doesnt matter of order that I plug the LVDS ribbons back in, only 1 and no boot loop but as soon as 2nd one plugs in boot looping. I then noticed a flicker on the screen when I was closing the clip on the harness to the LVDS. Shut the lights off so I can see better, and I noticed as i slowly close it, I will get a picture, but as soon as it clips in, I lose picture and booting happens. So I...
