      Check Tcon see if it has As15 Ic on it if so its that with out even checking voltages lol but you should check the output of the chip.

        Which one of the T-CON board you have? There are more than one model.

          Thanks to all for the fast response.

          ReeceyBurger123: I didn't found AS15 IC in the T-CON board.

          I'm posting my T-CON picture.

                Do you have tools to do surface mount repair? You may be better off getting the replacement board.

                  My plan is to get a replacement board, but I need and expert recommendation. I want to be sure the T-CON is defective.

                    At this point it's showing as bad T-CON board.

                          So how much is the T-CON board?

                              Sony Bravia KDL-40V2500 that will not power on
                              by PopsCaps
                              I have a Sony Bravia KDL-40V2500 that will not power on. The indicator flashes red 3 times.
                              I do not hear any sound and I cannot see any backlight.
                              I have tried disconnecting every cable on each board one at a time to see if anything changes.
                              The only change is when I disconnect AC-DET cable on the Power Supply board or on the other end if I unplug the CN7009 connection on the B-Board and try to power on the TV the indicator will stay on solid green until I power off.
                              My friend ordered another used power supply board but it is also doing the red indicator flash 3 times...

                              Sony bravia kdl-43w755c - boot loop
                              by justin35
                              Hello,
                              i have this sony bravia kdl-43w755c which boot loops. After sony logo, it shows the android animation loading then it restarts…
                              from what i read online it looks to be an emmc issue…
                              i’m not familiar with this kind of tv repairs… i’m repairing laptops and gpu’s…
                              i took out the board and say an samsung 16gb emmc
                              i don’t have an exact replacement, but i have a few 32 and 64gb emms’s from laptops…
                              i could try to put one instead of the 16gb one, but will it work?
                              where do i get the software from?
                              any help will be much appreciated!...

                              Trying to Save - SONY BRAVIA KD-75X780F - No Picture BUT there’s sound
                              by KYBOSH
                              Previous owner said TV just went blank one day.
                              They attempted to open the back panel and yanked the power connector off the power supply in the meantime.
                              Easily fixed that and got the TV to turn on. Backlights come one with everything connected. Good Sign.
                              The mainboard shows signs of life (red light on digital audio out is on) but that's about it. Good Sign.
                              There is not blinking LED and the most importantly there is LED response and sound when I press the MENU button on remote control. GREAT Sign.
