    Re: KDL-40S4100 lcd help please

    I used ShopJimmy's online store to deduce that the KDL46S4100 main board I got is most likely part number 1-857-092-21 (not the alternative 1-857-092-41). The System Firmware value of "V1.021,V1.008P" has the "21" in it (presumably the 1.008P is the actual version, which does match what the main menu says and which is older than the newest 1.115). Also, the serial number reported in the factory service menu is in the correct range for the 1-857-092-21 board.

    Thus, I can deduce from ShopJimmy's store that the LCD panel that the main board is expecting is either the 46" LTY460HB10 or LTZ460HB10. There is no cross-reference anywhere I can find that shows what "LCD_AU037_1920" translates to, so I still cannot tell for sure whether the "Panel Version: LCD_AU037_1920" shown in the factory service menu is the LCD panel that the main board DETECTS that it's attached to or EXPECTS to be attached to.

        LTY460HB10 = Samsung 46" FHD Panel
        LCD_AU037_1920 = AUO 37" FHD Panel

            Thanks, tom66!

            Whoa, that's crazy! Then the 1-857-092-21 board from a 46S4100 somehow got configured with "Panel Version: LCD_AU037_1920" even though neither the 40S4100 nor 46S4100 has a 37" panel in it. I wonder what happened...

            It is probably safe to say then that the Panel Version is what the main board EXPECTS to be connected to and that it does not autodetect what it is actually connected to.

                VIZIO E70-E3 Half picture with half TCON
                by Fly_Among_Stars
                Hi,
                I have a VIZIO E70-E3.
                Symptoms: Black screen, no picture, but LED backlights are working.
                I probed the power board and voltages are as listed on the board.
                Main board appears fine, too.
                I believe the problem is either a bad T-CON board, or connection to LCD, or bad LCD.
                There are two separate ribbon cables feeding the LCD.
                If both are connected, the screen is black.

                If only the ribbon cable that feeds the right side of the screen (when viewed from the front) is disconnected, the left side of the screen shows picture and...

                Samsung LCD TV no picture backlight on no 12v at tcon
                by shelby5041
                hi
                i have a samsung lcd tv

                it powers on with sound and backlight but no picture

                all voltages from PS are good 12v 3.3v and 5v

                whats odd is that at the tcon i tested voltage across the fuse on the tcon and i get 0v

                i figured main board issue..so i ordered a used main board....when i put replacement main board in i still have same issue

                no 12v at the tcon fuse

                i disconnect the panel ribbon cables to rule out any panel issues and i still have no 12v at the tcon fuse

                the odds of having 2...

                TCL 50S535 bad tcon or panel issue?
                by x_orange90_x
                Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...

                T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)
                by Tr0ll
                Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

                The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

                Original T-con:
                Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

                First replacement T-con:

                I thought it might be t-con and ordered new t-con from china(supposedly tested)...

                SAMSUNG UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
                by JJAAMM
                This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

                Problem
                TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...
