    The voltage has to increase OR decrease, in other words, differential voltage from point to point, the sign of the number needs to stay the same. Also, the symmetry test mirrors the voltages around VCOM (AVDD/2 or mid point average of gamma voltages) and sees if they match up. The symmetry test is an additional test, both should be done. It's a lot harder to do in your head. If either of these fail, the result is a guaranteed fail.

    Note -- the Detailed Results tab is more of an internal debug tab -- you should look at Summary for overall conclusion.

    New version coming soon with improvements and bug fixes.

        Flickering/double images and horizontal lines are panel problems but may be repaired with a workaround using the tape cutoff method.

            LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
            by Hakuu
            Hi There,

            This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

            After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

            More Details

            TV Model - LG OLED77G1PUA

            Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...

            LG 55EC930V OLED - swich on swich of no screen
            by maxim2511
            My Oled Tv is 55inch tv, 3 days ago I notice that middle of the screen is getting warmer and on picture I have ghosting, missing red color. Color red was still displaying, but it was not so strong as corners of the screen and watching some movies makes me angry.
            Then I get an idea to take it apart and clean boards from dust.
            In side of Tv was not so bad, I take compressed air in can, and gently blow up.

            Also I was thinking to styrofoam sponge to isolate power board from screen that the middle of the screen will not worm so much. Because Led on screen when gets higher...

            Lg TCon test pins for screen test
            by alltvrepairs
            Hi,
            i have a 65 Panasonic TX-65HX710E using vestel 17MB170 main and Lg tcon.

            Few drops of water fell probably near COF and have no display. Tried removing tabs but no.part of display present as if tcon fuse open. However 12v is present and tcon can be felt warm enough that supplies are present. Backlight and sound ok.

            Anyone knows if this TCon 6870c-0805A has any special test pins for rgb test?

            Appreciate your help....

            Hellow guys , i really need your help here.

            Lately i have a problem with My TL 866 II Plus programmer, and to be more specific many times on various IC ( Winbond, Gigadevice Mx) i get Check ID Error while i am trying to read the IC. Has already been detected without any kind of problem, but the only to read them is to uncheck every time the "Check ID " option. After that i can read it erase it and re-program it only to get another error at then end saying that can not verify the programing went well so i have program failed. So i am trying to find out what is going on? I...

            CH341a can erase and read but can't write and blank check
            by hasel17
            So I am trying to repair broken thunderbolt FW on X1 Yoga Gen 2. The EEPROM chip is WINBOND 25Q80DVNIG. I already do a back-up and erase. But when I try to wrote new FW, it was successfull, but when I tried to read it, it still blank. when I try to do a blank check, it gave me instant error in address 0. I already tried two CH341A, already did the 3.3v fix mod, using AsProgrammer, NeoProgrammer, Colibri, and CH341A 1.29. But the problem still occurred. What I did wrong here? Can anyone help me? Thanks in advance. Here is the log in Colibri :
