    Re: Buffer size not equal to IC size

    actually one problem i noticed, after the 3.3V coil, i have a cap, and somehow after the cap i have 6V. is that OK?

      The chip is 10MB in every single software i tried even without the programmer pluged, so it's not the software and probably not the chip
      I just don't understand how the reading was 16 if the chip is 10.

      and what in the name of god is the actual bios chip?

      I have the same problem.. I'm trying to bring to life a dead lenovo yoga S740 with the ch341a programmer! the problem is, the bios chip is a 8mb chip(GD25Q80CSIG) but all over the internet I only find 16mb bios file..what the heck!!?? motherboard number: NM-C451

        The chip is 8M-bit ,8 mega bits . 8M-bit = 1MB .You have found the wrong chip. A 16MB bios will be a 128M-bit chip. 128M-bit / 16M-byte

          Is the 16mb chip smaller than the 8mb? I can't find it..

            In physical size no. Its a WSON8 chip. Don`t try and use a SOP8 clip to read it . I suggest you do some reading first before you do anything else https://www.badcaps.net/forum/showthread.php?t=103526

                GL4A5/GL5A5 NM-C741 Schematic
                by cicos
                Does anyone have a LENOVO schematic
                MB : 20U7-0002GE
                MAIN : GL4A5/GL5A5 NM-C741 Rev:1.0
                CPU : AMD RYZEN 5

                There is a difference in the 20V power supply from the scheme posted here.

                Problem

                This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                Schematic or datasheet for Plasma TV buffer chip
                by Yanleb
                Hi all,

                I'm interested in understanding how a buffer board chip is working. I know there's about 90 outputs per chip to the plasma panel, but I'm more interested to know about the input pins. I guess that some of them are address pins, but I want to know more.

                So far I've found nothing at all. I haven't found any datasheet about the various buffer chips, and I haven't found any schematic for the buffer board using them (Y Buffer Board in Samsung's terminology).

                Any information will make me happy. It can be from any buffer chip or plasma TV manufacturer....

                LG 42PC3 buffer output doesn't follow YSUS
                by legg
                LG42PC3D -UD originally with green lamp but no display or audio.
                Owner says was working, then went 'pop'.
                All 5V caps bulging. replaced.
                All PSU output voltages within spec but -Vy is low on YSUS.
                One of three parallel fets between SUS_OUT and SUS_DN is zenering,
                eventually shorts DG. Replaced all 3 - -Vy now OK.

                Y scan buffer test point does not follow YSUS output below -50V

                Note: This unit seems to expect YSUS output to park at -Vy in between
                drive signal pattern periods. A replacement drive signal board confirms this....
