    Schematic or datasheet for Plasma TV buffer chip

    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. I don't really care. All I want is to learn something that will help me troubleshoot plasma TVs in general.

    I already know how to pinpoint a shorted buffer chip. Again I'm searching for technical data about buffer chips.

    Thanks.

      Thank you Biruslapio. I've never seen this chip. Usually what I see are Renesas and Panasonic chips. I was not aware that TI was making them also.

      For sure it will help me to learn. Thanks again.

        ST also has very useful datasheets, I had no luck finding any Panasonic or Renesas.

            Thank you Biruslapio. The ST datasheets are a real gold mine of information. This is strange I never seen a ST chip in a plasma TV.

            And thank you Iotas. The Panasonic chip pinout will be useful. This is very very stange. The datasheet of the Panasonic AN16021 is an exact copy of the SN755870KPZT that Biruslapio sent.

              Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
              by acedogblast
              This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

              There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

              Buffer data does not match SPI chip!
              by macmino
              Hi all, after several attempt, I finally got a working CH341 Pro working USB device. Now I'm able to read dump the BIOS

              When I verify the image (800G6_EC_RCunlocked.BIN found on this forum) I receive "Buffer data does not match SPI chip!". I tried different programmer but the message is the same. Anyway, I removed the password but I see at the boot the HP Message:

              "HP Endpoint Security Controller Problem"


              When I hit OK, the boot continues and I'm able to use the computer. Did. the SPI chip not match error caused the error?

              by H34TO
              Recently I've gotten into EC flashing due to my broken laptop(s) and started frantically searching methods for flashing the IT5571E-128 chip on the cheap(due to me beaing a student and not having a job) and noticed that ITE newer chips can be flashed via ISP (In-System Programming) either via SMBus or the KBC (EPP - Enhanced Parallel Port) interface. While these can be achieved with programmers like SVOD4/3 or the RT809H/F those options are WAYYY out of my budget so I was horrified. But recently I stumbled uppon some programmers on aliexpress that claim they can program a variety of ITE chips...
