    Panasonic Vierra frequent EEPROM corruption

    Hello i had some trouble with a Panasonic LCD TV a few months back and after a lot of trying i figured out that doing a factory hard reset cured the problem. The TV originally wouldn't come on and kept flashing it's red LED.

    PANASONIC TX-LR32C3

    Panel: VVX32H100G00
    PSU: TNPA5361AA4P
    Main: TNP8EA112

    I used the following reset sequence:

    Turn the TV off.
    Hold the F button and Vol- button on the side. Then hold the power button (also on the side).
    Wait for 3-10 seconds for the backlight to come on.

    The TV has worked for perhaps a couple of months since doing the reset but now the problem is back. Would replacing the two EEPROM ic's that this set has be a sensible step to take? I have various programmers that im sure support these chip models.

    IC's are: 24С16, 24С32

    I'm not 100% sure why there are two or what each ones purpose is but i'm guessing that when you tell the TV to factory reset, one or more of these chips has their data cleaned up/settings wiped? Would it be logical to think that maybe one of these has failed causing regular corruption?

    or any other ideas? Help much appreciated.

    Thanks,
    James.

      It's not going to hurt replacing them and they aren't expensive.
      They have a finite lifespan, so it's possible it's failing or the data is corrupt.

          93C46 and 93C56 EEPROM
          by SidneyCanadas
          I tore apart my instrument cluster for my 2008 Toyota Corolla made in 2007 in Cambridge, Ontario, Canada and pcb location: IC6=EEPROM is a surface mounted device with part # of 93C46W7, some claim the EEPROM out of a Camry part # 93C56 will allow odometer to roll over 299 999 KM or miles. The data sheet for both is below:

          Anyone know if the Camry one will work on my Corolla?. And which EEPROM reader/writers do you all recommend I purchase that will allow me to read the old values of the old...

          Panasonic TC-P55ST50 8 blinks then no blinks
          by Andre Gilbert
          Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
          Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.

          Pioneer DEX-P99rs "No EEProm " diagnostic code.
          by dmccul2698
          Hello, My head unit developed strange behaviors so I ran the built-in diagnostic package which returned "No EEProm". The service manual says there is no EEProm connected. I approached Pioneer and they said to swap out the DSP board. All said and good but the DSP board is $860 USD. I am hoping someone can help me

          1). Understand the schematic and check the connections between the EEProm and DSP
          2). Check the functionality of the EEProm

          I don't know if this is the unit's problem but it's a place to start.

          I have little to no electronic experience...

          Problem with PANASONIC CF53 laptop after changing BIOS settings
          by AquaMan Ua
          Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in...

          Damaged EEPROM on TV Vizio E320-A0
          by edgarmg15
          Hi everyone

          I´m trying to repair a TV Vizio E320-A0 that I found in the street

          The symptoms are it doesn't respond with remote or buttons, the LED indicator is always off and also there is no image on the TV.

          The power supply board works fine (I probed the terminals with my multimeter) but in the main board the EEPROM doesn't works correctly because the voltage on the pins doesn't match with the parameters of the datasheet.

          So, I´m going to replace the EEPROM with a new one, but the problem is that my programmer (CH341a)...
