    Vizio M470SV

    Ok guys and gals. I have this TV, Vizio M470SV. It was working fine and then all of a sudden started becoming VERY slow to commands and then even shutting off at times. I have reset and factory reset (cleared memory) and still same issues. I was thinking it maybe the eeprom or firmware but not sure. The TV is now pretty much unusable at this time. Any ideas or suggestions?

      Re: Vizio M470SV

      Since Vizio states these TVs update only over the internet, is there a way to replace the eeprom and jtag the board to write the firmware or flash it using the USB port?

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

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

          My maintenance cartridge tank unfortunately is "full". Can anybody help me to reset it? I have the dump file read from the 4g16 chip....

          Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
          by Tynan Dill
          I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

          Upon bringing it home and plugging it up, it showed a standby light.

          I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

          The screen seems to blackout and stay black, but with a flashlight I can see the display.

          With my Playstation 4 connected via HDMI, and running a game I can hear sound.

          Assuming...

          Vizio a320-a0 eeprom
          by RDC55
          Hi everyone,

          I was trying to repair this Vizio 32 inch and have isolated it to the EEPROM. The symptoms are it does not respond to the power button and so no backlights or any indication that the button was even pressed. Applying freeze spray to the EEPROM while the set is unplugged, and then plugging it in and all is well.

          Now I know I can buy pre-programmed EEPROMS for $15.00 or so, but I wanted to do this myself. So, the original EEPROM is Winbond 25Q64FSIG. I ordered this but received a 25Q64JSIG, which has slightly different timing characteristics. Well, being hopeful...

          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:

          https://cdn.badcaps-static.com/pdfs/...c6e42b20d3.pdf 2

          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...
