Fix Vizio TV E320/E371VL, E370/E371VL, E420 stuck on standby (EEPROM Dump)
It seem like a few popular Vizio HD TV set suffer from a similar EEPROM corruption as the Sony Playstation 3D TV. Turn out that many of them stop working after a while for no apparent reason. I do not have this particular TV set so this article will be much lighter in pictures than my regular article but from what I have read, the TV stop powering on and stay with the organge Stand-By light. It will sometime boot after numerous try but will stop working again after a while, sometime appearing to turn on but freezing at the white Vizio logo screen. And as when I was looking to repair my Sony Playstation 3D TV, I could find many people selling the replacement chip but nobody seemed to be sharing the chip data for home repair. These kind of situation frustrate me a lot as I believe that this kind of information should be freely available. So I decided to remedy this by buying a replacement chip and dumping it's content.
Here are the EEPROM Dump (the EEPROM you need is 25Q64):

The EEPROM location on the TV circuit board is U18.
Now, people (with the proper equipment) should be able to repair their Visio TV without sending it to a repair man or without buying a pre-programmed chips online.Twitter

I do not have this TV so it would be hard for me to verify but the best thing I can tell you would be to look for a chip that is the same size and same number of pin (soic8) on the board and try to read the top of the chip. Find the one that is the same part number or one that is similar and check if the part number is for an eeprom.
I use a GQ-4X universal programmer. As for adapter, I got a clip on eBay, you can see it in my article on fixing the Sony 3D TV, just look for ''soic8 programming clip'' on ebay and you'll find a bunch of cheap one.
Good luck!
I can't confirm 100% as I do not have this tv but I would think it is compatible since it's part of the same series (e420). Also, it seem to be compatible with other model like the e320, e370 etc... So I would think it would be compatible but again, no way to know for sure without trying.
Let me know if you do try!
Thank you so much for the quick response, I have another question I hope you dont mind, I am new to eeprom dumps but i have been doing soldering for a while, I saw your page has some interesting information, but I would like to know what device you use to do the dumps and flash as I wanna buy me one, also as I was looking on ebay I saw adaptors that come with the machines and I am confused of how that works, would you consider doing a little tutorial on that with information such as eeprom sizes and flashers
Thank you so much
Hi Gabriel,

Thank you
Thank you for sharing those files. I downloaded the data for E420VO, copied to a new EEPROM, installed it and It worked!.
Once again, thanks for sharing!
Awesome, I'm glad it helped you out! That's exactly why I made this website in the first place so I always get happy hearing that it helped someone.
Thank you for the dump to the Vizio TV
we have in Ukraine there is no technical information about Vizio
here is your firmware to this TV really helped-tv earned)
