Vizio D50-F1 - Can't update Software / Firmware

[jason123]

Wondering if any of you have seen this before. I got this TV with lower half of the screen dim. Fixed the LED backlight issue - smooth

I noticed that the System update lists current firmware is V1.0.6 and is able to find on the Vizio server 2.60.23-1... it downloads fully.. but instead of restarting, it just goes back to the previous screen "NO SIGNAL - HDMI1"

I got the code and followed the update via flash drive - and it does exactly the same thing. Firmware is copied by the TV 100%, and then nothing - instead of restarting, it just goes back to the previous screen "NO SIGNAL - HDMI1"

When I check the System Info, still lists V1.0.6 as current firmware (so process never completes)

Got with Vizio Tech support - had me reset the TV (Back to Factory Reset) and the TV is doing exactly the same as above. They suggested I schedule service!

Any thoughts on what can be wrong? I recall years ago a TV had "Allow FW update set to Disabled" in the service menu. Can't seem to get there.

Also, I couldn't find earlier firmware for this TV. I'm thinking jumping from 1.0.6 to 2.60.23-1 maybe a big jump and if I can gradually get there, it might work.

Help is always appreciated! Thank you

If anyone has a way to access service menu, or has service manual, that would greatly help! menu 1 9 9 9 and others simply don't get you anywhere

Try to press "last" or "return" button after digits

Only methods 3-6 are applicable as there is no "Ch+" or "Ch-" on this TV.
Return (Enter / OK) or Back don't seem to make a difference. I don't see any special menus pop up.

Does anyone know where this firmware is stored? is it in the nand flash? This board has an ARM processor and a Kingston EMMC04G-M627-M06U drive. Was curious if anyone had any luck programming this firmware with development tools? or if even worth it?

It has no NAND, the firmware is in EMMC (Kingston EMMC04G-M627-M06U).
