Re: Vizio TV firmware reverse engineering
Have you read my post? If I replace flash IC from m65-c1 to d50, d50 turns on with m65-c1 settings and works until power cycle. So I'm sure settings stored in it....

Vizio TV firmware reverse engineering
Hello!
I'm trying to install mainboard from d50u-d1 into m65-c1 TV. They are the same, deference in panel settings only.
I got access to factory menu but it doesn't allow to change panel settings.
I have tried to replace MX25L3206E Flash chip from bad m65-c1 board to new d50u-d1, the TV turns on and works until power cycle. Then TV writes default d50u-d1 setting in flash chip and it doesn't work anymore.
I need help with analyzing file dumps to find where are panel settings to modify them in original file.
here are 3 files:
2 original... -

Vizio service menu code
There are a lot of different codes on internet but they doesn't work for all modern Vizio TVs.
Here is tested code to enter service menu (factory menu), tested by me on D-series and P-series:
MENU-1-9-9-9-Return.
(Retun is a button with round arrow on remote)
Overall the menu is useless because it doesn't allow to change panel and LVDS settings...
If anybody knows any other codes for Vizio, post it here, please.
By the way, Philips TVs uses the same main boards with same service menu access code...... -

I don’t.
As I wrote, it may be the problem in light sensor. But I don’t have any to check....Last edited by ARGO; 11-03-2018, 11:58 PM.Leave a comment:
