Is there any way to reset a parameter wrongly placed and saved in the service menu of TV SONY...

Hello all.
I'm new to the forum and seek to resolve a mistake I made. I changed a setting in the service menu of my TV SONY KDL-NX711. When I turned on the TV again, no picture, no sound. The green LED turns on, but nothing happens. My TV died permanently, or is there a way to reset the service menu? I emphasize that there is no menu visible on the screen. It would be a blind reset. I thank anyone who can help me.

From SONY KDL-NX717 Service Manual:

2-4. RESETTING THE TV TO FACTORY CONDITION
Use the following instructions to restore the User Adjustments
and Channel Memory settings to the preset factory conditions.
1. While holding down the [up arrow]on the Remote Commander,
press the POWER button on the TV Switch Unit of the set.

The set restarts and displays the Initial Setup screen. This
may take several minutes.

2-4-1. RESETTING THE TV TO FACTORY CONDITION USING
SERVICE MODE
1. TV must be in Standby Mode. (POWER off).
2. Press the following buttons on the Remote Commander
within a second of each other:
[DISPLAY]> Channel [5]> Volume [+]> [POWER] .
3. If necessary, press [JUMP] or [OPTIONS] to go to DIGITAL
mode.
4. Press 8 .
“SERVICE” changes to green RST.
5. Press MUTING.
RST executes the command and displays EXE.
6. Press 0 .
EXE-RST displays green, then red indicating the TV is
writing the data.
7. When the process is complete the green SERVICE text
displays and the LED display as shown below:
TIMER Standby POWER
8. Cycle AC Power (Unplug and Plug AC Cord from the
AC Outlet).
9. The set restarts and displays the Initial Setup screen.
This may take several minutes

Your model is not listed, so choose the closest model, mostly enter service mode etc. is the same.
You can only download 2 SM pdf free, each day!

thanks for your help, but I already tried this mode. I have a problem to do this, there is no image on the screen. I did the procedure indicated without seeing anything. So I think that is not a viable way to solve the problem. I'm starting to think unintentionally changed some parameter irreversible. In the service menu there is a warning to not make changes to the item "location" or risk having to replace Buth BOARD. Keep trying the alternatives that appear, but so far everything has gone wrong.

Changes made in sm of a sony tv are not perment unless saved by 2 key presses for got what they are 9 and mute or something like that. The tv will rember settings untill the set is unpluged. Then it will revert back to what ever setting were there before changes were made. I suspect that if unpluging does not restore it that its a coincadince.

Thanks again for the tips. I've tried every way possible, but the TV just starts, the green LED lights up, but does not show any picture or sound. Assuming that really could have been saved some improper configuration, is there anything I can do?
