Hey, i have a switch here, i completly checked the mainboard ,

Pin 6 3.3 V
Pin 9 VB 5 V
BQ Chip works well too and the battery charges as well,fuse is okay, filters are okay

But the backlight is not turning on, finding no mistakes, so i used a payload (attached a pic) and now the backlight turns on and i have the options_
Launch firmeware

I'm no 100% sure but it sounds like you need to add custom firmware to the SD card (atmosphere for instance) and then select launch firmware from the menu you are seeing.
If it boots into this new firmware then it suggests the software on the nintendo memory module (EMMC) is corrupt/unseated/dry or broken joint on the IC.
The EMMC is paired with the main SOC so you can't move them between switches unless you take the SOC and EMMC

So, i put the SD Card inside and load a payload and atmos was starting and im in the menu, so, what i understand now, that the normal firmware is not working just with atmos i can play or?

in consol settings : 6.2 logic system / AMS 0.11.S

There are a couple of options:

1. try to backup the EMMC contents. There are guides on this forum on how to do this and then get a new EMMC and upload everything onto the new one and see if that fixes the issue.
2. Send it to Nintendo for repair. It will probably cost around 60 euro to have it fixed. I've used the Nintendo repair service about 4 times now and it always costs £54 for a repair so far. The downside will be the Switch will be patched when its returned.

There might be other options that I haven't mentioned but I'm sure someone on here will fill you in.
