Nintendo switch doesn't boot in cfw/ofw

Hi, I changed digitizer for my switch 2017, before gluying back the screen to the switch I tested it powering it on and worked fine, after I glued I tryed again and still working fine on ofw. After that I went for a thermal paste change, even the one under the cpu shield, everything okay also because I am familiar with switch and hardware, mouted everything I turned on the switch but just black screen. Going into hekate works but even cfw does the exactly same thing. Please help me!!
