Nintendo switch v1 no boot after logo

I’ve been trying to repair this console for a while with low success. I’m at a point where it powers on and shows logo but nothing further. I tried running hekate bootloader but crashed with distorted display. I’m very suspicious of the ram. It once had BSOD but got that fixed by reballing both the ram and apu soc. Has anyone experienced this and what would be your next move.
