Bluray won't show after unbrick

Hey guys,

i unbricked my ps3 slim and now there is no bluray icon anymore.
the drive worked prior to the brick so it would be a funny coincidence.
i tried remarrying and it looks like it passes but then just shuts down and nothing changed.
It could be that i damaged some wires but i don'T think i did is there anything i could try to make sure whats the problem?

Thanks
