dark screen on a toshiba...i replaced it and STILL dark. can it be more than the screen?

[berbes]

i had a client bring in a toshiba c55-c5241 satellite with a dark screen. i shine a light into it, and i can see everything, so, i'm thinking it's a backlight and just replace the screen. i do, and sure enough it ALSO is dark, just like the original.

i've never had this happen before. did i get a bad screen or what else could be the problem?

thank you!

Im not knowledgeable in replacing laptop screens but did come across this. If it helps in anyway, great.

Could be the screen wires. Was the whole screen replaced along with wires?

Not sure if that laptop is near enough identical to help, ifixit only has a guide for 5240 model. Was going by this https://laptoping.com/specs/product/toshiba-satellite-c55-c5240/

thank you for the great guide! i guess if the cable is bad, it also mimics a bad screen. i just never had a dark screen repair that turned out to be the cable before.
