My bottom LCD will turn on then off immediately same with the blue led

Hi, I have had my Nintendo DSi XL for maybe 6 - 5 years I think, and I love it so much, but I had charged it one night and the next morning it wouldn’t turn on. The bottom LCD would just flash on then off, and the blue led will go on then off. It is pretty damaged so could be something with the top LCD ribbon cable but I don’t know how to fix it.
