screen wont turn on, still hear alarm, wont connect to itunes

ok little backstory for clarification: basically about a year by now, i dropped the ipad on my basement floor, wasnt a far drop at all, but when it dropped, it developed dots on the right side i believe, the dots were lighter than the rest of the screen, but the ipad still worked good, wasnt much wrong w it. this happened twice, first time, the dots faded within about a month, then happened a second time and the dots stayed since. about a few months back (march), it just randomly wouldnt turn on (the screen at least), i gave up then but im coming back to it now, i still hear my alarm, but at a low volume. when i try to turn it up, the alarm just turns off. and it will not connect to itunes, it doesnt even register to my computer in GENERAL. i feel like it charges but im really not sure because i was on silent mode before it stopped working so i cant hear the charging sound. do it need a repair or is there something i can do on my own?
