Had this keyboard since I was 15 I'm now 27 lol. But it cost a lot of money back then and I really want it fixed. At first like 4 keys wouldn't work so I went on YouTube on how to fix the problem, took it apart took all the keys off cleaned it all like it said in the video, put all the keys back on and now, instead of just 4 keys not working around 45 don't work. I don't know what to do :(
