Listen very carefully I’m going to write this one time so this thread can die and get buried.
If your screen is broke and it was your fault you need to try to fix it yourself because your warranty is void. If the screen broke on its own and is defective you need to call Sandisk Tech support and discuss an RMA under warranty. PERIOD
As for your EQ. You cant access it via your computer because thats not how it was designed. It is completely self contained in the unit. Thats it.
Also please note while SMS Speak is pretty much acceptable some places this is not one of them. We are fellow users who are just willing to be helpful to others who have players, and not everyone here speaks english as a first language, so using those abbreviations is just asking us not to help you.
Use plain english so everyone here can read it and understand it. Otherwise you probably wont get any more help.
