Im sorry to hear that.
I wish I had better news for you on this , I really do, but this one needs repair service.
Due to its age, (and its about at its lifes end), it would need a specific IC the EPROM IC has failed.
You can have this repaired by bringing it to Best Buy or Sears, but that costs about $ 60.00 US. If I were you I would simply replace this one because the new ones are cheaper than that one was six years ago. And the new ones have way more awesome features and do a lot more for less.
If you do want it fixed instead of replacing this one please let me knwo and I will direct you to the best place online ven for that;-)
But other parts will begin to fail soon after you repair this, so its really not worth the cost;-(
In any case, I will stick with you until this is complete.
Please rate my service kindly.
Also it is the only way I am credited for my time and expertise with you.
