Hi Bizeek,
I have exactly the same problem you had, all the exact same symptoms.
I tried all the resets as you did to no avail also.
I have spent an enormous amount of time on this problem, and have tried everything, not LED backlight, etc, etc.
What was the final resolution to your problem?
I am simply dying to know........
i would also gladly welcome, with open arms, any thoughts that anyone might have on this subject.
I thank anyone who takes the time to post and help others.
Untold suffering and anguish has been averted thanks to people helping strangers out.....
