Re: 9500 Storm Black Screen
I assume that you purchased it used?
My suggestion, given the problems you are experiencing, is to return it and get your money back. If it was new, return it for a replacement.
The issues you describe could be caused by many things. Your problems are indicative of a device which has been caused by dropping or water, even though there is no water damage indication. Even a little moisture, say from a steamy shower area or sweat, can cause some of the problems you have.
Also, the motherboard could be damaged, the screen damaged or has a short in the connection. Almost impossible to pinpoint with taking it apart.
If you insist on keeping it, I would find an authorized repair center and let them have a go. However, my guess is that it will cost more to fix than to replace.
What do you consider a suitable solution?
