I apologize in advance because I posted a similar thread recently but was not really helped in any way.
My Xbox 360 is a refurbished, slim, 250gb. I experienced a red dot a week ago(no ring, only the center dot) and it froze. No error message, nothing. Now, every time I turn it on the screen will go black a couple seconds into the splash screen. The Xbox remains powered on but my controller never syncs...well the screen is black anyways so what could I do...
I've tried removing the hdd(system will power on with it removed, but the screen remains black), unhooking all of the power supply cords, plugged the power brick into a power strip as well as my wall outlet. It is in a very well ventilated area.
I haven't seen the red dot since the problems started. Sometimes my Xbox will load to the dashboard and work but if I turn it off and back on, it will freeze at the splash screen. I think it works about once out of every 40 times I turn it on.
The flashing lights wizard will not help me, as only the center dot was red. I have no warranty. I've considered buying a 4gb model and transferring my 250hdd to it(if that would work).
