This is a common problem on this model. I've never been able to confirm my suspicions (haven't had a second one to work on yet) but I believe it to be the 8 pin buck converter IC on the power board failing. You can replace it, I forget the part number but it is written on the device. Post a picture of your power board if you need help locating it.

It's probably this IC you should replace.
If replacing this fixes the issue PLEASE report this back so we know, this problem is so common and it has not yet been determined if this is the actual fix.
