Ok so I went under my bed I forgot I had a Xbox 360 under there and It still works its just that the DVD drive it is plugged in and everything and I checked to see if its plugged in and the middle light on the rft board still flashes any ideas? To fix this? I got like 5 other motherboard so getting parts will not be a problem?
1st of all the reason it is blinking is due to the fact its not in the right postiion. meaning opened all the way or closed all the way. The only other thing that can cause this is someone tried to flash the dvd drive and didnt do it properly. being that i see you mentioned it is a jasper. I am thinking its a lite-on dvd drive.
first thing i would try is like everyone else suggested is to take and replace the sata cable or the power cable . If that doesnt work then i would take it apart and clean it and make sure the try is working properly. So many people try to manually open the dvd drives and mess up the gray tray and causes it not to close all the way . so look everything over really good.
If its a bad flash it could be bricked. and you have to unbrick it which is very easy to do. I have purchased many consoles with this issue and usually a pretty simple fix.
