Hi, I have my friend's 360 which is suffering from 3ROD. I opened it up and found that there was only 1 x-clamp as he has sent it before twice to shop for repair. Previous malfunctions was also 3ROD. This is my 1st time with 360 therefore I didnt try the x-clamp fix instead sent it to shop. 1 week later the guy from the shop said 'they DONT want to repair it because some parts were missing'. So I took it back and wanted to try the x-clamp fix and I noticed the x-clamp was removed and replaced with screws n nylon washers for both the GPU n CPU heatsinks and fresh thermal paste " its not like they DONT want to repair it, I'm guessing they CANT repair it...

I tried the x-clamp fix but to no avail. Any suggestions? I dont even know what type of error this 360 has, nothing came on the screen where switched on.
