I've got a 360 JTAG that doesn't get much use but when it does, is generally fine. Now whenever I power it on the power light comes up but no ring of light, and nothing on the screen. No audio either. It's a Falcon motherboard and has had the 12V Fan mod done on it (I purchased it as is). I've done a bit of searching and the results I'm getting is it could need new thermal paste on the heatsinks? Is this also known as the X-Clamp fix?
