[QUOTE="bsrngeorge, post: 1346669, member: 230717"] Ok I made a big boo boo while working on my iMac. I have had it open several times in the past with no problems but this time I pulled the larger ribbon cable in the middle, right above the video card, and the bracket broke off and pulled away from the pins. I Think I managed to push the bracket back onto the pins, it looks good and all pins are aligned into their respective holes. I put it all back together and when I power up I get the gong right away but no video whatsoever and the fans are running full speed. My sync cable is also kind of worn but I don't think that is the problem, I should still have some video if the sync cable is bad or not hooked up. My original thought was that the LCD temp sensor is bad, but of course that thing I did with the pin bracket on the logic board has me scared as well. Since I get a boot gong I assume the computer is working but I do not have cables to hook up an external monitor, nor do I have any sharing set up to be able to see it on my network so I don't know for a fact that it has booted and is fully working. Does anyone have any idea on how to bypass the lcd temp sensor so I can check that component first? If it IS bad I will know to replace just it, and my sync cable while I am in it again. I just cannot believe it would be the lcd cable, the fans should not run full speed if that cable was plugged in wrong, or not plugged in at all. Thanks, George [/QUOTE]
