Having Display issues, works with external/ no camera detected
am a new member to this community and I'm already getting a headache from my macbook. So my mac has been working flawlessly for the past 2 weeks or so ( Macbook A1342 Late 2009 w/ OSX Lion). I have SMCfan control and istat pro to keep an eye on temps and to stay ahead of the heatsoak game. I did a "deep discharge" of the battery then waited a few hours to plug it back in and when i did and let it charge up, I then proceded to turn it on and do some light surfing if any, mostly idle though. While i was doing that i noticed that the temps were starting to soar up to 80-94 degrees C. I turned up the fans to full throttle to get it cool and it cooled it down to say 60-70's. Okay, now afterwards, I rebooted the mac and then it started giving me more issues as in no display, but I do hear the chime and it seems to boot as normal just no display. I plugged in my mini dvi to hdmi connector to a tv and BOOM, the screen popped right up on the TV like it was supposed to; at this time i became very confused. Now i know that the macbook camera and LVDS cord are connected together so while it was still connected to the external display i attempted to turn on the camera with Facetime and it said camera was not detected!!?? So I'm not sure what the issue is, I am currently deployed to an undisclosed location in SW Asia for a while so I am unable to go to any repair store. I consider myself very technically inclined so repairing this would not be an issue within reason of course. Is it the logic board, if it were it wouldn't start up right?? Is it the LVDS cable, I popped off the back of the mac and looked at the connector and it seems fine, i unplugged it then plugged it back in and no change. When it was connected to the external display, it seemed to be running flawlessly...I was unable to see any problems on the screen, but like i said nothing came up on the mac screen and no camera was found, no green light came on either. Please help...I really need this thing back up and running, and I apologize for the long first post.
MacBook (13-inch Late 2009), Mac OS X (10.7.4)
Still working on this matter...no luck yet.
First and foremost, thanks for getting back w/ me on this matter. I have done the SMC and PRAM reset several times with no luck. I've re-seated the LVDS cable and checked for any lose or damaged wires, nothing. I've also shined a flashlight up to the screen and i saw absolutely nothing...so I'm not getting anything at all on the screen. It did previously have h20 damage and was repaired over a month ago from a reputable repair facility. I have already ordered a new LVDS cable and a new LCD display and I also have another 2.26 logic board coming in later in the next few weeks. I plan on starting with replacing the cable first, then try it, if nothing then I will move onto the display and if nothing from there guess i will just replace logic board. Do you think it could have anything to do with the Nvidia grapics chip? I've read online about previous mac's that reflow issues, anyone ever heard of these symptoms from a GPU issue??
