I have a 2007 MBP3,1 A1226 15.4" LED on OSX Lion, Snow and Windows 7. While watching a HD movie on an Epson projector the picture went blank and the laptop was overheated. Pressing F7 did not recover the picture internally or externally, so I forced shutdown until the laptop was cooled down. Later when I turned it on the internal display was OK for a while and then it started flashing until it died. Connecting an external monitor was the only working solution. I tried resetting PRAM/NVRAM no luck. The test with the torch behind the apple logo shows no faint image. External monitors work, but since the internal display died: a. there is no monitor detection so I have to select a predefined resolution b. it works only with DVI-I cable, and not with DVI-D anymore. Can you figure out what needs to be replaced: 1. LCD panel 2. LED driver board 3. Logic board 4. Repair the graphics card Any suggestions?
