White Screen With Coloured Lines
I recently got a Macbook Air A1237 from a customer with broken hinges, lcd cable worn (where hinges damaged) and when booting, it shows a white screen, then coloured lines fade in. I have used a micro DVI cable to output the video, so it seems the GPU is fine.
I have tried a new LCD, LCD cable but it still has the same issue (frustrating). The LCD connector looks fine and I have also tried PRAM and SMC reset to no avail.
I have noticed some burned components and traces on the back of the board (I will try to attach a picture) which could be the cause, but I am unsure of this. I have replaced fuses and connectors on other models before, but I am not sure which ones these would be, and if it would be the cause of the issue. All three of the components look burned, but the middle has not got a readout, and seems the worst.
(sorry for bad image, I have circled burnt components
I now regret getting this machine in (PITA to work on), and I am hoping to resolve this for my very patient customer. Any help appreciated :)
Is this a good question?
