I brought MBP 13 laptop in OCT 2011, it was working fine. Two days before when i started my mac after booting i saw flickering on display. This has happened for the first time. So i immediately carried out shut down operation. After that i tried to restart my mac but display went on to show blank (black) screen. Then i immediately took MBP to Apple authorized RGL service centre they charged around $50 for diagnosis which i paid in advance as my MBP is out of warranty. After diagnosis service guy told me that display is ok but power supply from Logic board to display is affected and i need it to replace logic board which will cost me around $600. This it totally unacceptable. This service guy has no answer to my question, Why this has happened? He only went on to say again and again that i should have taken extended warranty cover. We get this specific complaints about this product regularly. Even i noticed, in last two days i saw 3 -5 person with the same problem with their MBP 13. That means its a manufacturing defect. I even searched on the internet regarding MBP 13 logic board problem and i noticed there are many people having same problem with their MBP13. What should i do now? Does it have any alternate solution. Or Should i file a case in consumer court?
