Hello to all ! * I bought a macbook white unibody A1342 2010 on ebay and I state , the seller had reported this problem. Since I'm delighted for years in the assembly pc / mac and I also have a discrete experience on the hardware of the notebook I decided to buy it with the intent obviously thinking to fix it , given the description of the problem in question , to get by the worse with the replacement of the monitor. * In fact, this happens to me : * I state the notebook works perfectly but the screen stays on but white and rye monitor works only via the displayport vga adapter when the system is running. I disassembled the laptop to the last piece and apparently seems in order. Lvds cable connections appear to be correct . I then ordered a new monitor Lg always on ebay and in the meantime removing the theoretically fault I noticed a note on the back of a pen with the November date , 2013. I got the new monitor connected immediately but unfortunately same problem. * Probably those who sold it to me had already tried unsuccessfully to replace the monitor ( villain ) ! * By instinct I would say that could be the lvds cable but before spending more money I would like to be sure. * Can you advise ? Have you had similar experiences? * It is not excluded that in case of a problem on the logic board but it would seem strange because the video signal from the display port out properly. * Thanks in advance for your advice !
