Hi & thanks for the tips. Update, today took apart and cleaned connectors with isopropyl alcohol & can now see screen image but very faint/ greyed-out. Suspect the LCD back-light is the problem. I DO know a micro-solderer but expect cost of repair may be uneconomic...unless he'll do it for a case of beer! Any other ideas on the back-light problem I can look for myself? Failing that anyone know of a good source for new logic boards? Cheers...
Hi, I've have this exact same issue: Screen replaced....everything boots up, iTunes sees it, camera clicks, battery is charging etc.....but black screen? When I reset using home/ sleep button combination I get the 'Apple Logo' very biefly, for about half a second & then goes black again? I've tried a restore in DFU mode & other screens...same. Any ideas please?
Be very careful under the right hand side of the board with any tool...there are some small resistors near the headphone-jack that can easily be knocked off.
