Very bad news. My Lumia 800 developer device suddenly has a black screen (no scratch or drop to the toilet). Then I take it to local Nokia Care office for checking and the conclusion is my screen is unfunctional (when the service staff replace with another screen it works). But my device is not in the warranty so they will charge me more than 300 SGD to replace a new screen (I received the device from Nokia through DHL this January). So what should I do now? Send the device back to Nokia developer team for repair? Any suggestion is appreciated. Thanks.
