Good morning all, I tried powering my P4 this morning just to find out that it isn't displaying on my screen. Tho, I switched it off automatically from d socket last night without shutting it down properly. It is just a black screen whereas the P4 is working properly, I've changed the HDMI it still the same thing. I went to the repairer he said I should change d display IC. Please anyone with an idea of what could be the problem?
