The controls for my P2570 monitor never functioned correctly but the picture was fine – for the first 6 months. Then the monitor would just go white. After taking it to an authorized repair shop both the technician and I have been frustrated in trying to get a repair part or even the status for one from Samsung. The Samsung ‘customer service’ line said the same thing: they could not provide a status or confirm that the needed part would be sent. After suggesting this was not an answer and requesting it be escalated to their supervisor I was advised – ‘No! You will just have to wait until the system delivers the part.’
I am extremely disappointed in Samsung – their monitor and perhaps more significantly their lack of customer service. For me the Samsung brand now means: do not buy!
