All, First post and I apologize that I'm already asking for help. I've been reading this forum on and off for a while and I've looked to see if anyone has had this problem but have not seen it. I've had my Samsung DLP for about 18 months and just recently, I noticed a small rectangular black box about 1" long by a 1/4" tall on the upper left hand corner of the screen. It comes and goes and I've only noticed it while viewing recorded stuff off my Time Warner DVR. I'm not sure if it appears during regular TV watching or not but I haven't noticed it yet. Has anyone ever experienced this? Does anyone know what it is? Thanks for your help.
