I am having my Samsung HCL4715W RPTV ISFd sometime soon I am hoping....... when my replacement screen cover shows up. It didn't last time. I think I may have upset the guy when I asked him to fix it and then again when or if the new screen shows up but thats not what I'm posting a thread about. I have no dout that he is an expert and he certainly has done great in the past but I want to be sure he isn't leaving something out because he may not be getting payed much by ____ and probobly has little free time. He is friendly and explains things well and I enjoy having him over, but I guess to often is not practical. Now the questions. 1) Is it normal for there to be visible changes in brightness mostly influenced by the position you view the set? For example standing there may be faint lines (about 3 or 4) at the bottom. When sitting, they appear in the middle. When sitting on the floor they appear at the top. When panning up and down there is a constant array of brighter horizontal lines somewhat similar to one of those animation pictures that change when you tilt them up or down. It looks almost like the texture in the screen. The changes and number of lines are not perfectly seperated and non uniform when comparing a top view to a lower view. Is that normal? I'ts been cleaned before. 2) Why is it when there is very dramatic black on white images on the right or left side it causes shadows or "halos" ? I can almost intirely eliminate this rare problem by setting the contrast to zero. I would even notice it unless I was watching for it. Can it be improved so that I could turn up the contrast? All of the guns seem ok as there is an even brightness with a white screen (except for issue in question # 1). Is that just normal also? 3) After my user convergance setup it looks great except a faint transparent outline to the right of everything. Could that be fixed in the service menu or is that a focus issue? My final note: I have the service manual coming in the mail soon. I also have a screen cover orderd and a skilled pro to fix it thanks to the service agreement I bought. I have a website that I update it pretty often. Don't everybody rush to answer at once now. We want to save bandwidth for others.
