I have a Sony Bravia KDL-40V4100. Whether I select custom, standard, or cinema picture mode it will revert to vivid after about five minutes. I cannot watch a DvD without hitting the picture button every few minutes to go back to custom. It's driving me crazy. Has anyone else experienced this problem. I have turned the light sensor off but this makes no differnce. It was a display model at Sears for about 8 months before I purchased it.
Thanks
