Question about Hitachi 50V500 50 in. HD-Ready LCD Television
Help! Not only does my tv take a long time to warm up, but while watching tv programs, there are pale yellow splotches located in various places all over the screen! Hope you can help! Similar problem. But I have a blue color that looks like it is 'bleeding' from the the top of the screen, and the center has a red hue to it. My TV is also about 5 years old. I was afraid a repair would require replacement of some key components, but hoping it indeed just 'needs an adjustment. So, gotta find a TV chiropractor I guess.
Try cleaning the 11 element lens just in front of the lamp housing. If this doesn't completely clear the problem, then one or more LCD panels are faulty.
