In order to get my samsung hln467wx to work i have to power cycle it, by that i mean plug it in turn it on wait for a min then a picture comes up and its fine for a min or two then it goes all fuzzy and turns off then i have to unplug it and then plug it back in (the power buttons dont work once the screen goes all weird) after ten or fifteen times it finally works and stays on and all the buttons work again but if i turn it off it needs to be power cycled again to turn back on..........i opened it up and checked all the caps no buldges or broken ones any ideas??

Hello,
When you start getting the distortion on your screen, have you tried out if the PIP option is affected as well? The image distortion is notoriously caused by a digital video board, unless you test digital versus analog inputs and the results vary. If your set is sometimes not accepting commands like the power button, there might be something wrong with your DMD board, hopefully you can find one sold separately since most of these are sold as a unit on the complete light engine.
