i have a samsung dlp tv and recently it was turning off all the time and now it won't even turn on. when i turn it on the lights lamp (green light) and temp (red light) blink. so i dont know if it means we need to change the bulb or if its something else. and also we tried to change the lamp and we found where the lamp goes but in front of it is like a plastic frame that we would have to take out before we can replace it but it seems like stuck or glued inside, we don't know. and we can't see any screws or anything. i dont know if we should just try to get it out or if there's a better way. thanks for any help.
