hello everyone. i have a samsung 50 inch DLP model HLS5086 that having problems turning on. The tv will turn on by remote or the button in the front and it goes through it's normal cycle (lamp on, fans on, green lamp light blinking). After the green lamp lights stops blinking the tv will stay on for about a minute then turn itself back off. Now the vent cover in the back is pushing the blue switch down so i know that's not a problem. The bulb is new and lights up, and there are no odd sounds. Sometime it'll take hours of me just hitting the power button (after it turns off) to get it to turn on. Now, whenever the tv does turn on the picture is perfect. Anyone know what the problem can be. Thanks!!!
