I'm having a problem with my Samsung hls4266w and couldn't find an answer.
My tv powers on completely normally and the lamp goes to its full brightness. The picture and sound will remain perfect for about 15 seconds then the entire set turns off. There is a low whirring noise, then all 3 buttons begin to blink. (timer, lamp, and standby/temp) This process can be repeated over and over
From the information i have gathered from the net i believe the color wheel to be the culprit (i am fully certain that the switch detecting the removal of the lamp plate is being held in place.) Before i embark on a project like replacing a color wheel i was hoping for some confirmation from someone wiser then me.
