Question! My picture and sound both went out at the same time on my Samsung HLN437W yesterday, plus I had the 3 blinking lights. I took out the lamp carrier and checked it out and put it back in and picture and sound came back on, but later did the same thing again. It has 16,437 hrs on the orig. bulb and before I order a new one Monday, is it just the bulb or is there more going on then the bulb. I not sure if the sound also goes out when the bulb does?
