Samsung model hlt4675sx\xaa projection tv wont work. the stand by/temp light flashes red and the lamp light flashes green? it makes the sound that it makes when it turns on but no picture. we looked at the back to c what it does. the fans turn on and the lamp light flashes then the tv turns off and the lamp light stops and so do fans. and then the the stand by/temp light flashes red and the lamp light flashes green.

It could be the temp sensor going bad. This sensor sits on top of the metal housing which the bulb assembly slides into. The bulb assembly will have a hole on top and this is where the sensor is above. There is a small blue and white wire that plugs into it. If you pull the wire out and put a paper clip or wire in the coupling you will basically bypass the sensor connecting the blue and white wire. If your tv turns on then that is your problem. Its cheap too. Here were my symptoms..1] Turn tv on 2] Bulb would light up..(which eliminates the ballast) regular picture would show up (which eliminates the bulb and color wheel) 3] 30 seconds later tv would shut down with 3 flashing lights. After bypass the tv turned on as always and hasnt shut down yet. Always un plug tv first. Get the replacement part to avoid overheating and possible fire
