I had the same issue but instead of shorting out the sensor, I removed the bulb assembly, cleaned the interior of the assembly and TV the best that I could with a vaccum and small paint brush. Once cleaned, I reinstalled the bulb assembly and the TV has worked for the last eight months with no problem.

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php But if you don't hear any strange noises,tv is around 4000 hrs,1-3 yrs it could be time to replace the lamp.The lamp you need is 915b403001 .Have a blessed one!

there is only a loosed part at the printed circuit board. try to open the back cover of your tv but be sure to unplug it before doing this, then try to unplug then plug the connectors in the power supply part but be sure to remember each location of the connector.

Samsung DLP 62 inch turns off by itself after being switched on


take off the lamp access door on the back and find the safety switch that the door pushes on. unplug the connector from the switch and put staple into the connector to short out the cable. Switch is probably bad. worked for me. same problem.

Samsung tv turns of by itself


The lamp can cause this but also a faulty lamp door switch will cause the same thing

We have a Hitachi C28W1TN, which is just under 10 years old that has recently started switching itself off. It goes onto standby by itself and when we switch it back on, it instantly does it again. At...


It's been a while since this post, but I may have had a similar problem with my Hitachi. With no reason it would switching on and off randomly. The problem was with a solder joint on main relay - it was cracked and would not keep the coil powered so i kept flickering on/off. This relay is located on the front of pcb, between high voltage area and the switch and on my tv it is blue. Check all four joints and apply some new solder onto them. Make sure the tv is not connected to mains ;-) Hope this helps
