My Samsung 61inc works for half an hour then just changes to a new blue screen, if you back to the channel that you were watching 2 sec later it will change back to the blue screen.

One of the most reasons that the samsung DLP tv will stop working is that the emergency switch on the back gets caught in the wrong position and makes your tv to turn off. Try to check the switch it is located under the lamp cover door. Good day and best regards.

I replaced the bulb in my Samsung HLP5674 wx xaa TV and now it turns off by itself intermittantly. How do I fix this?

You may have not gotten the lamp door switch positioned just right when you replaced the lamp door. It's been a common issue with Samsung in recent models. It's possible to defeat the switch by using a wire jumper across the switch plug and eliminate the problem all together if you're electronically apt.

I have a hl s5087w 50in tv and it keeps shutting off on me. I wait a little bit and it will turn back on but shuts off again. any ideas?

Look in the back of the set. You will find a Black Lamp Door with one screw at the top if your set is black. Remove the Lamp Door carefully. You might hear a click, If you do then reinstall the Lamp Door and tighten the screw. If you do not hear a click don't worry, replace the Lamp Door.This resets the Interlock Safety Switch. The switch gets hot and opens the circuit. Any time the rear case is removed you must do this as the rear case does not engage the Interlock Switch properly. If the tv comes on and you have a picture wait a while to see if the set turns back off, If it does then you might have a bad a Lamp and or Lamp Ballast. Take the Lamp out through the Lamp Door and look at the Front Galss. DO NOT TOUCH THE GLASS AT ALL!. If you see shattered glass, you have a bad lamp. If you do not replace the Lamp any way because the Lamps for this Model can look good and still be bad.

Samsung tv turns of by itself

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

Make shure that when you replace the lamp
the lamp door switch is in the up position before the door is put back on

Problems with the lamp door detector switch. Try jumping out this switch and running it for a while. The switch is the small switch with the blue rocker arm activated by the tab on the lamp door panel.

Sounds like the lamp to me. The projection lamps get hotter as they age and the TVs have a sensor to monitor the temp and shutdown the TV if it get too high
Projection TV makers charge an arm and a leg for their replacement lamps. They make it easy to do but as a result the custom lamp assy is expensive. The trick is to buy just the bulb for your model TV from any number of us aftermarket sources at a fraction of the lamp price and install it in the old lamp yourself. Really easy.
