Question about Samsung DLP HL-P5663W 56" TV

1 Answer

Samsung HL-S5087W shuts off.

I believe that the problem is that the safety switch next to the lamp door is defective. I need part number and cost for this part.


The other day the TV was shutting off every 5 minutes. I opened the back door to check for dust and or fan operating. After replacing the door the TV worked continuously for many hours. I think that contacts on the switch get corroded and opening the lamp door will clean the contacts on the switch.

I almost sent my TV to the shop a year ago with the same problem. After opening the lamp door and checking that it was properly set, the TV decided to work just fine for over a year.

My tv don"t start i put new lamp and new balasts, when i press the power tv sound comes for few seconds no ligth and shuts off then three light at the front turns on lamp timer temp, some one can help me...

Be sure you have all cables plugged in inside . Is the lamp door switch broken. When you put the back on you could have damaged the switch. You can sort the wires to test. remove the lamp door and besure the tab on the door presses the switch downward.If switch is ok it sounds like a wire is loose are connector was not plugged back in.

It keeps shutting off. Anywhere from 2 or 3 times

Could be several things. First replace lamp.Remove lamp door and put it back on making sure tab on door presses door switch downward when closed. Can you heard spinning noise from front. Bad color wheel will cause shutdown. Look at big cap on ballast . iff swollen replace lamp, ballast and power board. Is voltage to ballast from power board below 350 volts if so replace power board. hope this helps. Most common are lamp and door switch in up position rather than downward .

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 DLP HL-P5063W. . .no lamp!

Remove the rear cover and check the lamp cover switch. Earlier versions used a black plastic switch holder that may break due to improper assembly. The part number for the holder is BP61-01240A. Newer versions use a metal tab attached to the engine. In this case, improper assembly may cause the lamp cover switch to be extended past its range, either breaking the switch or causing it to have an open contact. Replace the switch with BP91-01231A.

Note that in these models, when reinstalling the rear cover, it is best to remove the lamp cover first, install the rear cover, then install the lamp cover. This will make sure that the lamp switch is properly engaged.
