Click on the exact model you have and there are service manuals for each model if you need them. Inside I usually find diagnostic trees that lead you to what parts to swap out.
Our Samsung HL-R5087W stopped displaying picture and no sound without any warning. When we turn it on, it makes periodic crackling sound and constantly trying to turning itself on and off. I opened the back cover and the crackling sound seems to be coming around bulb assembly. Whenever it makes the sound, I see a flicker of light just above bulb assembly. Is the bulb need to be replaced or is it related to some other issue? Thanks a bunch for your input.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
