First pop the focus ring of the lens assy using a wide flat head. remove 8 screws on the bottom,2 or 3 on the rear. pry the bottom of the front bezel away from the bottom of the projector being careful not to damage the tabs that hold the bezel to the top. repeat the same for the rear bezel, disconnect the speaker and the keypad from the top cover and remove the top cover. most likely the pop you heard would be the glass fuse on the power supply on the side next to the lamp door, but also could have been the power input board next to the on/off switch, OR the lamp may have exploded.

Samsung microwave suddenly went dead

You have blown a fuse. Check inside the oven chamber and look for missing powder paint or signs of arcing, if so there is a paint to repair microwaves for this issue or else just dispose of the microwave. If the inside is good remove all the screws and remove the cover. Replace the fuse. If the magnetron was making louder noises prior then replace the magnetron. Since the fuse went the giant capacitor is likely bad. While the cabinet is open make sure to look for burned wires, check the continuity of thermal cutoffs, and check the main circuit-board for burned traces or components. The relays in most electronics are known for arcing (spot welding) and staying in the wrong position. Tap them hard with the back end of a screwdriver. During all of this use safe electrical practices by having the power cord unplugged. The capacitor could still have a high charge on it so be careful.

Optoma movie time projector has a vibrating sound

Normally this sound noise is the small FAN inside. Dirty or faulty. You must open the proyector, or go to some shop repair.

God bless you

I was watching the TV until I heard a pop and the screen went completely black. The sound continued but I couldn't see anything.

That poped sound may have come from blown component in the backlight inverter board or in the 24vdc power supply. You have to open it up and inspect the inside for any sign of bad components.
Please read my guide to get more understanding.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Or just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

My projector it not working! i press the power button and it green light but it not light show can you please help me and also colour keep flashing.

Sounds like the lamp might have blown. Sometimes the projector can't tell if the lamp is blown, so the usual red indicator light doesn't show.

After the projector is on, if you push menu on the remote do you see anything? Maybe the brightness is just turned down all the way. If you see no menu when you push the menu button it's time to inspect the lamp.

Open up the projector and pull out the lamp. You'll probably need a screwdriver to remove the cover, and then another screwdriver to unscrew the lamp and pull it out. Be careful not to touch the bulb's insides. Is the lamp on the inside of the fixture bulbous, or cracked. Look closely.

My 42 inch flat screen was on and the all of sudden there was a big pop and the TV went blank. I could hear it clicking inside after this happened. Pulled the power plug to stop it. What caused the big...

It sounds like one of the Electrolytic Capacitors in the TV has gone, this can be caused by voltage fluctuations, Ambient Temperatures around the TV and sometimes they just fail for no apparent reason. If you are handy with some basic electronic tools you could open the back of the TV and you would possibly see the remains of the blown component as bits of paper like material around where a capacitor used to be.

Suddenly went blank while in use no power lighttotally dead

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for:
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Picture is out on LG LCD TV

The problem can be blown up components in the back lights inverter board or in the 24VDC power supply section. You need to open up the back look to see if you can locate blown components. There should be 24vdc on one of the power supply output connectors pins.
