Re: screen wont come on
Well keith if it is under warranty it is best not to do anything with it but get it brought back to the seller. doing something with it could nullify the warranty.
as to the unit, you have a problem with the power suopply that's why the fuse keeps on popping. it needs more troubleshooting. but as i said have it checked by the manufacturer first since under warranty.

The power outage probably popped an inside fuse or damaged some electronic components. If you are capable, unplug the tv and place it face down on a soft towel. Unscrew all the screws on the rear that hold the two halves together. Lift the back panel slowly making sure all is free. Look for the fuses and check if they are blown. If they are, replace them with the same rated fuses. This is the cheapest fix. If the fuses pop again after this, then something beyond the fuse was damaged. You will need a repair shop to troubleshoot it. Once fixed, plug the tv into a surge protector for future use. Hope this helps.
GOT SAME PROBLEM NOW IS THERE A FUSE WHERE POWER CORD PLUGS INTO THE SET ON THE BACK MINE HAS A GLASS FUSE NEXT TO THE PRONGS THAT COME FROM TV YOU HAVE TO USE A SCREW DRIVER TO POP IT OUT SHOWS A PIC OF IT IF YOU DON'T SEE IT DON'T TRY TO POP IT OUT
If there was a popping noise of any kind when the tv screen went black there's a high possibility that one of the fuses in the tv popped and there is no power to the tv. It could also just be the outlet itself and try plugging the tv to different working outlets.
This sound is a capcitor pop and this could be in the power supply unit itself. The glass could be a fuse that took the brunt from the capcitor pop.
1. Unplug the unit and do not plug it in.
2. if its under warrenty take it in please!
3. if its not under warrenty and you know eletronics verify what cap popped and replace that and the fuse.
4. if you do not know about eletronics this work would cost you around $150 for the wrok done.
Pop sound is probably the Lamp or maybe the color wheel. When you unplug and try it on do you hear a whirling or winning sound ? Is it followed by a slight ticking sound ? If you get the whirling and a ticking sound it's probably a bad lamp. If you don't hear the whirling sound you may have a bad color wheel. The parts are both made of glass. The pop you heard was one of them breaking. If you can't tell, order a lamp you will need to change it eventually anyway.
The fuse is blowning because most likely when you plugged it it, it took a power surge. And the power surge blow a proection diode. As long as you opened it up... in the power section you will see a bunch of diodes. Get a multi meter and check these diodes out. Besides the diodes... you will see a transformer.... if you are looking at the unit with the fuse to the left... then look to the right of the transformer... you will see a transistor on a metal heat sink... that could have blown also.. if that did... then you should also check the diodes just on the other side of the heatsink too.
Two things in your TV can make that popping sound. One is the bulb of course and the other is a capacitor. Have you pulled out the bulb to inspect it? My guess is that you have broken glass in the cooling fan, which is why there is a grinding sound. Most bulbs tend to contain the glass from getting everywhere as it's only the filament inside that pops creating little diamond looking pieces inside the lens. If a surge was strong enough or if the bulb was poorly manufactured, the whole unit can explode inside spraying glass everywhere.
If the bulb looks fine, the pop must've been a capacitor on one of your circuit boards resulting in no display. Since the TV still powers on, your power supply and it's fuse appear to be fine. Check the bulb first and go from there.
Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.
