First is if this happened unplug the set as you may do more damage if keep trying to power it up.

Inspect in order:

The lamp this model uses.

The power supply board for burnt or damaged parts

A visual inspection of the boards including the ballast that drives the lamp

No luck and then you have to consider based on your skill level here to have the set checked by a technician.

Sounds like you may have an issue with either the ballast or lamp. I would check to see if you can isolate where the sound is coming from. You can get the replacement ballast and the Lam from www.tvrepairworld.com along with free instructions

SOURCE: Tv won't turn on.

Power supply is blown. Google it, check ebay (with tv model name) or just part it out and get a new one. You can also buy these used for really cheap off of craigslist.org

SOURCE: sony wega kdf-50we655 went off and thier is a buzzing noise

Anything that sounds like electrical crackling will be coming from either the lamp or lamp driver/ballast boards or their interconnections. The lamp should be examined first as this is the most likely cause.

SOURCE: "pop sound", picture out, burning smell...?

Usually, yes. A bulb that has audibly 'popped' will be apparently bad if you pull it out of the TV (shattered). Other times this is a lamp ballast board.

TV made a big popping sound, and then a crackling


Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php That crackling sound could be of the color wheel:The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is BP9601073A you can find original here:http://www.discount-merchant.com/Samsung-BP96-01073A-lamp-p/samsung-bp96-01073a-lamp-oem.htm?Click=48173 .Have a blessed one!

Wavey color lines at bottom of picture. Crackling noises coming from back bad picture


Howdy;
The "crackling noises" from the back is causing the picture to distort. 1) Either locate source of "noise" and correct or 2) Call a Service Company and get corrected. I would recommend that you DO NOT USE TV until this corrected. It may cause a fire inside your TV.

Good Luck, Big Irish.

#1 When I turn on the TV the power button comes on then blinks 6 times then goes off for a few seconds then repeats the cycle. I have sound over my surround system during this time but no picture.
#2 My sound would crackle and pop every once and a while until now it does nothing. I have to watch it with the surround sound on.

Something like this Id have someone who knows there way around electronics, a qualified tech or someone you trust really well :-) Does the crackling affect the TV picture at all ? My first guess would be dust and or dampness on the audio components. Sometimes this can conduct electricity across small pc chips and reak all sorts of havoc. I had an old Tomas electric organ once, and it actually caught fire because two speaker wires were rubbing together and eventually wore thru the insulation and shorted out, but it was also making alot of crackling and static noises. Try raising and lowering the volume low to high and high to low and see if the crackling noises gets worse. Some audio amplifiers put out quite a bit of power, so I wouldnt trust leaving the TV on without a fire extinguisher handy.
