Loud cracking noise sounds like fireworks and wont get a picture

Over the past few weeks everytime we turn on the tv there is loud cracking noises. After turning on and off a few times we would finally get a picture with no sound then after a few more attempts there would be sound with picture. Now there is only the loud cracking noises. We have only had this for two years.

Samsung HLS5086WX/XAA made popping noise and shut off, then made whirring noise.


When my TV did this in the past it ended up being the color wheel. I had someone replace it and it worked fine. I asked it if had to be calibrated after it is installed and he said no. Also make sure the door switch is pushed down when you install the back bulb door. Sometimes this switch can go bad as well.

Loud noise now tv wont turn on


More than not if it is a loud noise shortly after you turn the set on, the color wheel is bad. The color wheel is not available by itself and requires the complete light engine to be replaced. The part number for the light engine is 75002250. I would suggest having a technician replace this for you if this is the case. Please take a moment to rate my answer. Thanks...

My TV is making cracking noise


Its the plastic cassing making the noise. If you press the tv together along the edges you will here a crack. Samsung and others did not use 99 cent padding between the plastic and the metal you need cushion padding. Its like not using a gasket or seal. Its a simple fix but the tv companies say its expansion.

Samsung DLP loud vibrating noise


The color wheel is the most common problem in DLPs that cause noise. To determine the cause: Turn the set off. If the noise goes away after about five seconds, then, the problem is the color wheel. If the noise goes away one to two minutes after shut off, then, the problem is a fan. You can find an Authorized Servicer in your area that can tell you the price of repair, by clicking on the Samsung link: http://www.samsung.com/Support/ServiceLocations/index.htm
