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.
Thank you for any help you can give us.

After loud cracking noise no picture on plasma


The most likely the TV has a power supply related problem. A power surge can cause the problem. Last thing you want ot do is void the warranty by opening up the TV. Here's info to get your warranty started:

Loud popping noise


The 23" CRT set may have a high voltage breakdown in the flyback transformer or focus divider. Take the back off and operate the set in a dark room. Look for anything that has a blue glow around it or sparks flying when the pop occurs. I won't guarantee this will find your problem, but it is definitive if you see these!

I once had a set with these symptoms. I stopped the blue glow and arcing by covering the focus divider with epoxy. It worked for a couple of months before the divider literally broke apart.
