Question about Mitsubishi WD-62525 62" Rear Projection HDTV
The wave was caused by the fact that the image was badly processed in the processor. The main cause for that is a bad power source that delivers an unstable tension to the processor .
On the other hand the noises you heard are always generated by the power source: the crackling and the static were generated by the transformers being severely overstressed and the booms by the exploding electrolytic capacitors.
What happened: the capacitors have aged and the power source has become unstable (generating the wave you saw); the problem got worse till one capacitor finally failed; unfortunately the source was too weakened to limit the failure and protect itself so the failure snowballed.
Result = the power source failed the big way and fried the entire tv in the process. The tv is fixable, but i seriously doubt it's worth the money you need to put in it to fix it.
Time for a new one.
